老牛,你贴的这个文章不是支持我的观点么,你确信读懂了么。这是说这个基因起源于东亚,但是在Beringia成为dominant, 然后传到美洲。牛河梁 写了: 2023年 10月 7日 23:36 你这屁股决定祖先的伪科学家怎么知道人家没测过古白令利亚的古人类DNA样品,知道什么是广泛接受的事实和你的观点。

The new study reveals that the variant was so beneficial it spread to everyone in the Americas. When researchers led by biological anthropologist Leslea Hlusko of the University of California, Berkeley, examined data on the teeth of more than 5000 people from 54 archaeological sites in Europe, Asia, and North and South America, they found shoveled teeth—and hence, the gene variant that causes them—in about 40% of the individuals in Asia and all of the 3183 fossils of Native Americans they examined (who all lived before European colonization).
This suggests that some members of the first group to arrive in Beringia probably carried the gene, which arose in Asia. Then it quickly swept through the rest of the small isolated population of people who settled there between 28,000 and 18,000 years ago.
