Paleontologists have found traces of ancient tools in China, showing that the first representatives of our species have entered the territory of Asia, there are more than two million years ago.Their photographs and the results of scientists were presented in the journal Nature.

"Our discovery suggests that now we need to revise the time when the first representatives of our species left Africa and have started to settle on the ground, "said Robin Dennell (Robin Dennell) of the University of Exeter, United Kingdom.

The so-called human ancestors, the humans who are (Homo erectus) have appeared in eastern and southern Africa about two million years ago. In addition, they are considered the direct ancestors of the Neanderthals and the whimsical hobbit of the island of Flores. In addition, Homo erectus were the inventors of the world's first complex of work instruments, fire discoverers and first cooks, mastered the secrets of cooking food.

The upright people, as shown by the findings of Dmanisi in Georgia left Africa about 1.85 million years ago. They were the first representatives of our species to have managed to cross the limits of the "cradle of humanity", traditionally considered as the African continent. Dennell and his colleagues found that this probably happened earlier than planned, while digging in the Center. China, in a place called West Lake Hubin business center. Here, for three million years, have formed giant deposits of loess, compacted sand and clay, felled by the waters of the Yellow River.

Three years ago, paleontologists discovered a particularly thick layer of such deposits. progressively searched and studied. Inside we unexpectedly find not only the jaws of old cows and other animals, but also a hundred tools whose form and purpose were extremely varied.

For example, there were not only simple axes and scrapers, but also relatively complex tools – arrowheads, hammers, scissors and other highly specialized household items.

Despite their obvious age, paleontologists could not determine their age, such as the rate of loess formation, unlike many other sediments. rocks, could vary depending on the activity of the winds, the flow speed of the river and many other parameters.To solve this mystery helped the Earth's magnetic field, whose poles periodically change places. Traces of these revolutions, as scientists explain, are stored in the clay granules and in the particles of some rocks. This allowed us to determine which direction was turned to the compass at that time, when the old ones cut them and determined their approximate age.

Much of the tools were manufactured about 1.5 million years ago. the supposed exodus of humanity. At the same time, six scrapers and choppers, according to Dennell and his colleagues were much older – their age exceeded 2.12 million years.

This discovery, as the researchers note, suggests that the people of Dmanisi were not the oldest inhabitants of Asia – China, apparently, was inhabited much earlier than Georgia. How exactly did this happen is not clear, but the fact of this suggests that the first representatives of our species were more suited to the cold climate of Asia than one does. thought so.
