I have doubts about the Galapagos finches being a good example of animal speciation, and so I am turning to you all to tell me what other examples there are. This thread is not to challenge the concept of speciation or its validity; I am looking for solid and vivid examples from the animal kingdom that can be used to exemplify this process to a skeptic.
I am also wondering if all the experiments with fruit flies produced a new species or a new genus (with all those many generations, and access to induced genetic mutation). ?
