Lex Fridman had an interesting biological anthropologist who worked with Goodall studying Chimpanzees who had some interesting ideas about the divergence of humans from our shared ancestor with Chimpanzees[0], namely the excising of reactively hyper-violent males, e.g. alpha males.

I watched the first 15 minutes of this it was really interesting. The video is quite long, where does he discuss exciting hyper violent males?

Fridman puts timestamps for topics in his pods within the description, so just click "Show More" there to reveal em. But you're looking for this[0]

Oh, certainly I mean excise and not excite

If true, would that imply that humans were at some Goldilocks zone between the Chimpanzees and the Bonobos, then?

We branched from a shared ancestor about 5 million years ago, so before there was a distinction between Chimpanzee and Bonobo around 2 million years ago IIUC.

The chimp memory test video is really worth seeing: https://youtu.be/aAIGVT3N7B0?t=109.

That's impressive.

Nice quote:

> During the six decades since that first sighting in Gombe, Tanzania, many further examples of tool manufacture and use among chimpanzees have been discovered. It has become clear that each chimpanzee community has its own repertoire of tools and associated behaviors.

Michael Stevens from the Vsauce YouTube channel visited Tetsuro Matsuzawa, the author of this article. He competed against Ai at the masked numbers test and was utterly outmatched by the chimpanzee. The speed at which she taps the numbers after seeing them only for a fraction of a second is stunning.

The whole video is worth a watch, but try this link if you want to skip to the match between human and chimpanzee: https://youtu.be/ktkjUjcZid0?t=739
