At what point do you finally say, now wait a second, I can't see 30 genes getting exactly the right mutations which could be useful for increasing altitude adaptation surviving through natural selection choices, and out-competing all other genetic varieties in such a short time?
From the article:
quote:
The Beijing team analyzed the 3 percent of the human genome in which known genes lie in 50 Tibetans from two villages at an altitude of 14,000 feet and in 40 Han Chinese from Beijing, which is 160 feet above sea level. Many genes exist in a population in alternative versions. The biologists found about 30 genes in which a version rare among the Han had become common among the Tibetans. The most striking instance was a version of a gene possessed by 9 percent of Han but 87 percent of Tibetans.
My bold.
It appears that those alleles were already present in the population. If so, this is just selection occurring over ~150 generations.
This should not be a big deal for creationists. It's not as if the dog kind suddenly became the cat kind.
