UNKNOWN is a four-part docuseries event that tells breathtaking stories of adventure and exploration in awe-inspiring uncharted territories. In South Africa’s Cradle of Humankind, Paleoanthropologist Lee Berger has found the world’s oldest graveyard; and it’s not human. If Lee and his team can prove that this ancient, small-brained, ape-like creature practiced complex burial ritual, it will change everything we know about hominid evolution and the origins of belief.
