00:00Early humans may have left Africa far earlier than scientists thought.
00:04A site in the Jordan Valley called Ubadia is at least 1.9 million years old.
00:09Earlier estimates put it between 1.2 and 1.6 million years old.
00:14That makes it one of the oldest known places humans lived outside Africa.
00:18It's now about the same age as Dmanisi, a key early site in the country of Georgia.
00:24Ubadia is famous for hand axes, large stone tools shaped on both sides.
00:29To date it, researchers used three independent methods.
00:32One measured rare isotopes created by cosmic rays in buried rocks.
00:36Another read Earth's ancient magnetic field recorded in lake sediments.
00:40A third dated fossil freshwater snail shells.
00:43The findings suggest different groups carried different tool-making styles out of Africa around the same time.
00:49Humanity's first journey out of Africa may have been busier than we knew.
