Can't tell if you're joking or serious.
In the latter case, the first humans (H. Habilis) had about 1/2 of H. Sapiens brain to work with, and a much smaller fraction of neocortex.
If that doesn't satisfy you, let's say I was speaking about some sort of human ancestor before that, which would have been about as dumb as chimps, unless you require proof of their dumbness as well.
- Zanni 3y agoNot your original objector, but ... I was willing to accept that early humans are dumb, but your explanation relies on evolution and not social interaction.
- Andrex 3y agoExactly. Humans didn't learn their way out of only having half a brain, more the opposite.
- junofan 3y agoWe know their brains didn’t grow much after birth, unlike humans, which also suggests faster maturity akin to living apes and likely less social support for extended adolescence.
- jojobas 3y agoHumans didn't evolve knowledge, they evolved the capacity to get more knowledge. All the new knowledge they got they figured out from the environment.
- theduder99 3y agoHard to imagine anyone believes these prehuman theories. Just look at the h hablis wiki page to see 90% of it is pure speculation and debated.
