No, the nationalism is a real issue, though it's not a majority view among Chinese researchers. What Wu claims above is directly and unambiguously contradicted by genetic evidence. Han are overwhelmingly O-M122 (sometimes written as O2 or O3) which absolutely goes back to the common African ancestor. You can look up the lineage yourself on the wikipage for haplogroups. What's true is they're a fairly recent split off the "spine" This is a settled matter, not one where HN is somehow censoring evidence based debate. The argument is fundamentally dishonest vs the evidence in total. Edit: Just to follow up with more useful information: What we are learning that's overturning some conventional views from recent digs in India and across Asia is about how technology/culture diffused amongst modern humans once they were resigning there. We're finding it was more of a web than a linear diffusion as previously thought. But that's all, again, among modern humans, not evidence of independent evolution of the Han people from homo erectus.
