The finds so far paint the picture of a strong creature with strong jaws and a distinctive parietal crest, which is also very pronounced in gorillas. In other respects he resembled humans. Now there is new evidence of the species’ dexterity: 1.5 million-year-old fossils were discovered in Kenya that can be assigned to the robust relative.
