Survival of the Fattest: The Key to Human Brain Evolution was written by Stephen C. Cunnane. The book outlines why fat babies are important to human brain evolution and the ecological circumstances that allowed for fat babies to evolve. Cunnane details the specific nutrients that are important for human brain growth and function and explains the ways in which they work. Cunnane also presents a theory called the Shore-Based Scenario to explain where ancient hominids obtained these nutrients. The book has implications for many fields such as: Neurophysiology, Biological Anthroplogy, Paleoanthropology, Paleoecology.
Synopsis
The Human Brain
Cunnane begins by explaining the similarities of all animal brains. Hox genes control the traits of brains for almost all animal species. Similar to all primates, humans don’t show a specific genetic advantage for brain growth while in the early stages of embryonic development.

The newborn infant brain uses about 74% of the energy consumed by the entire body.
