    Lumping and splitting remind me of assimilation and accommodation, two concepts developed by a pioneer in the study of child development, Jean Piaget, who is most well known for his theory of how children learn. Assimilation refers to making associations between something new and that which is already known. For example, imagine a child who is familiar with dogs, but has not seen a horse before. If he sees a horse for the first time and says itís a dog, the child is assimilating (Lumping. The taxonomist sees a new form of a plant and puts it in an existing species.). Accommodation refers to changing what is known when oneís existing knowledge is insufficient for solving a problem (Splitting. If the existing species are insufficient, the taxonomist creates a new one.). Thus, new situations are assimilated into old ideas, and new ideas are created to accommodate new experiences. There has to be a balance between assimilation and accommodation. If there is too much assimilation, nothing new is learned. If thereís too much accommodation, thereís too much to remember

    Taxonomists have to make decisions about lumping or splitting all the time. I donít know whether they should be recognized for regularly performing fundamental functions of learning or whether they just havenít left childhood. (I hope taxonomists will assimilate this as a joke.)

    I think I'm a splitter. Everything has its own distinct differences that seperate them.

    I'm a splitter when things need to be slpit, and a lumper when things need to be lumped.
    for example... I'm a lumper a lot of the time because I think it's ridiculous to say something's a new species just because EVERY SINGLE THING is the same EXCEPT that there's an extra cell on it's leaves (ok ok, I'm exaggerating :P but you get the point)
    and I'd be a splitter with those kinds of things that there are 10000 different ways it can look.
    for example.... there are many plants that are "extreamly varibale" that may have lobed leaves, some with 3 lobes, others with 5, some with no lobes, some with spikes, etc....
    and yet there are other plants that you literally have to look under a microscope to tell appart (or worse yet.. DNA testing)

    isn't that just ridiculous?

    They say if you play a Microsoft CD backwards, you hear satanic messages. Thats nothing, cause if you play it forwards, it installs Windows.

    But DNA testing is the best way to determin a plants relations to others. Altough they may look similar, it means nothin if they are not closly related.

    Take the olive warbler


    The olive warbler is the sole member of the family Peucedramidae. It was traditionally considerd a member of the Parulidae, or New World Warblers.


    New world warbler

    However, recent studies of its breeding biology, morphology, and DNA indicate that it is not very closely related to them. Infact, it was so distinct that it did not fit into any known family, and thus one was created for it.
    that makes no logic

    Splitter mainly(recognize all the forms), however, I would be considered a lumper as far as "Lets create a new genus" is concerned.
    1 Nxventrata

    D. muscipula & D. muscipula 'Red Dragon'(barely)

    Sarracenia leucophylla(seedling)

    S. purpurea and Drosera filiformis filiformis/ intermedia seeds waiting to sprout.

    Drosera capensis

    Lumping is easier, but sometimes splitting is necessary
