Homo naledi

Guest: Duane Jeffery, Ph.D., Professor Emeritus of Biology and Evolution at BYU  Homo naledi is the name given to a new species of human ancestor discovered deep in a cave not far from Johannesburg, South Africa. It’s among the most remarkable collections of hominid fossils ever uncovered. A team of slightly-built scientists shimmied through passages less-than-a-foot in diameter to collect 1,550 fossil fragments making up at least 15 individual skeletons.  And as with most amazing scientific discoveries, there are now more questions in need of answers. Where does Homo naledi fit in the human family tree?
