Surely you jest! Chimps have about 450cc of brain capacity, humans
have about 1350cc. Chimps mature at 4 years, are sexually mature at 8
years, and die about 40 years, humans are sexually mature at about 15
years (with a dimorphism between male and female) have menopause 45-50
and die at 78 years. How's that for starters. Most of these changes
seem to have occurred as a result of changes in a few regulatory genes
(humans resemble immature chimps much more so than they resemble adult
ones - a case of neotony).
