Europe Or Africa

A recent study suggests the ancestors of humans may have come from Europe rather than Africa.

Scientists are still learning about humanity's ancient ancestors.

Based on anatomical and genetic evidence chimpanzees are humanity’s closest living relatives. Anthropologists want to find out where and when the split happened between the closest ancestors of humans, called hominins, and the ancestors of modern chimpanzees.

The Great Split

In the past, researchers theorized the split happened in Africa, about seven to ten million years ago. And that led to theories that human ancestors didn’t migrate to Asia and Europe until about two million years ago.

In 2017, a team of researchers from Europe and Canada published findings that human ancestors were in Europe around seven point two million years ago.

New Analysis

They were studying a fossil hominin discovered in Greece way back in 1944 by German soldiers digging a bunker. The hominin is called Graecopithecus freybergi.

The scientists analyzed the sediment in which the fossil was found, and the sediment in which a second specimen was found in Bulgaria. The ages for both came out the same, which is further evidence that the finding is reliable.

With that evidence, it may have potentially confirmed a theory: human ancestors were in Europe much earlier than when scientists had previously thought. The evolution of our earliest direct ancestors may have happened in Europe instead of Africa.

Teeth

But, anthropologists don’t agree Graecopithecus was actually a human ancestor. Because all they have are its jaw bone and teeth, the argument comes down to a matter of tooth structure.

Apes of many sorts were much more abundant back then than they are today. It’s estimated that there were one hundred different species. The tooth structure could have evolved independently in a non‑hominin.

So, while there’s evidence that supports Graecopithecus was in Europe, there needs to be further studies done on this species to determine whether or not it is an ancestor of humans.
