The recent finding of a new hominid is compelling, but a lot of this documentary is only about a handful of discoveries. Still fascinating, though, Unknown: Cave of Bones provides an intimate look at the team going back into the Rising Star cave system in 2022 to further explore and uncover more about Homo naledi. Over 100,000 years before the human, the Homo naledi were burying their dead, using tools, and drawing on cave walls. The team is able to piece together almost full skeletons of the species, as well as make interesting claims about tool usage, brain size, diet, burial rituals, cave art, and possible spiritual beliefs.

But the length of this film is a bit long to be singularly focusing on only a few things (burial, a tool, some cave wall scratches), even if those things are greatly impactful, as everyone often points out. What do these discoveries suggest about the actual origins of the human? Maybe the human was never that special after all? Was brain size actually an indicator of ability and intelligence? Also, much is made of how difficult this particular cave section (where the Homo naledi was originally discovered) is to explore, and much drama is made of one particular person's ability to reach the deepest part.
