Australopithecus Afarensis
Likewise, Australopithecus afarensis, the hominin most likely responsible for the famous Laetoli footprints (Leakey 1987), probably spent a good proportion of the day moving arboreally as well as bipedally (Stern and Susman 1983).

It is also consistent with the hypothesis that P. robustus is more closely related to Homo than to A. africanus.

A Dietary Shift from Homo Habilis to Homo Erectus was caused by the invention of stone tools by Homo Erectus enabling more meat eating - more protein and concentrated calories and nutrients - for taller bigger skeletons....So by 2 million years ago the Homo lineage was dependent on technology.
So the increase in brain size of Homo Erectus also required cooperative child raising. The first human growth pattern based on teeth is from around 1 million years ago!
Neanderthals had less efficient thermo-regulation of body size, thereby requiring more calories to keep warm.
