Why was Louis Leakey convinces that Africa was the cradle of humanity

Answer:Africa is known as the "Cradle of Humankind" because it is believed that all human life originated in Africa.

Explanation:In 1959, Mary and Louis Leakey were in the Olduvai Gorge in Eastern Africa when they uncovered more than 400 pieces of a fragmented skull. After doing some radiocarbon dating, the Leakey's were able to determine that the skull was 1.75 million years old. This would later become the first evidence that the human species had its roots in Africa.
