think about this...
If we are able to selectively breed dogs and create a vast difference in breeds through selectivity in such a short time, how is it so unbelievable to postulate that over 300 million years the environment could shape and isolate traits to create gradual phenotypic differences which after that much time would culminate into our different phyla and millions of characterized species.
don't think thats too much of a crap shoot.
It's a possibility but it would take that long of a time for the enviromental evolution to have an effect on their genetic level.

which goes to prove the point that little genetic change is required to see huge visual change in the organism.
so dogs having a common ancestor with bears and seals and racoons doesn't seem so far fetched.

Science has been around say 500 years? Why are people trying to explain the world using religious texts written thousands of years ago? Looks really idiotic on their part.

All the difference in humanity is 1/10th of 1%.

fair enough, he's using the argument of semantics now. Sure its a different species. but what is a different specie? A donkey is considered a different specie then a horse. A leopard is considered a different specie then a chetah. This is because there is genetic variety AND they chose not to mate with eachother. To think that over time organisms do not change is perposterous. Notice how that guy went through all these positive scientific facts and neglected specific explanations for things that are known. For instance gene expression. Enough mutations can cause new gene expressions which over time would lead to what we call speciation.
How can we really observe siginificant "natural selection" if we have only really been observing it for hundreds of years? All we have are fossil records and DNA records which create a history book and timeline. This is the hard evidence. Also gene expression micro evolution and selective breeding is the physical process. This can also be observed.
Notice how at the end as well he mentions how darwins ideas lead to racism and haeckels ideas were disproven and again he mentions that evolution does not occur.
He neglected to mention atavism and vestigials as well, one of the strongest arguments for evolution.

you have to also consider that genes aren't as isolated for humans since our breeding isn't very selective, our population isn't limited (its actually increasing exponentially) and all though random mutations occur, they do not cause segregation in our species. ALSO we've only been around for 200,000 years since our last divergence.
All this will cause for a lack of amplification in genes. Humans born with tails will not continue to breed with other humans born with tails. Tall people don't necessarily marry tall people. Whites don't always marry whites and certain phenotypes do not dominate other phenotypes in our societies, generally speaking.
So its difficult to see a course of evolution occur with humans, but it is obviously possible and it may occur in the far future.
