Our earliest human ancestors left Africa and colonized East Asia more than two million years ago, earlier than we thought it would be. , says a study on tools and ancient bones
. Sharp pieces were found in a locality called Shangchen in the south of the Chinese Loess Plateau.
The older ones are about 2.12 million years old and are about. 270,000 years older than the 1.85 million-year-old skeletons and stone tools from Dmanisi, Georgia, which were previously the first evidence of humanity outside of Africa
This shows that the first humans occupied the Chinese Loess Plateau under different climatic conditions. 2.12 million years ago, the researchers said.
"Our discovery means that it is now necessary to reconsider the moment when the first humans left Africa," said Robin Dennell, professor at Exeter University, UK. Stone artefacts, described in the journal Nature, were found mainly in 11 different layers of fossil soils that developed in a hot, humid climate.
16 other items were found in six layers of loess that developed in cooler, drier conditions. These 17 different layers of loess and fossils have formed over a period of nearly a million years.
All show signs of use – the stone had been intentionally crumbled. Most were made of quartzite and quartz probably from the foothills of the Qinling Mountains, 5-10 km south of the site, and the streams flow from it.
Animal bone fragments aged 2.12 million years were also found. the researchers said.
