There are a lot of unsolved mysteries in our history, but over the years scientists have tried to solve them. The data gathered so far helped researchers figure out many things about the humanity’s past, but new information keep coming up as progress is made in this area.
Recently, we received some signals from the past. Scientific news from New York tells us that stone tools recovered from China are a proof that our ancestors left Africa earlier than we thought. The general idea so far was connected to the evidence of human-like creatures found outside the Black Continent years ago.
The oldest artifacts and skulls were found in the Georgian town of Dmanisi and are dated 1.8 million years ago. However, the evidence found now support the idea that humans left Africa thousands of years before it was initially calculated.
Michael Petraglia, an archaeologist at the Max Planck Institute for the Science of Human History in Jena, Germany declared that the new findings indicate the fact that the exit happened even before Homo sapiens appeared.
The archaeological site from China was hosting 96 artifacts including several chipped rocks, hammer stones and other tool fragments. The items were discovered in an area known as the Loess Plateau situated in the northern part of the Qinling mountains. A study recently published in the Nature journal mentions that, according to researchers’ discoveries, some of the objects are 2.1 million years old, according to the study in Wednesday’s journal Nature.
With all the excitement, an anthropologist from William Paterson University in New Jersey, Geoffrey Pope, said that the discovery might not bring significant changes. He recommended treating findings with extreme care and attention since they can be simple stones shaped by nature.
They wouldn’t want any confusion to interfere with their work, so scientists will continue with their research.
