I'm just openly questioning the theory. I know that is unsettling for some. I hope none of your students question it either, based on your response.

I'm going through your list now. The first two are not speciation as they talk specifically about interbreeding between the lower and upper pool guppies. I do plan to get book, "The Beak of the Finch" they site though to learn more.

Its going to take time to read the rest.

Your definition helps me with the a better understanding of evolution: "heritable changes...spread over many generations."

Using that definition, the plant polyploid examples don't fit evolution. First of all, polyploid is just the duplication of the current genes, not creation of new ones or new combinations. The redundancy in the genes may result in minor changes in traits as genes cancel each other out, but that process can hardly be used to support evolution since it results in no new "heritable changes" to the genetic code. Your not going to get a tree eventually if you keep duplicating the same genetic code over and over. All you are going to get is the same flower with different genes activated. Second, it happens immediately, not "over many generations."

Thank you for your help. I will spend some time reading these. Hopefully what I am looking for is here.
