And his theory involved a lot of contributing factors, one of them being climate change.

And the theory was that as the rainforest receded into grasslands, you get more undulate animals and they leave behind poop.

and that these lower primates find these mushrooms that are growing on the poop and they experiment with them.

And that the ones that did increased visual acuity, they became more amorous, they were more likely to breed.

more creative, the ability to form sentences, glossolalia, associate sounds with objects and concepts, and that this is probably how language formed among humans.

And Terrence's connection to that

When you look at the timeline of when this was happening, when we know this was happening, which coincides with the growth of the human brain, which over a period of 2 million years doubled in size, which is pretty phenomenal.

So in the inner limits, what was the amount of growth in 200,000 years?

200,000 years, 50%.

200,000 years ago.

Oh, so.

But like Homo sapiens in this form have existed more than 200,000 years though, right?

No.

No.

I was under the impression it was more than 300,000 years ago.

Well, he does such a brilliant job of explaining the mechanism behind the stone ape theory.

You know, like Terrence had a great way of talking.

He was so interesting to listen to and had these wonderful ideas.

But Dennis is like much more of a hardcore scientist.

Yeah, Carey Mullis.
