The skull from Manot Cave dates to 55,000 years ago and may be the closest we've got to finding one of the earliest migrants from Africa.
Details appear in Nature journal.
"The skull is very gracile - there is nothing that makes it any different from a modern skull," Prof Israel Hershkovitz, from Tel Aviv University, told the Nature podcast.
"But it also has traits that are found in older specimens."
He added: "This is the first evidence that shows indeed there was a large wave of migrants out of East Africa, crossing the Sahara and the Nubian desert and inhabiting the eastern Mediterranean region 55,000 years ago. So it is really a key skull in understanding modern human evolution."

Manot Cave in Galilee was re-discovered during construction work in 2008
Physical features of the skull, such as a distinctive "bun-shaped" region at the back, resemble those found in the earliest modern humans from Europe.
This "implies that the Manot people were probably the forefathers of many of the early, Upper Palaeolithic populations of Europe", Prof Hershkovitz said.
Chris Stringer, research Leader in human origins at London's Natural History Museum, commented: "Manot might represent some of the elusive first -READ MORE LIN
