WORLD HISTORY

Detailed explanation-1: -Early humans (before Homo sapiens) The earliest humans developed out of australopithecine ancestors about 3 million years ago, most likely in Eastern Africa, most likely in the area of the Kenyan Rift Valley, where the oldest known stone tools were found.

Detailed explanation-2: -The first humans emerged in Africa around two million years ago, long before the modern humans known as Homo sapiens appeared on the same continent.

Detailed explanation-3: -Our species, Homo sapiens, has now spread to all parts of the world but it’s generally believed that we originated in Africa by about 200, 000 years ago. We interacted with local archaic human populations as we colonised the globe.

Detailed explanation-4: -It was from somewhere in the African continent, most scientists believe, that modern humans evolved around 200, 000 years ago before spreading across the world and becoming the dominant species we are today.

Detailed explanation-5: -Homo ergaster (or African Homo erectus) may have been the first human species to leave Africa. Fossil remains show this species had expanded its range into southern Eurasia by 1.75 million years ago.

Detailed explanation-6: -Africa is called the Cradle of Humankind because human life originated there. The name applies more specifically to a region in South Africa where fossil remains of several human ancestors have been found. The oldest evidence dates back three million years or more.
