You've heard of Homo naledi, the strange "human ancestor" (really, a cousin) found a while back in South Africa. There were many skeletal remains in a cave, in the kind of shape you'd expect if they had crawled into the cave and died there, not much disturbed. They look enough like other members of our genus, Homo, to be called Homo, but if we assume that increase in brain size is the hallmark of our species, they seem to be an early grade.
