Scientists have always claimed that the first humans emerged in Africa 2 million years ago before the advent of modern humans. This means that pre-humans developed in Africa.
The origin of the human species was said to be east Africa. Humans underwent a series of genetic and cultural changes that resulted in the advent of modern humans.
Not all scientists agree that mankind had a single birthplace or origin. For example, an article in Arkeonews claims that Africa may not be where the first humans evolved.
It states that researchers have found evidence that the ancestral link between gorillas and humans occurred in the Eastern Mediterranean and not in Africa. According to them, the evidence shows that the first pre-humans entered the Balkan region of northern Greece.
Researchers found specimens of a fossilized hominid in Greece and Bulgaria. They had already believed that such hominids were extinct more than 3 million years ago so it was surprising to discover these remains. Using computer tomography, the researchers determined that the specimens were pre-humans. So pre-humans already existed in the Balkan region.
Thus, scientists claim that the split between humans and chimps occurred in the Mediterranean region.
Still, another scientific theory is that modern humans did not originate from a single population or a single location. Rather, human traits emerged from multiple populations that came into contact with each other and mixed.
Could it be that humans are just far more diverse than previously thought and that the term "humans" referred to several species and sub-populations?
