a: Homo habilis brain grew 50 percent from 600 to 900 cubic cm. Human brain on average 1200. The argument for intelligence was about collaboration btw males as a larger social body. Thank u!!!
charles brown : an argument for selection for larger brain is larger brains are better at the language and culture of courting so had more fertile matings ; collaboration between females and males is more important to passing on big brain genes to future generations than collaboration among males. Differential fertility is more important in determining fitness than differential mortality.
