#1 The fundamental truth of evolution is that individuals who are best able to acquire food and avoid predation or disease are the most likely to survive and pass on their genes.

#2 The brain and body’s abilities to endure periods of food deprivation are adaptations that allowed our ancestors to survive and pass on their genes. These include the creativity that allows us to design and manufacture tools for hunting, the organization of societies via governments and religions, and the tolerance of bitter-tasting phytochemicals in plants.

#3 The human brain was sculpted by evolutionary processes based on whether a brain structure or type of nerve cell improved success in food acquisition or reproduction. The ability to navigate accurately while moving through complex environments is fundamental for success in food acquisition.

#4 The size of the prefrontal cortex is much bigger in humans than in other animals. It is believed that the expansion of the prefrontal cortex in primates allowed them to make critical decisions that increased their efficiency in foraging for fruits and nuts.
