Extract of sample

These early hominids experienced the interpreted environmental changes. These changes, however, probably had little negative affect on this hominid. In fact, the adaptations that permitted Homo erectus to leave Africa were most likely well suited to the open woodland environments subsequently encountered. These adaptations include larger body size compared to earlier hominids, bipedality, linear body proportions, and a more sophisticated tool kit (Spencer, 1997).

Others (Anton et al., 2002) have suggested that the maintenance of this large body size, as well as increased brain size, may have resulted from greater nutritional dependence on animal fat and protein.
