New Species of Human found! #HomoNaledi #Evolution

Amazing discovery by scientists in a south african cave: a new species of human, perhaps one of our most primitive ancestors! Scientists are still unsure about the age of the fossils, but they are predicting somewhere between 2.5 million and 2.8 million years old! The bones had been discovered nearly two years ago, but the work is out this week in the open access (yay) journal eLife.

The New York Times has a nice summary:

The new hominin species was announced on Thursday by an international team of more than 60 scientists led by Lee R. Berger, an American paleoanthropologist who is a professor of human evolution studies at the University of the Witwatersrand in Johannesburg. The species name, H. naledi, refers to the cave where the bones lay undisturbed for so long; “naledi” means “star” in the local Sesotho language.

In two papers published this week in the open-access journal eLife, the researchers said that the more than 1,550 fossil elements documenting the discovery constituted the largest sample for any hominin species in a single African site, and one of the largest anywhere in the world. Further, the scientists said, that sample is probably a small fraction of the fossils yet to be recovered from the chamber. So far the team has recovered parts of at least 15 individuals.

“With almost every bone in the body represented multiple times, Homo naledi is already practically the best-known fossil member of our lineage,” Dr. Berger said.
