Do you actually think a species giving birth to a different species is something "Darwinism" predicts, or did I just misread an example you were trying to make? Have you ever actually defined what your opposing stance is yet on all this?
No, I was pointing out Darwinism is a gradual and defined process with specific predictions, and on this thread, particularly about the evolution and development of the genomes of living creatures. Evolution predicts a slow accumulation of genes as a result of a slow process of mutations that survive in the mutated creatures via natural selection. The further back in time, in general, you should see simpler genomes and less types of genes. The last common ancestor should have very few gene types compared to living biota (all living creatures) today.
The problem is the evidence, assuming evolution in the first, place is the exact opposite.
