Anthropologists of the National Museum of natural history, Smithsonian institution found that the ancient people living in East Africa, 320 thousand years ago, used coloured pigments and complex instruments that are not characteristic of the early Paleolithic. About it reported in a press release on Phys.org.
The artifacts were discovered during excavations in the region Olorgesaile in the southern part of Kenya. The first evidence of human existence on this territory are dated to 1.2 million years ago. Archaic humans (Homo heidelbergensis and Homo erectus) used ax a stone tool used as an axe, knife or pickaxe. However, the new findings represented a more specialized and finely-made tools, whose age was 305-320 thousands of years.
Some tools were made of obsidian, sources of which were 24-88 kilometers from the site. This pointed to the fact that between different groups of people in Africa, trade was conducted. Was also discovered crystals of manganese and ochre, which was used as a coloring material.
The researchers also found that the age of the artifacts corresponded to the period of climatic instability in the region. Changes in the environment, according to scientists, contributed to the technological and social breakthrough of the ancient people, who thus increased their chances of survival.
