Almost a year and a half since a trove of hominin remains, including a new member of the human family tree, was first discovered by two cavers exploring South Africa’s Rising Star cave system, Homo naledi’s age has been confirmed.
In papers published Tuesday in eLife, the team—led by National Geographic Explorer-in-Residence Lee Berger—provides an age range for the remains first reported in 2015: between 236,000 and 335,000 years old. The team also describes a second chamber within Rising Star that contains yet-undated H. naledi remains.
If these dates hold, it could mean that while our own species was evolving from other, large-brained ancestors, a tiny-brained primitive shadow lineage was lingering on from a much earlier period, perhaps two million years ago or more. The proposed age range for the fossils also overlaps with the early Middle Stone Age, fueling a provocative, though unproven, possibility: that the stone-tool record in South Africa from that time wasn’t just the handiwork of anatomically modern humans.
