works\ Evolving Brains [1998]
Detail: He studied brain evolution. Brains allow animals to account for environment variations in space and time and make appropriate responses. More advanced brains allow wider spaces and longer times. Brains require much energy and are in animals that can find more and/or better food at higher rate. Complex brains require longer time to develop. Family and group structures were necessary for humans to have advanced brains.
Brains can sense water, food, sexual partners, shelter, and safe locations, as well as predators and dangerous locations. Brains can assign priorities to input. Brains can perform activities to get food or water, reproduce, gain shelter and safe locations, and avoid predators and dangerous locations. Brains can remember input and output.
Brains are more complex if environmental niche is more variable. Animals use larger energy amounts, because warm-blooded. Water, food, sexual partners, shelter, and safe locations are scarcer and predators and dangerous locations are more numerous. Maximize age is higher.
