What Is Homo Naledi, The Ancient Human Species Unexpectedly Found In The Back Of A South African Cave?

Scientists have discovered 15 partial skeletons of a new, human-like species, in the biggest discovery of its kind in South Africa. The researchers found the skeletons in a burial chamber deep in a cave system. In late 2013, an amateur caver showed up to Lee Berger's house with a fossil jawbone in hand. After looking it over, Berger and the caver broke out a few beers and called National Geographic, according to CNN.

Berger, an American paleoanthropologist and professor at the University of the Witwatersrand in Johannesburg, South Africa, told CNN that when the first remains of the new human-like species, called the Homo naledi, were found in Rising Star Cave, his team had no idea that it would change ideas about our human ancestors. The species not only appears to be a human relative, but it also appears to have buried its dead, which is a behavior that scientists previously thought was limited only to humans, according to CNN.

Berger told BBC News that he believed the naledi could be among the first of our genus, Homo, and that they could have lived in Africa up to three million years ago, but expressed that he wants to avoid calling this discovery the "missing link" in our mysterious heritage. Rather, he said he prefers to call the naledi a "bridge" between more primitive bipedal primates and humans:


The name of the species, naledi, means "star" in the local Sesotho language and refers to the cave where the bones were discovered, according to The New York Times. Altogether, Berger said his team found more than 1,550 fossil elements, with every bone in the body represented multiple times, making the naledi the "best-known fossil member of our lineage," according to the The New York Times.

Professor Chris Stringer of the Natural History Museum emphasized just how important Berger's discovery is, according to BBC News:

Berger told BBC News that the number and variety of bones that they found will help them "know everything about this species":
