A trend in brain evolution according to a study done with mice, chickens, monkeys and apes concluded that more evolved species tend to preserve the structures responsible for basic behaviors. A long term human study comparing the human brain to the primitive brain found that the modern human brain contains the primitive hindbrain region ...
The human brain has evolved around the metabolic, environmental, and social needs that the species has dealt with throughout its existence. As hominid species evolved with increased brain size and processing power, the overall metabolic need increased. Compared to chimpanzees, humans consume more calories from animals than from plants.
Studies of the brain began during ancient Egyptian times but studies in the field of evolutionary neuroscience began after the publication of Darwin's On the Origin of Species in 1859. At that time, brain evolution was largely viewed at the time in relation to the incorrect scala naturae. Phylogeny and the evolution of the brain were still ...
The expensive tissue hypothesis (ETH) relates brain and gut size in evolution (specifically in human evolution).It suggests that in order for an organism to evolve a large brain without a significant increase in basal metabolic rate (as seen in humans), the organism must use less energy on other expensive tissues; the paper introducing the ETH suggests that in humans, this was achieved by ...
The stoned ape theory is a controversial hypothesis first proposed by American ethnobotanist and mystic Terence McKenna in his 1992 book Food of the Gods. [ 1 ] [ 2 ] The idea claims that the cognitive revolution was caused by the addition of psilocybin mushrooms , specifically the mushroom Psilocybe cubensis , into the human diet [ 3 ] around ...
The "paleomammalian" trait of parental care of offspring is widespread in birds and occurs in some fishes as well. Thus, like the basal ganglia, the evolution of these systems presumably dates to a common vertebrate ancestor. [13] [16] The ratio of the brain mass devoted to the pallium increase in parallel in various vertebrates' taxa [17]

He also suggested that the brain, not the heart, was the organ that ruled the body (what Stoics would call the hegemonikon) and that the senses were dependent on the brain. According to ancient authorities, Alcmaeon believed the power of the brain to synthesize sensations made it also the seat of memories and thought. [2]
