Oldest Human Skull Outside Of Africa Discovered In Israel

 An ancient human skull found in Israel could be one of the most important discoveries in understanding the history of human evolution. The 55,000-year-old skull found inside Manot Cave in northern Israel seven years ago was recently declared the oldest skull found outside of Africa. This rare fossil indicates that homo sapiens, our human race, originated in East Africa and migrated to the Middle East about 50,000-70,000 years ago.

The skull was accidentally discovered in the Western Galilee in 2008 when an unknown cave that had been sealed off for at least 30,000 years was exposed by a bulldozer operator. Inside of the cave, researchers from Israeli universities discovered a calcite-covered fragment of a small, anatomically modern human skull.

“This is a goldmine,” Tel Aviv University’s Prof. Israel Hershkovitz, who discovered the skull in Manot Cave, stated. “Most other caves are ‘disturbed caves,’ but this is untouched, frozen in time — truly an amazing find.” Hershkovitz lead the research team analyzing the skull, working jointly with the Israel Antiquities Authority and Ben Gurion University, but news of the discovery quickly spread. Anthropologists, archaeologists, geologists and other scientists from around the globe made their way to Israel to study the skull and the cave due to the important implications of the discovery.

There are competing theories on how modern humans came to populate the Earth. One of these, called the assimilation model, proposes that modern humans bred with archaic human populations, such as Neanderthals, to form hybrid groups who were absorbed into larger modern human populations. Strong genetic support for a version of this model came in 2010 from Leipzig-based evolutionary geneticist Svante Pääbo, who presented a draft sequence of a Neanderthal genome. His analysis showed that the ancestors of non-African people interbred with Neanderthals in the Middle East – before they migrated to Europe and Asia – sometime between 50,000 to 100,000 years ago. Another genetic analysis of 45,000-year-old DNA from a Siberian thighbone published last year further narrowed the likely interbreeding time to between 52,000 to 58,000 years ago. However, no one has been able to corroborate these findings with physical clues, until Hershkovitz concluded his study of the prehistoric skull in January.
