Portal, then the evolutionary theory from Darwin's time until now has gone from "bunk" to "modified" how many times?
If I remember correctly (read origin of species in 10th grade) Darwin didn't say evolution lead to the very beginning, the first cell, or anything like that. He presented it as a theory about existing species, and then the academic community built on.
Darwin's points leading up to evolution have been confirmed - we see genetic drift, we see natural selection, and we see microevolution. We see it in mimicry of butterflies, we see it in the domestication of dogs from the grey wolf or somthing like it (all dog/wolf/dingo/cyotes can interbreed and produce fertile offspring, mind you.) We see it in bacteria adapting to anitbiotics.
Definition of species= any animal that can mate and produce fertile offspring with any other animal. (So, not a mule.)
However, we have not replicated macroevolution, or, when one species becomes another speices ( have adapted so far from each other they can no longer interbreed but once could. ) The fossil record is supposed to prove this - because many animals come from a common ancestor who cannot breed with each other - probably because of plate movement and other geographically separating conditions). But I'm am with you - a little skeptical until it can be reproduced under lab conditions. The problem with this is it could take longer than humans have been on the planet for, so they are trying to work with species that mate and breed extremely fast. I am not up to date on these experiments.
So, please do not discard evolution as a way to understand genetic drift, etc. If you like, you can simply say "I believe in micro-evolution." If you do and sound intelligent :wink: . What do you think about the fossil record? It seems to hold up to me, but again, lab experiments are more straightforward as evidence.
So, technically it has never been modified or bunked, but macroevolution isn't in the "fact" bag yet.
