In 2013, a remote cave (as in "30 meters underground, through an 18-centimeter-wide passage" remote) revealed something surprising about what it means to be human. There, a pair of spelunkers stumbled on a chamber full of the fossilized bones of Homo naledi, a previously unknown hominid. From the position of the bodies—not to mention the whole "30 meters underground" thing—it was obvious that they had been placed there intentionally. We've always considered burial to be a relatively advanced behavior, but Homo naledi suggests that we share the ritual with even very primitive members of our family tree.
