So far, not working. The vast majority of Chinese still can't process lactose. Innate adaptation would work in one generation. Evolution takes generations to work.
And as they consume more milk- that protein will turn on, just like in my former lactose intolerant daughter who is now lactase persistent! She couldn't even eat pizza without getting sick. Now- she can drink glasses of whole milk without so much as a burp!
I have been in china- dairy products are almost non existent in the rural areas.
Also It can take years for someone who has had the protein turned off to have it turned on again. But if you continue a baby on lactose after weaning- it will stay lactose persistent! That is the simple fact.
It does not take generations to turn back on the lactase proteins. It does take time. And as China consumes more dairy- they will develop much higher % of lactose tolerant people in the same generation, if the people can get past the illnesses that go with lactose intolerance and continue on with consuming dairy.
Europeans, for example are generally immune to lactose intolerance. There has been a huge increase in the number of people of European descent in the world.
Because they continued to consume lactose! No need for the protein to turn off!
They just tend to evolve again, when the environment changes. That's been documented time, and time again. You were fooled by people who know no more than you do.
Some return to their "normal" state, most don't! The energy required to turn them immune ot their "disease" rendered them reproductively stunted!
Nope. See above. Notice that Chinese kids are not becoming more lactose-tolerant as they get older. Chinese are drinking more milk but it generally disagrees with them. The government is working hard to convince Chinese that it's a good thing. Seems weird, but there it is
