Early humans were social and initially scavenged, before becoming active hunters. The need to communicate and hunt prey efficiently in a new, fluctuating environment (where the locations of resources need to be memorized and told) may have driven the expansion of the brain from 2 to 0.8 Ma.

However, the specimens were found in a stratigraphic unit dating to 1.95–1.78 million years ago, whereas the earliest Homo fossils at the time dated to 2.33 million years ago (H. habilis from Hadar, Ethiopia).
