This is about the dumbest video I have ever come across. The narrator is discussing government classifications of race not scientific classes of race but narrates as though there is only the possibility of government classifications.
Further, there is an underlying implied misunderstanding of the nature of scientific classification. There may be an "ideal" model for a classification but great deviations from that ideal. If we classify birds as a species that flies, is a "bird" with a broken wing still a bird? Is a car without wheels still a car?
