When our distant relatives starting walking upright, it would start to lead to a bigger brain. Nerves, muscle control, and dexterity would also have to become more complex to the legs down to the feet. As monkeys that primarily use their arms that are dominant in all they do. Being upright means using all limbs in conjunction and coordinating together at the same time, unlike using the arms predominantly and legs playing a secondary less active role.

No brain, no pain. According to Norm, alcohol kills off slower functioning brain cells making the faster functioning brain cells not have to wait around for the slower brain cells to catch up. That is why alcohol helps our brain.

Apparently brain size diminishes when an animal can be less aggressive. A kill with a bow and arrow is less aggressive than close combat kills. After we domesticated ourselves we could afford to be less aggressive

Certainly a major neocortical expansion pressure was the ratcheting ever upward via whittling away of lesser and compounding of the greater intellectual capacities to out think an equally cunning foe in combat.

Still much speculation about the motivation for human anatomical development and where it all came from
