Anthropologists have found the advanced technology of the ancient people
Anthropologists at the Smithsonian National Museum of Natural History found that ancient people who lived in East Africa 320,000 years ago used colored pigments and complex instruments that were not characteristic of the Early Paleolithic. This is reported in a press release on Phys.org.
Artifacts were discovered during excavations in the Olorgesaili region in southern Kenya. The first evidence of human existence in this territory dates back to 1.2 million years ago. Archaic people (Homo heidelbergensis and Homo erectus) used a chopper-stone tool used as an ax, knife or pickaxe. However, the new finds were specialized and more finely crafted instruments, the age of which was 305-320 thousand years.
Some tools were made of obsidian, the sources of which were located at a distance of 24-88 kilometers from the site of excavations. This indicated that there was trade between different groups of people in Africa. Manganese crystals and ocher were also found, which were 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 among the ancient people, who, thus, increased their chances of survival.
