Human Brain Evolution
Description
Reviews / Votes
"This is an ideal book for Graduate students, post docs,research scientists in Physical/ Biological Anthropology, HumanBiology, Archaeology, Nutrition, Cognitive Science, Neurosciences.It is also an excellent selection for a grad student discussionseminar." (Human Evolution, 1 March 2013) "This volume...is a puissant move away from the heavy,earthbound view of hominid evolution and a move toward a greateremphasis upon the role of water and waterways in hominiddevelopment, survival, and diversification" (Phillip Tobias,Foreward, Human Brain Evolution)More details
