Tel Aviv: Human teeth
dating back 400,000 years, found in a cave near the Israeli town
of Rosh HaAyin, are the earliest evidence of modern man, and show
he lived twice as long ago as was previously thought, Tel Aviv
University said on its website Tuesday.
Until now, human remains from only 200,000 years ago had been
discovered in Africa, leading researchers to speculate that this
was the continent on which Homo sapiens originated.
The cave was uncovered in 2000 near Rosh HaAyin, east of Tel Aviv,
and a morphological analysis was performed on the teeth found
there.
The teeth are very similar to those of modern man, CT scans and
X-Rays showed. They are also "very similar" to evidence of modern
man from those discovered at two separate locations in northern
Israel and which date from 100,000 years ago, the university said.
According to the researchers working at the cave, their
discoveries are likely to change the perception, common until now,
that modern man originated in Africa.
While in recent years archaeological remains and human skeletons
found in China and Spain have undermined that thesis, the latest
findings are significant and invaluable, say Avi Gopher and Ran
Barkai of Tel Aviv University, who uncovered the cave.
