Ancient people used stone ax 1.76 million years ago

A group of researchers has discovered that the earliest stone labor tool of ancient humans dates back to 1.76 million years, but was not carried away when the ancient people left Africa.

Upon arriving at an archaeological site along the northwest coast of Kenya's Lake Turkana, a team from the United States and France discovered double-edged knives and other large cutting tools that were previously excavated along with original stone pieces.

Using a sophisticated technique to date, researchers calculated the age of these tools by more than 1.76 million years. It is an older tool of labor that is similar to artifacts in Ethiopia and Tanzania, estimated at 1.4-1.6 million years ago.

This suggests that prehistoric people were involved in refining tools earlier than previously thought. Unlike simple stone tools made from stone stones, they were designed and designed by the ancient people.

These stone tools are believed to be of the ancestors of Homo erectus . It has an ax shape with an appropriate design for slaughtering animals, cutting wood and digging holes.

Homo erectus walks on two feet like modern humans, but has a flat skull, steep forehead and smaller brain, appearing about 2 million years ago in Africa.

The strange thing is that when migrating to Asia and Europe, most people do not discover tools with technology signs like these hand axes that were brought by the ancient people.

Enjoying this has a lot of theory.Some conjecture that the ancient people could not find materials in making new tools and lost tools along the way. Others said they would return to Africa later, where they developed hand axes.

Tryon researcher at New York University, had another idea, arguing that populations of territorial expanses out of Africa did not need an advanced technology because of little competition.

The first person who was "flexible behavior" and hand shaft "was something that they did when needed and abandoned when not needed , " Tryon said.

Geologists said they collected about 150 samples of sediment from the regions in 2007 to analyze their age.
