Diversity

Submitted by eharnett on Sat, 09/29/2007 - 11:57am.
I thought it was intersting that, after our discussion on Friday, we "determined" that there is not random variation but rather nested clumps of diversity. Because there are so many similarities between organisms at different levels and scales, it seems like this would make sense. However, according to Darwins Theory of "survival of the fittest", shouldn't part of evolution be random variation? Along the way there must have been some sort of variation that allowed for certain organisms to be "fitter" and reproduce more successfully than others and therefore allow for their genes to be passed on. Maybe I am thinking about this the wrong way, but that was what puzzled me after class-there must of been some type of random variation.
