The first tools can be very above what was believed until now, have been discovered in Kenya several stone objects dating from 3.3 million years ago, according to a study published today in the British journal “Nature”.
The sizes described in the work greatly anticipate the known origins of the genus “Homo”, which is distinguished by making tools, among other features, and includes modern humans, although it remains to determine which species hominids produced them.
The existence of stone tools associated with genus “Homo” had been dated at 2.6 million years old as a result of discoveries made in Ethiopia.
In this country stone tools found with the fossil remains of one of the oldest specimens of the genus “Homo”, the “Homo habilis”, belonging to the culture called olduvayense.
But the main author of the study published today in “Nature”, Sonia Harmand, West Turkana Archaeological Project shows that the unearthed at the site called Lomekwi 3 near Lake Turkana in Kenya, objects olduvayenses tools anticipate more than 700,000 years.
The collection includes anvils, stone hammers and singing the same material used for cutting and grinding.
The work shows that newly discovered pieces are older than the tools from the olduvayense culture and hominids Lomekwi area had a powerful hand grip and good control of motility, giving samples and cognitive abilities close relatives of humans.
The shape of the tools found in Kenya indicates that were used to crush all possible objects and sharp blades manufacturing strength, the report said.
The authors explain that the motor movements of the arm and hand these actions needed to be more like those made by chimpanzees and other primates to crack nuts and fruits that those who carried out the olduvayenses cultures when they use the tools.
