There was a study a while back in which a selection of gender-intended children's toys were distributed to chimpanzees. All of the chimpanzees, male and female, were initially interested in the "boy's toys" (toy trucks). But only the female chimpanzees were interested in the toy dolls, and the female chimpanzees continued to be interested in the toy dolls for considerably longer than either was interested in the toy trucks.
Interesting. I remember Gad Saad talking about such a study. Didn't know the specifics.
It seems like for each genus there is a "normal" ratio of brain mass to body mass, but if one species of the genus has even a slightly greater percentage of brain above that normal ratio, it becomes an amazing "genius." Crows and certain other black birds, for instance, have only a slightly greater brain to body mass ratio compared to pigeons...but are incredibly more intelligent, and more intelligent than many animals with much greater absolute brain mass.
Yeah. Men and women are roughly equal in intelligence. Men have a slightly larger brain and skull, yet women have a slightly higher brain to body mass ratio. I do find it fascinating how a brain to body mass ratio compared to sheer brain size can contribute to intelligence.
