According to a new study, the oldest known ancestors of humans already walked on two legs.

The conclusions are based on an analysis of fossilized bones discovered in Chad 20 years ago, which have now been analyzed.

According to the researchers, the remains belonged to a man they called Sahelanthropus tsatensisLived six to seven million years ago.

It would be the oldest known member of the hominin lineage, the evolutionary branch from the common ancestor of humans and chimpanzees to modern humans.
