What are the selective pressure inherent in living in complex social environments? According to one view, the answer to this is also the reason why people have large brains. What is the dominate consensus to the question?

google social brain hypothesis.


This idea would explain why people are shallow when it comes to selecting mates, because culture is always changing.

@TuringEquivalent,
Large brains developed because we began manupulating our hands to build tools. Elephants and octopi also have big brains because more brain power is required for the elephant to manipulate its long all-purpose nose and the octopus those tentacles. Dolphins have large brains as well and their hunting techniques may account for their large brains.

The early hominids walked upright but their brains only began to grow larger with tool making.

Are you incapable of learning? The dominate hypothesis is the social brain hypothesis. The large brain is due to being in a complex social society.

@TuringEquivalent,
You are worrying about being in the lower strata of society to which you belong.

Bees and ants also socialize.

So, what about my socio-economic status?

I don` t know if bees, and ants "socialize". "social brain bypothesis" is not about socializing, you ******* bitch.
