Enigma Man: A Stone Age Mystery (2017) [720p] - A team of Australian and Chinese scientists discover mysterious ancient human remains from a remote cave in South West China. The bones are unlike any living human or any ancient human known to science, yet they were alive at the same time as humans.
Kind of falls in with my own theory that many groups developed in isolated places and re-encountered other human branches, and likely interbred after having evolved separately for tens of thousands of years. The reconstructions reminded me of some (uncommon) facial features found in part of modern India.
