first tools can be very above what was believed until now, have been discovered in Kenya various stone objects dating back 3.3 million years, according to a study published in the British scientific journal “Nature”.
The sizes described in the work greatly anticipate the known origins of the genus “Homo”, which is distinguished by making tools, among others features, and includes modern humans, although it remains to determine which species of hominid produced them.
The existence of stone tools associated with gender “ Homo ” was dated at 2.6 million years ago in the wake 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 lead author of the study published today in “Nature”, Sonia Harmand, West Turkana Archaeological Project shows that the objects unearthed in the site called Lomekwi 3 near Lake Turkana in Kenya anticipate tools olduvayenses 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, showing cognitive abilities and close relatives of humans.
The shape of the tools found in Kenya indicates that were used with all possible force to crush objects and make sharp blades, the report says.
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 olduvayenses cultures when using tools
