Research Shows Humans & Neanderthals Coexisted in Negev Desert

By: Andrew Isaacson

Prof. Elisabetta Boaretto of the Weizmann Institute and Dr. Omry Barzilai of the Israel Antiquities Authority discovered that humans and Neanderthals coexisted in the Negev Desert 50,000 years ago through research and excavation of the Boker Tachtit archaeological site in Ein Avdat National Park in central Israel.

The research published on Wednesday in the PNAS scientific journal provided the first evidence that both species lived together in the Middle East and discovered that Homo sapiens migrated from Africa to Israel’s Boker Tachtit.

Boker Tachtit is an important site for tracing early migration from human species out of Africa and documenting the transition from Neanderthals to modern humans.

Dr. Omry Barzilai, excavation director at the Boker Tachtit site on behalf of the Antiquities Authority, said Boker Tachtit is the first known site reached by modern man outside Africa, making this location and its dating essential.

“There is no doubt that, as they dwelt in and moved around the Negev, the two species were aware of each other’s existence,” he said. “Our research on the Boker Tachtit site places an important, well-defined reference point on the timeline of human evolution.”

The Max Planck-Weizmann Center for Integrative Archaeology and Anthropology funded the excavation.

For the research, dozens of carbon samples from the excavation were analyzed using radiocarbon dating in Prof. Boaretto’s laboratory at the Weizmann Institute of Science.

“For the first time in prehistoric research, the results of the dating prove the hypothesis that there was definitely a spatial overlap between the late Mousterian culture, identified with Neanderthal man, and the Emiran culture, which is associated with the emergence of modern man in the Middle East,” Dr. Barzilai said.

Neanderthals and Homo sapiens lived in the Old World together simultaneously during the Middle Palaeolithic period 250,000-50,000 years before present.

Israel and the Middle East have contained the remains of both Neanderthals and Homo sapiens and were the distribution limits of these species.

According to DNA studies, the widespread process of migration from Africa to Asia, Europe and the rest of the world led to the disappearance of Neanderthals and the assimilation into the modern human population.

The latest study confirms the hypothesis that there was some interaction and genetic exchange between ancient humans and cultures, and one of the intercultural encounters happened in the Negev 50,000 years ago.

Dr. Barzilai said future research will include discovering the nature of the encounter identified between both species and whether Neanderthals became naturally extinct, merged with modern man or disappeared in violent ways.
