Here's a thought. Who milked the first cow? And what the

When he said, "Some say," I thought for sure he was going to continue with something that ended with, "All we know for sure is, they call him The Stig."

Hah, I heard "insect that can disguise himself as a Stig" :D

Humans are still evolving, we've just changed the game a bit. More than likely we will eventually begin manipulating our own evolution by altering genes directly but that is probably a ways off yet though certainly foreseeable. There are people around the world with mutation so incredible that if we put them all together we would essentially have a "super-human" with hyper dense bones and muscles, resilience to even the most devastating diseases, ability to see farther into each end of the light spectrum, and many others. All kinds of things that natural evolution has already introduced into our genome. All that is needed is to find out which genes are responsible in these individuals/families and see if they can be made compatible with others. I know how all this might sound but science fiction was so last decade, the more we learn about the universe we live in the more the word "impossible" is becoming irrelevant.

I feel vaguely offended by the premise that my parents have done the deed. My father was a sperm donor, so he and my mother never did... that bit.

The x-factor remark at the end, almost wet myself :D Great stuff!

Wow. Just found this channel.Great knowledge packed in a small and easily understood form! Thanks for this and for the always so witty humor of James May

No better way to explain things than a british gentelman

Would we overpopulate out into space?

thanks that clears a lot.

Very interesting. Thank you!

Why do Humans think about things and do not just follow instincts?

"assuming we can find a willing partner"

The most interesting episode yet!!!

I love the part with the primitive dude with a rock axe and the old-days smart gentleman. XDDD when the other throws the hammer... LOL!

I agree with Sir David Attenborough that human evolution has effectively stopped. I would go even further by saying that I believe we are working to reverse it. Not only are less intelligent people more likely to reproduce, many otherwise intelligent people actively seeking out less intelligent mates because a hopeful failure is more interesting than a boring success.

Your lactose comment is incorrect on a global scale. 95 percent of European people can digest lactose but somewhere down to 10 percent of African populations can and about 35 percent of Asians are lactose tolerant.

Thank you for making that very important point : )

This is fascinating to think about
