There is a basic consensus in the scientific community that there were other species close to humans, such as Neanderthals and Denisovans. It's generally understood that these species went extinct, with little bit of mixing but this video suggests we still have sub-sub-species, who evolved separately, which contradicts mainstream evolutionary biology beliefs. Btw thanks for suggestion I like these kind of documentary. I will definitely watch it.
