In this groundbreaking look at the evolution of our brains, eminent neuroscientists Gary Lynch and Richard Granger uncover the mysteries of the outsize intelligence of our ancestors, who had bigger brains than humans living today. Weaving together history, science, and the latest theories of artificial intelligence, Lynch and Granger demystify the complexities of our brains, and show us how our memory, cognition, and intelligence actually function, as well as what mechanisms in the brain can potentially be enhanced, improving on the current design. Author of "The Emotional Brain," Joseph LeDoux praised it as "provocative and fascinating," and, writing in the "New Scientist, " Willian Calvin called it "a popular account of how brains enlarge, in both evolutionary and developmental terms" and "a much needed book."
