abstract
  • The Dragons of Eden: Speculations on the Evolution of Human Intelligence is a Pulitzer prize winning 1977 book by Carl Sagan. In it, he combines the fields of anthropology, evolutionary biology, psychology, and computer science to give a well balanced perspective of how human intelligence evolved. One of the main issues featured in the book is the search for a quantitative way of measuring intelligence. Sagan shows that the brain to body mass ratio is an extremely good indicator, with humans having the highest and dolphins second (pp.38–40, hardback ed.). It does break down, however, at the extremely small end of the scale. Because a certain minimum size is needed to sustain life, smaller creatures (ants in particular) place disproportionally high on the list. Other topics mentioned include the evolution of the brain (with emphasis on the function of the neocortex in humans), the evolutionary purpose of sleep and dreams, demonstration of sign language abilities by chimps and the purpose of mankind's innate fears and myths. The title "The Dragons of Eden" refers to man's early struggle for survival in the face of predators, and how fear of reptiles may have led to cultural beliefs and myths about dragons and snakes.
