Lets break down the three clains in reverse order:

1. Are there primitive societies of hunter-gatherer that are not self aware, as in they don't pass neurological test that measure this?

2. From a evolutionary perspective what is the advantage of this sexual dimorphism and given that this advantage exists why did this advantage disappear afterwards and become present in both sexes. Are there any other traits where woman are shown to have larger divergence. I thought men where the "weak" sex in this regard.

3. If consciousness is recent then how do you explain conscious trails and self awareness in lower primates, is this also a case of convergent evolution?
