Okay, I got more information from my students. I was not there, but all of my students were and their English is good enough that I don’t think I’m really losing a lot in translation.
It was a cross-provincial forum with “experts” from several provinces. Only Taiwan and Hong Kong represented the “Chinese people are the same species as the rest of humanity” side. The rest of the provincial representatives (including people from our school’s department) sided with the scientists from Beijing University.
The fact that the Beijing University scientists bothered to come to our low-ranked school really impressed the students. It’s as if the top scientists at Yale gave a talk at your local community college.
Meanwhile, the Hong Kong representative leading the “common ancestor” duo could not speak Mandarin and while they could apparently fly people from every corner of China in, they did not bother to get an interpreter. He presented most of his evidence in English, which most of the students could not understand particularly well. Needless to say, they were underwhelmed by his evidence.
My students interpreted this as the “Chinese theory” versus the “Western theory.” I’m not sure if that is how it was meant to be interpreted, but that is what they got out of it.
Their meaning definitely was that we are completely different species. They said it’s like Neanderthals, except instead of dying out homo erectus evolved into Asian people. They argued that there would be no way for the "other’ branch of humanity to cross geological barriers involved.
One metaphor they used was lions and tigers. They said that lions and tigers are different species, but they can produce offspring.
Likewise, Chinese and foreigners can produce offspring- but the scientists argued that these offspring would have “subtle genetic abnormalities” that would make them weaker and prone to diseases that only show up late in life. They likened it to genetically engineered food, and said that it went against nature.
The students walked away almost entirely convinced. It was a slam dunk for the Beijing scientists.
Frankly, I’m a bit terrified right now. I’m no optimist, and I had no idea things were that bad. I mean, this was a government sponsored all-expenses paid big-deal conference at my small school. What the hell is even going on?
