Identify the statements that are true about the evolution of brain size in the genus Homo

true statements Since the first appearance of the genus Homo, the brain size of some species increased while others maintain a smaller brain size. Increase in brain size can only be supported with an increase in food quality and more calories. Larger brain size led to the need for rotational birth. false statements Increase in brain size corresponded to increase in body size. Since the first appearance of the genus Homo, brain sizes only increased.
