no male and female brain types – Mind Hacks

Scientists today think that above all else, the first stone tools began humanity’s Age of Meat. Meat is a nutrient-dense food and is highly prized among wild chimpanzees that use it as a , and male chimps have used it as payment for sex. The human brain is more than three times the size of a chimpanzee’s, but recent research suggests that the human brain’s size is , and great ape brains seem relatively small because their bodies became relatively large, possibly due to sexual selection that resulted from vying for mates. Humans developed relatively larger brains and relatively smaller and weaker bodies, which was ; something had to give. Protohumans began relying on brains more than brawn. The studies of brain size, encephalization, neocortex function, intelligence, and their relationships are in their infancy. The current . Larger brains were needed for navigating increasing social complexity, and not only the number of individuals in a society, but the sophistication of interactions. It is also argued that smarter brains allowed for greater social complexity, in another possible instance of mutually reinforcing positive feedbacks. Societies can perform tasks that individuals cannot. Those engage in wars and revolutions. They can procure a food source and secure the territory, which creates the energetic means for developing a society. Tool-making may have been a bonus of that enlarged brain needed for social navigation, and walking bipedally coincidentally provided new opportunities for hands. , and all proposed dynamics may have had their influences. , about 10 times the energy needs of equivalent muscle mass, and primates cannot consciously turn their brains off any more than they can turn their livers off. Few studies have been performed on the relationships between energy, brains, and sleep, but a recent one found that sleep seems to be .

Prenatal hormones and sexual orientation - Wikipedia

N2 - Sex differences in empathizing with others and systemizing the abstract rules that govern the operation of things and the natural world have been proposed as the core, essential differences between men and women. We evaluate this assertion in the context of Darwin's (1871) sexual selection and specifically test the hypothesis that the systemizing measure captures interest in evolutionarily novel occupational niches associated with interests in science, technology, engineering, and mathematics (STEM). Young adults (n=233, 149 male) completed the Empathizing Quotient (EQ), the Systemizing Quotient (SQ) and the RIASEC Personality Type Inventory to assess six career interest groups. Sex differences were found on the EQ, SQ, Investigative interests and interest in things, a subset of items from the Realistic scale. Mediation analyses revealed that occupational interests partially mediated the relation between sex and SQ scores, whereas controlling for Investigative interests increased the sex difference in EQ scores. These results provide partial support for the hypothesis and suggest SQ captures, in part, occupational interests in evolutionarily recent STEM fields.

I think it very reasonable to believe that relatively sophisticated tool use among humanity’s ancestors predates, perhaps by several million years, those stone tools dated to 3.4-3.3 mya. Tools may be hundreds of millions of years old, and , , , and use tools today. The protohuman equivalent of (although it may have been a female) discovered how to bang two rocks together to create a hard edge used for cutting, perhaps with a little inventor’s serendipity. It may not be possible to overstate the significance of that invention. More than a million years of free hands, due to australopithecine bipedal posture, probably led to the most significant tool-making event in Earth’s history to that time. The shortening fingers and lengthening thumbs of australopithecines led to more dexterity, and in training today’s great apes to make stone tools, their relative lack of dexterity has been noted as an impediment. Also, the is linked with neurological changes, from the hands to the brain, as early protohumans took tool-making to a new level, in .

Girl Brain, Boy Brain? - Scientific American

Goldstein describes another trait, the willingness to work in hierarchies, a characteristic of which is willingness to follow orders of members of higher rank.xiv John Horgan, in his book The End of War calls this trait “docility.”xv Goldstein, reviewing studies on primate hierarchies, says that as a general rule, “human males may be more hierarchical—oriented towards competition and status—whereas females are more empathetic, although with a 'great deal of plasticity' in gender roles.”xvi

This is why a world with fully empowered women sharing with men in decisions regarding war would be more socially stable: because of a female's unavoidable and costly commitment to her offspring, basic human female biological priorities are different from those of males.
