In 2015, scientists reported an astonishing discovery from deep inside a South African cave: more than 1,500 fossils of an ancient hominin species that had never been seen before.
The creatures, named Homo naledi, were short, with long arms, curved fingers and a brain about one-third the size of a modern human’s.
Now, after years of analyzing the surfaces and sediments of the elaborate underground cave, the same team of scientists is making another splashy announcement: Homo naledi — despite their tiny brains — buried their dead in graves.
They lit fires to illuminate their way down the cave, and they marked the graves with engravings on the walls.
It suggests that big brains are not essential for sophisticated kinds of thinking, he said, such as making symbols, cooperating on dangerous expeditions or even recognizing death.
