Description Summary

H. rudolfensis was originally attached to the species H. habilis, but further subsequent studies indicated that it belonged to a different species. It is an almost complete skull with a brain size of about 700cc.

Middle Pleistocene

Climate swings became more extreme during this period, and there was also more significant adaptive radiation of animal life. Our lineage also became more diverse with more than 10 known hominin species known across the world from this time. Brain sizes in hominins began to get larger. At the same time, human technologies became more diverse and took more planning and skill to make. This ability to plan along with improved locomotion enabled hominins to leave Africa for the first time.
