Oh boy genetics.... Now I know that tune, who wants to dance??



To be clear here we are talking about genes and not genetics. Genes, in and of themselves, do not "want" anything. A gene is nothing more than a unit of information, it has no "wants" or "goals".



A mutation is no more "bad" than it is "good". A mutation simply is. However, how that mutation effects the organism can be said to be "bad" or "good" but that is totally arbitrary depending on who/what is making that determination. For example, most everyone would agree that Sickle Cell Anemia is "bad" and yet, in parts of the world where malaria is rampant, being a carrier for the Sickle Cell gene gives you a resistance to malaria which most people would say is "good". So, is Sickle Cell "bad" or is it "good"?



You cannot say that they weaken the species, I am sorry Scot. You are putting a trait on genes that simply is not there, basically you are personifying them. I am tired of the "good"/"bad" label because it simply is not applicable so let me use what geneticists use: "Fit", which brings us also to one of the single most misunderstood ideas in genetics/evolution, the idea of "Fitness".

A gene is "fit" only in relation to other variants (alleles) of that same gene it has nothing to do with the organism as a whole or how that gene relates to other genes.

So, genetically speaking, Wacky Traps (aka Bart Simpson) and Pugs and Persians and Parrot cichlids are all very much genetically fit because the genes for those traits have survived the process of selection. I grant you that that selection was at the hand of "man" and not "nature" but that simply does not matter.

The species in and of itself is not weak. There are numerous other alleles of those genes out there and if the selective pressure switches then the unfit genes will be culled from the population and new ones will take their place.



Again, genes do not want, they simply are. You must quit personifying them.

And for the record, cancer is actually the ultimate in fitness from a genetic stand point. Immortality is the ultimate in "self-preservation".



Just because a mutant gene is present in a pool does not by default mean that pol is weakened. Again I point you back to the Sickle Cell gene, outside of malaria regions it is not a fit gene but within those malaria areas it is most certainly a fit gene, and purging it from those populations would actually hurt them. I can think of many other cases where the presence of a mutant gene actually ended up conferring a fitness unto a population by its presence.

So, you cannot correctly say that mutant individuals will, by default, harm the population.



That argument does not stand up to reason though. There are perfectly normal looking plants from perfectly normal looking parents that are in no way genetically related to "cup traps" and yet harbor "weakness" genes and could produce weak offspring. Whether a plant grows weakly is likely not the result of a single gene. Every year people are producing plants from crosses where they sow the seed out and a few years later the weak plants have died or been pulled but the strong plants are sent out to others likely carrying some of those same genes that made their siblings weak. And yet no one baulks about that.



The example hits a flaw though. While you may not like those genes popping up in your collection some one else may. I can relate this back to a snake breeder who bred a couple snakes together looking for one result (piebald) and got out another (piebald, axanthic and piebald axanthic). He was not aware that either snake carried the axanthic gene but he was thrilled to discover they did.


When we are dealing with such things as "desirable" mutations there is always a level of subjectivity on what exactly is desirable. You do not like cup trap and I do. I do not like fused tooth and you do. So what happes is that I do not breed fused tooth plants and you do not breed cup traps and some people will want my plants and some people will want your traps and then one day someone who wants a fused tooth cup trap will get both of our plants and breed them together and get something new and unusual that will rock the VFT community. So while we each have our dislikes the genes behind those dislikes still have their fitness under the selective pressure of the collector. No "good". No "bad".


Well said Pyro, i couldnt have come near to saying it any better myself!

Great post Travis, +1million!

I actually wanted to share a tray of Cupped Traps with you all- while some clones may be weak... I definitely disagree that all of them are. I have had some typicals that looked far worse than these... A picture version of what Travis just said I guess haha

TC also aint any more likely to produce weak individuals than seed grown.......ive had around 100 seeds from a nep a couple different times, say all 100 germinate about 30-50 get culled either by me cause of weak growth i dont approve of or by "nature" cause they dont want to adapt to my rough growing techniques and just keel over at some point.....some of the weakest growing plants i have seen in CP's or in most any other plant group are seed grown.....if you buy a small seedgrown plant your generally running a higher risk of getting a weak individual than by buying a plant from a known TC clone.....

seed grown plants have their place and i encourage ppl to get them but screaming from the roof tops that they are some how superior growers to TC plants is plain stupid and comes from individuals with no experience with actually growing large quantities of plants from seed......

So, genetically speaking, Wacky Traps (aka Bart Simpson) and Pugs and Persians and Parrot cichlids are all very much genetically fit because the genes for those traits have survived the process of selection. I grant you that that selection was at the hand of "man" and not "nature" but that simply does not matter.

you are wrong about pugs and persians and parrot cichlids..
they really are remarkably "weak" simply because they have bred to be "cute"..
Persian cats and pug dogs have been bred to have flattened, smooshed faces, so they look more human and "cute"..this results in breathing problems, asthma, and shortened life.
these are very inferior animals, compared to the ideal of the species..
they would never survive in nature..they are inferior animals, bred, on purpose, by humans, to be deliberately deformed..which causes the animals to have medical problems..
how is that not "weakness"? then when people breed these poor animals with other breeds, it introduces these genes into the larger gene pool of the entire species..

If humans ceased to exist, eventually these traits would be culled out..which would be a good thing..but as long as humans exist these "weak" animals will be allowed to exist, and suffer..

Parrot cichlids often cant eat normally, because their mouths are so seriously deformed..on purpose..they have a shortened lifespan because they are so inferior to the "normal" varieties they are derived from..again..thats a deliberate man-made weakness, all in the name of novelty and making money..

Can Bart Simpson VFT's actually catch bugs? if they cant, thats a weakness and a disadvantage for that plant..when those plants are bred with "normal" VFT's, the genes are allowed to enter the main gene pool..


And for the record, cancer is actually the ultimate in fitness from a genetic stand point. Immortality is the ultimate in "self-preservation".

I dont understand what you mean by that..how is cancer immortal?


So, you cannot correctly say that mutant individuals will, by default, harm the population.

yes I can say that..the entire population of Persian cats is very much harmed..
they cant breath properly, they often have asthma, all in the name of smooshed "cute" faces..of course that is deliberate harm..how can it not be harm?

and if those genes get into the general cat population, you end up with cats with characteristics that have the potential to cause harm..weakened cats..which would not happen naturally..

I dont see how it cant be conisdered harm, or weakness..

tell me how a Pug dog or a Persian cat or a Bart Simpson VFT is MORE fit (or even equally fit) than a "typical" variety, and maybe I will believe you..but you cant do that..because its simply not true..because they are most definitely less fit..bred to be less fit purposely by humans..only for the novelty, or for making money..how can that be considered a good thing?

I do believe that the point was that they are not weak because it's people making the selection, not nature. They may be less healthy, but so long as people select for those traits, the genes are more fit. The difference of opinion lies in that reference frame. A gene may lower fitness by natural selection, but as you well know, this is a case where it isn't "nature" selecting.

I dont understand what you mean by that..how is cancer immortal?

I'm sure Travis can better elucidate than I, but here goes. Cancer shuts down apoptotic pathways -- that is, it prevents cells from "killing" itself because it is damaged. Normally, when a cell ceases to function correctly, apoptosis (programmed cell dead, as it's often referred to) is used to cull the cell. Furthermore, there are lines of cancerous cells which have been used in lab and successfully reproduced for the past 50 or 60 years (search HeLa for more).

Other mechanisms are induced that prevent cells from senescing (eg, search telomerase). These cells can reproduce and continue to function as cancer cells indefinitely.

tell me how a Pug dog or a Persian cat or a Bart Simpson VFT is MORE fit (or even equally fit) than a "typical" variety, and maybe I will believe you..but you cant do that..because its simply not true..because they are most definitely less fit..bred to be less fit purposely by humans..only for the novelty, or for making money..how can that be considered a good thing?

It doesn't have to do with "good" or "bad". The fact that these traits are novel and selected for by humans by definition makes them more fit. It's not traditional "natural selection", but it is selection for a trait that increases the organism's probability to survive and breed (as facilitated by people).

this is part of a removed post. Doesn't need to be quoted. ;) -- Est

sirkrisstoff, i understand your stand point entirely but i think you mightve taken this to a certain personal level not intended. what i got from what scot wrote was that humans trying to make a species look, act, grow, etc. the way they want has caused irreversible and detrimental damage to said species (talking specifically about the dogs). in THAT way making them "weaker" then their un-altered counter-parts (un-altered as in by any other means except natural). i might be wrong and scot might be a complete scumbag but im giving him the benefit of the doubt to hopefully explain himself or at the very least apologize for not thinking before posting.

they have not made the species weaker they have made certain lines potentially weaker were they to be dropped off in the wild.....most the mutations being talked about such as the short muzzle of pugs and persians are far from set in stone though.....only way to keep the short muzzle is to keep breeding with short muzzled individuals.......introduce them to the general population and that trait disappears quickly which is why all the rez mutts here tend to look the same.....that short muzzle does not hurt the gene pool cause it is a very recessive trait easily removed, not a dominant one......

besides in a normal persian or pugs "natural environment" it aint much of a handicap because of human intervention taking care of them.....it helps them cause ppl want them and want to care for them.....as Travis said its a positive, not a negative....when introduced back to a natural gene pool it disappears quickly and does no real harm except to the individual, it most defiantly does not harm the population as a whole....

hmmm..interesting concept..
(I had forgotten that concept was brought up a few days ago! and that I agreed with it on a basic level..which I do.)
so the deformity is considered a benefit, because its what the humans select for, thus what I consider a weakness is actually a strength for that variety..
ok..thats basically logical..
but it still makes the organism weaker when compared to its natural form..

Pug traits survive because humans have selected them..
therefore Pugs are "fit" for basic survival..
but its still a very weak, sickly animal in reality..even though it does technically survive through human intervention..

I see your point..but I still cant accept that these characteristics are actually strengths in reality, because to the organisms themselves, they are real drawbacks..even if they do allow them to actually exist in the first place..

yes, Persian cats would not even exist, at all, if they hadn't been created artificially..
but IMO, they shouldn't exist..I consider it cruel to deliberately create animals with deliberate deformities that cause them to have health problems.


I'm sure Travis can better elucidate than I, but here goes. Cancer shuts down apoptotic pathways -- that is, it prevents cells from "killing" itself because it is damaged.

.

ok fine..again that makes sense from a viewpoint of basic logic..
sure, to cancer cells, cancer is wonderful thing..
sure, cells dont die because of cancer..ok fine. ;)

It might be "good" for those individual cells..in the short term..
but human cancer cells cant exist outside of their "host"..which they will eventually kill..

Try telling the person actually dying of cancer that "cancer is actually the ultimate in fitness from a genetic stand point."..
see if that cheers them up any.. :-(

Nobody said it would or should. You asked how cancer cells are immortal -- I told you. Travis mentioned it in passing as a sidenote. It's noteworthy because "genetic fitness" is not always what we think of as good. As is the case with these "designer animals".

but IMO, they shouldn't exist..I consider it cruel to deliberately create animals with deliberate deformities..

That's fine, that's your opinion and you're fully entitled to it. However, you can't logically argue that they're less genetically fit for this environment (in which human selection is such a significant pressure).

Aaaand with that it was all resolved. :p

Re: 'Cupped Trap'

I've been growing this clone for nearly 3.5 years and don't find it any more vigorous than any of the dozens of "typicals" I have. Indeed I find that many of it's annoying habits make it less likely to thrive than your average typical (how's that for redundancy). I've had maybe five or six die on me since I found the one I started out with in a local Home Depot. Fortunately the first thing I did was cut the flower stalk on it and send it to a friend to propagate in tissue culture. Thus I had backups available.

The Good:

The first year out of tissue culture it grows splendidly (but what flytraps doesn't).
I find it to be an attractive looking mutation. Yes, the traps are fully functional and are capable of catching prey on their own. The traps are sometimes slower to close than "normal" form traps but they still catch prey.
Under lights or very strong sunlight they color up nicely, but then again so do many flytraps.

The Bad:
They flower constantly whether you clip the flowers early or not. 8 flower stalks over the entire growing period is the record for me so far.
Worse than that this plant has a tendency to divide when they flower. While you may think this is a good thing the result is that the rosettes never get much bigger than two or three inches across. And the survival rate of the divisions are poor.
Also the flower stalks are relatively thin. You are more likely to get strikes from thicker flower stalk cutting for obvious reasons.
They go through trapless phases. Either tiny traps or just a "tendril" or nub instead of a trap. Usually this happens for the first month or two after coming out of dormancy or while flowering (clipped or not) but can happen at any time. I've had two plants in the same pot (flower self-divisions from the previous year) one without traps the entire growing season

Next person to post a picture because "lol this thred is dum" is gonna get smacked. I'm tired of a thread getting a little dicey and then dragged past the point of return by people posting a funny picture. It just leads to more pictures, more useless posts, and doesn't contribute to the thread.

If you think a thread is dumb, don't participate. If you think there is something inappropriate going on in a thread, report it. If you have something useful to say, by all means contribute.

And if a thread is supposed to be dumb, by all means, post funny pictures all day. Facepalms (etc, etc, etc) are not particularly informative, however.

When talking about fitness here it should be the biological context of fitness but I am mentioning this point in case some people may be using the common use of fitness to describe physical condition. Biological/genetic fitness of an individual refers to an organisms ability to reproduce and pass on its genes. Basically fitness boils down to how many offspring you leave behind. NOT how physically fit you are or how hardy and vigorously a plant grows, etc.

I doubt the average show cat, squished-nosed, pedigreed Persian cat would last long having to hunt down meals in the wild compared to a normal cat. Dump both cats off in the wild and in that case your average cat would likely have the higher fitness because it would survive longer and be able to have more litters than the Persian. But compare the same two cats in a domestic situation and chances are the pedigree show cat will be in demand as a sire due to its pedigree and breed while the only action the standard cat would have is what it could sneak on its own, if it wasn't neutered first. Compare that to the persian with a waiting list for breeding opportunities the persian's fitness would be higher.

There is no one absolute fitness that is THE best. Fitness does matter on the environment. One organism may have a particular set of genes which gives it superior fitness in one environment, say for a plant a wetter one, where it has many offspring but move that same individual to a new environment which is dryer it is less fit if it does not reproduce as well compared to others individuals which have sets of genes which allow them to reproduce better in a dry environment compared to a wet one (and vice versa).

Not sure if this was a confusion for anyone reading but figured if it was it would clarify what the term fitness is..or should...be referring to.

Just because that giant steroid pumped muscle-bound guy at the gym might be physically fit (albeit gross looking)...well steroids are not necessarily the best thing for his reproductive fitness due to some..undesirable... side effects :blush:

Well said.
How often we forget that we are a part of the system also.
If a plant were mutated, and began a new strain growing with little or no defenses and highly susceptible to diseases, highly desired as a delectable food-source for animals and bugs, and perhaps even if it were very fragile and difficult to grow, (growing only on the mountain peaks of some tropical forest perhaps or some such rare/extreme environment) ...it might not be a "BAD" mutation!

In this day and age, it would only have to have leaves of sterling silver, flowers of solid gold, roots that would kill/cure cancer in humans, and a perfumed scent that made one feel intoxicating pleasure or relief from pain, and believe me, even with its "bad" traits, it would certainly grow and thrive miraculously!

It would do this WITHOUT building up resistance to disease, animals or bugs! Because it would offer US so much that WE desire, we would make sure it survived and would attempt to grow it and perpetuate its species (and possibly keep it from others, make it illegal, or who knows what else!)!

Point being, WE also can help determine if a plant is to live or die too! Like the Bart Simpson VFT's, they propagate and multiply and live on, simply by the people who like it, want it and grow it! How many plants and animals died off in extinction because of US! If we don't value it, we often let it die, or destroy its environment. If however we do value a plant, we take steps to preserve and protect it! In essence, if you could get high or cure cancer with Bart Simpson VFT's, people's opinions of it would change miraculously!

WE have altered the environment so much on this planet, that the normal "natural" rules and environments are not the only ones to consider any more! (As was mentioned, as far as preserving a variety of plant or animal and perpetuating the species, sometimes we pick a "weaker", less healthy individual and desire it more because of its other characteristics that strike our fancy, than the healthy but less "attractive" one!) Humans do not always base their "desires" on the most logical premises. Indeed, "novelty" and "money making" have become a part of our environment, as well as the environments of everything else on this planet! (Duh, where have you been if you don't realize this!)

Truly, we do not realize how important WE are in this process now, as well as how important our decisions and actions are, on this planet!

Est and Rattler hit most of the points on this but I wanted to just touch back on some of it as well

you are wrong about pugs and persians and parrot cichlids..

No, I do not believe I am.

they really are remarkably "weak" simply because they have bred to be "cute"..
Persian cats and pug dogs have been bred to have flattened, smooshed faces, so they look more human and "cute"..this results in breathing problems, asthma, and shortened life.
these are very inferior animals, compared to the ideal of the species..

Physically, I agree. they are weaker animals than, say, a German Shepherd. But we are not talking about physical fitness, we are talking about genetic fitness.

As I noted, this idea was touched on by a few others but really quickly:

These subsets of a population (note, it is not the whole population that we are dealign with in these situations) are genetically fit because the traits (i.e. phenotype) conferred by the genes is desirable (to some, not necessarily to you) and therefore the genes are under positive selective pressure to maintain their presence in the selected pool. So these animals are genetically fit.

they would never survive in nature..

But we are not talking about "in nature". I never once said "natural selection" I said "selective pressure". Breeding for certain breed traits is a selective pressure (hence the term "selective breeding") it has nothing to do with nature but the end result is much the same: Traits that are fit (genetically fit, not physically fit) are the ones that survive.

they are inferior animals, bred, on purpose, by humans, to be deliberately deformed

Yes, exactly. And those deliberate deformities are genetically based so those genes are fit under the selective pressure they have been subject to

..which causes the animals to have medical problems..

Irrelevant to the argument of whether they are genetically fit.

how is that not "weakness"? then when people breed these poor animals with other breeds, it introduces these genes into the larger gene pool of the entire species..

Yes, outbreeding introduces the genes to a larger pool (not the entire pool though, unless you breed them to every other breed out there which cannot happen for more reasons I care to go into at this moment.) Even then it does not "weaken" the pool. Yes the genes are present but, if they are selected against then their fitness drops and they are purged and if they are selected for then they remain fit and remain in the pool.

If humans ceased to exist, eventually these traits would be culled out..which would be a good thing..but as long as humans exist these "weak" animals will be allowed to exist, and suffer..

Yes, because the selective pressure would change. They genes would lose their fitness. But that does not change the fact that in the here and now, those genes are absolutely fit.

Can Bart Simpson VFT's actually catch bugs? if they cant, thats a weakness and a disadvantage for that plant..when those plants are bred with "normal" VFT's, the genes are allowed to enter the main gene pool..

IF the plant were in the wild it would be at a selective disadvantage I agree. But we are not talking about a plant in the wild. How many carnivorous plants in cultivation have to rely on their ability to trap bugs? It is irrelevant in cultivation how good or bad it can trap bugs because in cultivation LOOKS are king and Bart Simpson is wonderfully fit

I dont understand what you mean by that..how is cancer immortal?

I'm sure Travis can better elucidate than I, but here goes. Cancer shuts down apoptotic pathways -- that is, it prevents cells from "killing" itself because it is damaged. Normally, when a cell ceases to function correctly, apoptosis (programmed cell dead, as it's often referred to) is used to cull the cell.

Other mechanisms are induced that prevent cells from senescing (eg, search telomerase). These cells can reproduce and continue to function as cancer cells indefinitely.

More or less the nail on the head Est.

ok fine..again that makes sense from a viewpoint of basic logic..
sure, to cancer cells, cancer is wonderful thing..
sure, cells dont die because of cancer..ok fine. ;)

It might be "good" for those individual cells..in the short term..
but human cancer cells cant exist outside of their "host"..which they will eventually kill..

Not all cancers kill. And as Est noted:

You asked how cancer cells are immortal -- I told you. Travis mentioned it in passing as a sidenote. It's noteworthy because "genetic fitness" is not always what we think of as good.

Cancer is a very noteworthy example of how something we consider very bad has a very high genetic fitness.

Try telling the person actually dying of cancer that "cancer is actually the ultimate in fitness from a genetic stand point."..
see if that cheers them up any.. :-(

Scot, that is a rather low blow.

I am not some heartless cruel bastard who gets a kick out of wantonly hurting people. I would never make such a comment to a person with cancer.

We were (I thought) having an intellectual discussion and I answered in an intellectual sense, something that is scientifically interesting and noteworthy. I do not appreciate you twisting it into such a callus emotionally charged one and implying that that was my intent.

yes I can say that..the entire population of Persian cats is very much harmed..
they cant breath properly, they often have asthma, all in the name of smooshed "cute" faces..of course that is deliberate harm..how can it not be harm?

and if those genes get into the general cat population, you end up with cats with characteristics that have the potential to cause harm..weakened cats..which would not happen naturally..

I dont see how it cant be conisdered harm, or weakness..

You are talking about the ideas of physical fitness and genetic fitness as if they were the same thing when they are not.

Persian cats are not harmed, genetically, because the genes for the phenotype are maintained in spite of the fact that they are physically deformed. Breed selection maintains the genes. The genes are fit. The Persian cat population is not harmed because the genes are maintained. To remove the genes that cause the phenotype would harm the population because it would result in the breed no longer existing.

If the genes "escape" the breed pool then so what. Selective pressure will work on them as it will work on them. If they end up in a pool where they are unfit then they will be eliminated. If they end up in a pool where they are fit then they will be maintained.

tell me how a Pug dog or a Persian cat or a Bart Simpson VFT is MORE fit (or even equally fit) than a "typical" variety, and maybe I will believe you..but you cant do that.

I most certainly can do that. That they exist and perpetuate proves they are fit. Just because you do not like them does not mean everyone does not like them. Put a typical VFT and a Bart Simpson down in front of a newbie and tell him he can have either one of them for free and I would bet that probably greater than 50% of the time the newbie would take the Bart Simpson. That is selective pressure. That is fitness. Remember that we are talking about a morph in a hobby where morphs have value, no matter how physically screwed the morph may be. Because the morph has value it is more fit than the typical.

As another example let me hit my other hobby: snakes. One of the most popular snakes for people is the ball python which has over 60 base mutations (i.e. morphs). On any given weekend I could go to a reptile show and buy a normal ball python for $10. But if I want a morph the price immediately goes up by an order of magnitude and that is for the morphs that hardly look different from the normal ball pythons. Get to something that looks really different and the price tag goes up even more.

The fact that morphs are different gives them value (no matter how right or wrong you personally feel on the matter). That they have value means there is a selective pressure on morphs. That selective pressure results in them becoming more fit under cultivation regardless of how fit they may or may not be in the wild or how physically well off they may or may not be.

because its simply not true..because they are most definitely less fit..bred to be less fit purposely by humans..only for the novelty, or for making money..how can that be considered a good thing?

Again, you are blurring the line. They are genetically fit. It does not matter if they are physically unfit.

And please quit harping on the money aspect. I challenge you to find anything in this world that does not come down to money. Our hobby started out cause some redneck hillbilly decided to dig up VFTs from the wild and sell them for their novelty to make a quick buck so our hobby is terrible and horrible.

All dog and cat breeds are purposefully selected to maintain the breed standard only for the novelty and to make money. All bird and fish and cow and goat and horse and sheep and corn and wheat and bean and mouse and rat and gerbil and... I could go on forever. All of these and more have novelty and, in the end, financial gain for someone. Have you ever owned a dog Scot? Was/were it/they mutt(s)? If you answered "yes" to the first and "no" to the second then you are a hypocrite because you are trashing the maintenance of one breed while perpetuating the maintenance of another.

so the deformity is considered a benefit, because its what the humans select for, thus what I consider a weakness is actually a strength for that variety..
ok..thats basically logical..
but it still makes the organism weaker when compared to its natural form..

And again, we are not talking about "nature" because a Bronx apartment is not natural. Nor is an Atlanta mansion. Nor an L.A. condo.

And we are not talking about the organism itself but the genes.

Pug traits survive because humans have selected them..
therefore Pugs are "fit" for basic survival..
but its still a very weak, sickly animal in reality..even though it does technically survive through human intervention..

Exactly

I see your point..but I still cant accept that these characteristics are actually strengths in reality, because to the organisms themselves, they are real drawbacks..even if they do allow them to actually exist in the first place..

We are talking about the genes. The traits come from the genes. And technically the traits are not a drawback because if they were then the genes for them would not have been selected.

The traits of cute cuddly are what made people want them and are what are perpetuated. Yes, hand in hand with cute and cuddly comes breathing problems and what not. Does not change the fact that cute has "survival" value in this novelty oriented culture (and when you consider how old some of these breeds are it is obvious they have very high survival value).

yes, Persian cats would not even exist, at all, if they hadn't been created artificially..
but IMO, they shouldn't exist..I consider it cruel to deliberately create animals with deliberate deformities that cause them to have health problems.

Well, a single personal opinion does not mean much on the broad scale of selection. You do not like them. Fine, no one is asking you to. Heck, I do not much like them either. But some people do and they will maintain the genes in the breed population. Same with Siamese and Rhodesian Ridgebacks. Same with Manx and Bernese Mtn. Same with Tabby and Labrador. Each breed has its own fitness and within the breed it is very fit.

well..yes they are less genetically fit for this environment..
just because they are less genetically fit, period.

No. They are perfectly genetically fit for this environment because they have been selected for this environment. They are not "less" genetically fit, they are not "more" genetically fit. They simply are genetically fit. "More" and "less" are subjective. A chihuahua is "more" genetically fit than a St. Bernard when it comes to living in the purse of a Beverly Hills princess. That same chihuahua is "less" genetically fit when compared to that same St. Bernard when it comes to digging a man out of an avalanche. But you cannot make the blanket statement that either animal is "more" genetically fit or "less" genetically fit period end of discussion. With no point of reference there is no "more" or "less"



When talking about fitness here it should be the biological context of fitness but I am mentioning this point in case some people may be using the common use of fitness to describe physical condition. Biological/genetic fitness of an individual refers to an organisms ability to reproduce and pass on its genes. Basically fitness boils down to how many offspring you leave behind. NOT how physically fit you are or how hardy and vigorously a plant grows, etc.

I doubt the average show cat, squished-nosed, pedigreed Persian cat would last long having to hunt down meals in the wild compared to a normal cat. Dump both cats off in the wild and in that case your average cat would likely have the higher fitness because it would survive longer and be able to have more litters than the Persian. But compare the same two cats in a domestic situation and chances are the pedigree show cat will be in demand as a sire due to its pedigree and breed while the only action the standard cat would have is what it could sneak on its own, if it wasn't neutered first. Compare that to the persian with a waiting list for breeding opportunities the persian's fitness would be higher.

There is no one absolute fitness that is THE best. Fitness does matter on the environment. One organism may have a particular set of genes which gives it superior fitness in one environment, say for a plant a wetter one, where it has many offspring but move that same individual to a new environment which is dryer it is less fit if it does not reproduce as well compared to others individuals which have sets of genes which allow them to reproduce better in a dry environment compared to a wet one (and vice versa).

Not sure if this was a confusion for anyone reading but figured if it was it would clarify what the term fitness is..or should...be referring to.

Just because that giant steroid pumped muscle-bound guy at the gym might be physically fit (albeit gross looking)...well steroids are not necessarily the best thing for his reproductive fitness due to some..undesirable... side effects :blush:

Thank you Alleged. A wonderful explanation.

But we are not talking about physical fitness, we are talking about genetic fitness.

No, you arent talking about physical fitness..
but I am..and have been all along.

if you dont want to, thats fine..
but physical fitness is definitely part of this whole concept..
if you want to ignore that part of it, thats up to you..

We are really debating on two different levels here..
personally, I dont care about "genetic fitness"..
its the results of your "genetic fitness" that makes the animal "physically UNfit"..
to me, thats the main issue here..
I really dont care if the genes themselves are fit or not..
the end result of your fit genes is that you have a Persian cat who cant breathe properly..
you have a Parrot cichild that cant eat properly..
you have a Bart Simpson and Cup Trap VFT that cant even catch an insect!
thats a pretty serious physical limitation..

VFTS are designed to catch insects..to suppliment their nutrition..
sure, maybe a Bart Simpson VFT will technically survive..but being able to only photosynthesize,
it is missing out on a lot of nutrients it needs to be fully healthy..

thats a seriously flawed VFT..

the one trait that makes it a Carnivorous plant in the first place, its one unique feature, (its trap, and method of carnivory)
that no other organism in all of creation has, is gone..
denied..all in the name of novelty. and being denied its means of full nutrition, of course it will be weaker..

But you cannot make the blanket statement that either animal is "more" genetically fit or "less" genetically fit period end of discussion. With no point of reference there is no "more" or "less"

Yes I very much can make that blanket statement..because its simply true.

What you keep choosing to deliberately ignore is that there IS a point of reference..
the point of reference is the natural form of the creature or plant in question.
using that point of reference, they are most definitely less fit.
period, end of discussion.

since you refuse to even acknowledge that..well..there isnt much left to say..

I think we have both made our points quite well..
but since we are both deliberately ignoring the other's half of the argument, there is much point in continuing! ;)

I know you all are having fun trying to get your point across to the other....
slap: :poke: :headwall::blahblah9xm: :puke2: :comp: :-P-: :lac::blahblah9xm:

And watching the way you feed off the others comments reminded me, there are many plant+animal symbiotic relationships in nature. And they have developed via natural selection and have survived as well as they have simply because another species finds them valuable! (An example would be: the ants that tend and grow a fungus and then feed off of it.)
And there are lots of others!

Anyway, I know this is just about the disagreeing and debating at this point, so while I would suggest this:
:beer: and :hug:
I will let you get back to it! :rant::nono::poke::censor::redx: :nana: :crazy::lac:
It has been interesting at times watching you go at it! Nothing like a pissin' contest! :-))

(Funny, we developed naturally with TWO ears and only ONE mouth, why do you think that is?) Perhaps there is something you AGREE about? Well.....
Have fun kids! Play nice!

Since you are talking about genes and use “fitness” that means you should be using the reproductive biological meaning of fitness. That is just what fitness means in genetics/ biological terminology. When you actually mean physical fitness you need to be explicit that you are talking about physical condition or weakness…otherwise there is the confusion about what you actually mean when you say “fit” since obviously people were coming in on fitness from two different meanings of scientific versus colloquial fitness.

Now for more debating fun! Note: I’m not trying to insult or want to actually piss people off, I just find this fun to debate and actually have a moderately intelligent conversation with someone who has an opposing viewpoint and is actually willing to listen instead of just going “EVOLUTION IS THE DEVIL AND THE BIBLE SAYS SO” or eyes glaze over which is what I usually run into when I even start mentioning this…

Blanket statements make me twitch and twinge in pain….

Can you tell me which breed is more fit or physically weaker when you are comparing a Clydesdale or other European draft horse versus an Arabian? Don’t take any personal breed preference or consider what you use or think an ideal horse should be used for into account. Both breeds are incredibly athletic and strong so unless you look at the context and environment in which the two breeds are in I don’t think anyone could make the judgment which is fitter or physically weaker than another. Each breed has its own strengths. For pure power the drafts have the Arabian beat, but endurance, agility and athleticism the Arabians have the advantage. Each breed arose in different environments for different purposes. Drafts have broad barrels and have chunkier bodies to conserve heat, heavy coats for winter, etc, all for colder climates and size, strength and gentle personality to be used by all members of the family for plowing, hauling loads, etc. because you can’t have essentially a temperamental tractor when you NEED to get those crops planted if you are going to get a harvest that season. Arabians are finer built with a proportionally larger surface area to allow cooling in hot climates and much smaller since their primary purpose was a fast, spirited riding horse. Both breeds are great, both survive just fine in a barn but due to the environment they were bred in they have different traits that make them better suited for particular conditions and uses. If you say environment doesn’t matter (and I will disagree till the end that it does) and you want to compare it to the natural form of the horse…what natural form are you using? Basically all domestic horses ancestors are extinct. I believe Przewalski's Horse is the only one left which is smaller like the Arabian but stocky like the drafts. Other than that all wild horses are just from feral domestic stock so back to the question what is the natural form domestic breeds were derived from originally? What about using a very early horse ancestor which was just a few feet tall? The closest breed to that is a Fallabella and those are just pure novelty although very cute in my opinion (opinion mind you) so that would imply any horse you can ride would be inferior compared to the original natural form of the horse.

What about comparing the fitness of different species? Who is to decide which large wild cat is the “natural form” when comparing tigers, cheetah, leopards, puma? You'd have to use their most recent shared common ancestor and how would you determine fitness from bones to see if the new species is more fit or less than their extinct ancestor?

Context is always important and in this case the context is environment and ability to reproduce in that one particular environment. The fitness of the exact same individual can change just by changing the environment so even with the same individual there is no one blanket fitness score without the environmental component.

Sure with some breeds that seem obscenely deformed like the pug, Persian, etc you think blanket statements may apply that they are physically weaker but what about the majority of the breeds which are more along the lines of degrees of variation and not as obviously weird?

I agree, squished noses make for weaker breeds IF all humans disappeared tomorrow and all breeds interbred. But in that case natural selection would remove deleterious traits which humans originally selected for artificially. But in the current domestic environment pugs live and breed just fine..sure they have additional health concerns which affect their physical condition but their fitness is no less than your average mutt and often higher.

I want a dog that is athletic and active so I'm looking for a different breed than someone who wants a nice quiet companion and would love a pug. Different environments makes different breeds more suited for that set of conditions. If I got a pug and went for a "short" little jog I'd probably kill the poor thing or have it slumped in a wheezing mess while if my great aunt got a border collie or husky that would not end well at all either...I'd foresee that situation ending in the dog dragging them both into traffic killing them both or getting sent to the pound and put down for being psycho when all it really needed was a more active environment to burn off and focus that energy.
