Homo erectus (ergaster) Dmanisi (D2700) and jaw (D2735) (1.75 to 2.0 million years).
The Dmanisi Homo erectus (ergaster) was discovered in 1999 by Abesalom Vekua, et al. in Dmanisi, Georgia. Our cast comprises the D2700 cranium and D2735 jaw. This small-brained specimen, found alongside Oldowan-like choppers and scrapers, undercuts the theory that hominids did not leave Africa until about one million years ago and only after becoming large-brained bipeds with well-developed tool-making abilities. The small capacity of the cranium D2700 (600cm3) is similar to that of the African H. habilis specimens. Despite their small cranial capacity, characteristics of the crania and mandibles show greater similarity to early African H. erectus/ergaster than to H. habilis. The skull is small and rounded at the back.
