Scientists have found more evidence possible human ancestors – Homo naledi – in a South African cave.
“The discovery in South Africa of an inaccessible subterranean chamber filled with the broken bones of ancient human relatives — nobody yet knows quite how ancient — is exciting news indeed, and not only for specialists in paleoanthropology.”
The New York Times:
“Acting on a tip from spelunkers two years ago, scientists in South Africa discovered what the cavers had only dimly glimpsed through a crack in a limestone wall deep in the Rising Star cave: lots and lots of old bones.
“The remains covered the earthen floor beyond the narrow opening. This was, the scientists concluded, a large, dark chamber for the dead of a previously unidentified species of the early human lineage — Homo naledi.”
Cenk Uygur of The Young Turks helps to put the discovery into a (humorous) political context in the video.
