Human hands evolve earlier than we think

Scientists have discovered an ancient bone in a tomb in Kenya, revealing the ingenuity of human hands evolving much earlier than previous studies.

According to PNAS magazine, on top of that bone sample is well preserved, is a bone pattern linked to the index finger, a similar structure to the hand bones of modern people.

This is the oldest fossil evidence, proving that human hands evolved strong enough to be able to use tools. With this discovery, scientists gradually narrowed the gap in the history of human hand evolution.

After analyzing isotopes, neck bone samples were identified about 1.42 million years old, meaning earlier than the original studies of about 600 million years.

Professor Ward, an anatomy and pathologist at the University of Missouri, Columbia (USA), said: 'The isotopic process reflects the evolution of the level of ingenuity in human hands, possibly the grasping of Arrest has not been done correctly but strong enough to handle objects'.

The bone was found in the Kaitio area, west of Turkana, near the area where the first Acheulian tools were found, they were about 1.6 million years old.
