'''Homo georgicus''' is a species of
hominin that was suggested in
2002 to describe fossil skulls and jaws found in
Dmanisi,
Georgia in
1999 and
2001, which seem intermediate between ''
Homo habilis'' and ''
H. erectus''. A partial skeleton was discovered in 2001. The fossils are about 1.8 million years old. The remains were first discovered in
1991 by Georgian scientist,
David Lordkipanidze, accompanied by an international team which unearthed the hominin remains. Implements and animal bones were found alongside the ancient
hominin remains.
At first, scientists thought they had found thirty or so
skulls belonging to ''
Homo ergaster'', but size differences led them to consider erecting a new species, ''Homo georgicus'', which would be the descendant of ''
Homo habilis'' and ancestor of Asian ''
Homo erectus''.
Interpretations
At around 600
cc brain volume, the skull D2700 is dated to 1.8 million years old and in good condition offering insights in comparison to the modern human cranial morphology. The cranium was the smallest and most primitive hominine skull ever discovered outside of Africa where typical hominines, Australopithecines and early genus Homo represent two distinctive evolutionary paths sharing a common ancestor. In Georgia the specimens with a brain half the size compared to modern ''
Homo sapiens'' were considered the smallest until the discovery of ''
Homo floresiensis'' from the island of Flores. There is a strong
sexual dimorphism present in the morphological beings revealing a primitive trait (less present in more modern humans in Europe (ie. ''
Homo antecessor'', ''
Homo heidelbergensis'' and ''
Homo neanderthalensis''), with males being significantly larger than females. Due to the dwarf morphology of this hominine, no subsequent role of ''H. georgicus'' can be so far determined. Theories remain debatable whether or not these hominines had a greater intelligence closer in equivalence to modern humans than previous hominines despite the small cranial capacity. ''H. georgicus'' may be the first hominin species to settle in
Europe, some 800,000 years before ''H. erectus''.
