ABSTRACT
Since the thema of this book is mammalian brain to human brain, I will concentrate on the evolutionary story of the primate brain. The earliest fossils of the order of Primates are represented by teeth as early as 80 myBP (million years before present) (Stebbins, 1982). Small primates are recognized as tree-livers from 65 to 40 myBP. Modern descendants of these prosimians are probably treeshrews.
