Thus, it made them better hunters because they could hunt from a distance. Most teeth were still in their sockets. The nickname for Homo Ergaster is “Workingman”. But they kept a low profile and remained small and fury like a hamster. William King, an Irish geologist, was the first to suggest the fossils looked human, but not entirely, and so should be another species.

All told, the early hominins analyzed to date fall roughly into three groups: (i) those with carbon isotope compositions indicating strong C 3 diets similar to those of savanna chimpanzees, (ii) those with variably mixed C 3 /C 4 diets, and (iii) those with carbon isotope compositions indicating diets of chiefly C 4 vegetation, as is typically seen for grass-eating ungulates in tropical climes.
