Ancient teeth raise new questions about the origins of modern man
Date:2/9/2011

BINGHAMTON, NY Eight small teeth found in a cave near Rosh Haain, central Israel, are raising big questions about the earliest existence of humans and where we may have originated, says Binghamton University anthropologist Rolf Quam. Part of a team of international researchers led by Dr. Israel Hershovitz of Tel Aviv University, Qaum and his colleagues have been examining the dental discovery and recently published their joint findings in the American Journal of Physical Anthropology.

Excavated at Qesem cave, a pre-historic site that was uncovered in 2000, the size and shape of the teeth are very similar to those of modern man, Homo sapiens, which have been found at other sites is Israel, such as Oafzeh and Skhul - but they're a lot older than any previously discovered remains.

"The Qesem teeth come from a time period between 200,000 - 400,000 years ago when human remains from the Middle East are very scarce," Quam said. "We have numerous remains of Neandertals and Homo sapiens from more recent times, that is around 60,00 - 150,000 years ago, but fossils from earlier time periods are rare. So these teeth are providing us with some new information about who the earlier occupants of this region were as well as their potential evolutionary relationships with the later fossils from this same region."

The teeth also present new evidence as to where modern man might have originated. Currently, anthropologists believe that modern humans and Neandertals shared a common ancestor who lived in Africa over 700,000 years ago. Some of the descendants of this common ancestor migrated to Europe and developed into Neandertals. Another group stayed in Africa and evolved into Homo sapiens, who later migrated out of the continent. If the remains from Qesem can be linked directly to the Homo sapiens species, it could mean that modern man either originated in what is now Israel or may have migrated from Africa far earlier that is presently acce
