Re: Could the theory of Darwinian evolution be mistaken?

So. Quite a lot has been added and corrected since 1860. Darwin laid the foundation; he never claimed it was a finished body of knowledge, and neither has anyone else. But 'Can't turn dogs into cats' is right down there with "How come there are still monkeys?" That shows you haven't grasped enough basics to make an argument.
(I'm counting 2 years for canine and 20 years for human breeding maturity. For most of the time period, both species were probably reproducing at an earlier age; closer to 15 years per human generative cycle - which makes it even more: maybe 357,000 generations. Probably 160,000 since the earliest identifiable human. That's plenty of scope for cumulative changes. Consider: we've only had 250 generations since Noah.)
Even if you take the human evolutionary tree transitional forms between the different human species are absent and you have very rapid speciation taking place in less than 6 million years.How do you mean transitional forms between human species are absent? http://humanorigins.si.edu/evidence/human-fossils You do understand there's not supposed to be any bridge between concurrently existing types - only common ancestors of divergent types. 6,000,000 years is hardly an eye-blink! All this http://popchartlab.com/products/the-diagram-of-dogs happened in the less than 10,000 years that humans have been breeding dogs. Since canines - though not modern style dogs - may have been associated with humans for as much as 32,000 years, I'm allowing that the domestic canine species must have undergone some modifications during the whole of that association: that's 16-20,000 generations of dogs altogether; no more than 6,000 generations of purposeful breeding. Why do you consider those changes in hominid skull shape, in a variety of environments, over 350,000 generations, as very rapid?
