The occupants of Dmanisi "are the first representatives of our own genus outside Africa, and they represent the most primitive population of the species Homo erectus
known to date," added Lordkipanidze.
At first, Brown and his colleagues thought a process known as island dwarfism, which favors smaller hominids better able to cope with the poor food supply in the rain forest, caused a population of Homo erectus
to evolve into the tiny H.
The first Homo erectus
in Asia was discovered in Indonesia in around 1888 when Eugene Dubois discovered femurs, teeth and other skeletal remains dating back 400,000 to 800,000 years.
Statistically this is not very likely, she says, but nevertheless there were researchers who proposed up to five contemporary species of early Homo in Africa, including Homo habilis, Homo rudolfensis, Homo ergaster and Homo erectus
8m years ago probably represent one species best described as Homo erectus
, which then expanded through Eurasia and as far as China and Java.

They appear to possess features of both the primitive ape-like Australop-ithecines and the far more human-like Homo erectus
- thought to be the direct ancestor of our own species, Homo sapiens.
Homo sapiens, the species to which every human on Earth today belongs, is assumed to have arisen from Homo erectus
in eastern Africa more than a million years ago.
They belonged to a human ancestor known as Homo erectus
Scientists say they descended from Homo erectus
, a species that died out about 250,000 years ago, just before the emergence of modern humans.
According to anthropological studies, Homo erectus
made little progress over millions of years until just recently and many branches of that species, including the incredibly tough Neanderthals, went by the wayside and were not the jack-of-all trades who ultimately survived and created the first cave paintings.
