To discover is the question of which hominids manufactured these tools.
A team of researchers led by Mohamed Sahnouni, of the National Research Center on Human Evolution in Burgos (Spain), has refuted the idea that the cradle of humanity is in East Africa. And all thanks to a surprising find made in the region of Ain Hanech, Algeria, in the north of the African continent.
There archeologists found stone tools and animal bones with cut marks that appear to be contemporary to the oldest stone tools discovered in East Africa, dating back 2.6 million years ago, reportsScience Daily .
According to the study, the pieces found in Algeria - with an estimated age of2.4 million yearsfor tools and1.9 millionyears for animal bones - were found on two levels of the place known as Ain Boucherit. It is specified that the tools were made with limestone and flint available in the area and are typical for the Olduvayense stone technology.
"The lithic industry of Ain Boucherit, which is technologically similar to that of Gona and Olduvai, shows that our ancestors ventured into every corner of Africa, not only in East Africa," said Mohamed Sahnouni. According to the scientist, "the evidence from Algeria changes the previous opinion that eastern East Africa was the cradle of humanity,in fact, the whole of Africa was the cradle of humanity, " he said.
To discover remains the question of which hominids made these tools in Algeria, because no human remains were found contemporary to the pieces.
