The larger brains of early Homo babies meant that they needed a longer period of development and maturation outside of the womb, resulting in a longer period of dependency on their parents. This is supported by the fact that Homo babies had a higher ratio of brain to body size than earlier hominids, indicating that their brains were larger in proportion to their bodies at birth. This longer period of dependency likely provided a selective advantage as it allowed for greater social learning and cultural transmission from parent to child.
