Question

What is the size of the brain of Australopithecines?

Answer 1

Compared to the modern and extinct great apes, A. afarensis has reduced canines and molars, although they are still relatively larger than in modern humans. A. afarensis also has a relatively small brain size (about 380–430 cm3) and a prognathic face (i.e. a face with forward-projecting jaws).
