how can you say that sexual selection does not affect humans, atleast in this culture and in many western cultures. We SELECT our own mates, we date them we go through this rigorous mating ritual to see if they are the person that we want to mate with. Also if after sometime we decided we dont like that mate we go and find a new one. Also our ability to control reproduction also plays a factor since often times people will be with other "mates" for reasons other than sexual reproduction.Originally Posted by [b
although i will agree most, but not all, "natural" selection has been removed and been replaced with human created artifical selection. by artificial i mean the ability to deal with new industrial biproducts that are harmful to humans. some people can deal with dangerous chemicals enter the body in small doses without minimal effect on their reproductive capabilities, while other will become unable to reproduce or have weak offspring. although the results of this is something that is not yet know it is an area of new study that many bioanthropologists are exploring. and there is still some natural selection taking place with the example of viruses and bacteria that are not treatable yet some people seem to resist the diseases while other succomb quickly.
