An ancient human vertebra at the ‘Ubeidiya archeological site in the Jordan Valley, just south of the Sea of Galilee, provides evidence that human migration out of Africa came in waves and was not a one-off event as previously believed.
The first wave of human migration from Africa to Eurasia reached the Dmanisi site in the Republic of Georgia in the Caucasus Mountains about 1.8 million years ago. The hominin fossils at Dmanisi have been identified as Homo erectus. In the journal Scientific Reports, researchers report that another wave has now been documented at the ‘Ubeidiya site, registered as occurring about 1.5 million years ago.
