He's a doctor, but big deal. I'm in medicine at the moment. I can tell you that medicine (for the most part) avoids the study of evolution - when it comes to credentials, we're the same.
The thing is, the problem is not with his human biology, it's with his evolutionary biology. The guy clearly doesn't understand it, or even understand science. He even trots out the 'it's just a theory' at one point.
If you want, I'll show you. Want an example?
1. He calls a chimp a monkey. He then trots off examples of how we're different to the average monkey, telling us that's why we're so different to chimps.
For example, he uses the vitaman c gene wrong. He says that it's broken in us, and not in monkeys, implieng that we are different. Suprise, it's also broken in chimpanzees, in exactly the same place, but of course.. he doesn't tell you that.
Then he makes a really big deal about tails. Of course, he doesn't tell you that no apes have tails. Nor does he tell you that humans are sometimes born with tails. He actually has the gall to tell us that this is a big reason why we are different to chimpanzees! Even though chimpanzees don't have frickan tails!
That's just one example. It's a lie, pure and simple.
