​縄紋人全序首次被成功觧讀

呀，又测了一个，这个测序质量应该很高了，北海道气候更有利于古dna保存

之前测的那个IK002绳纹人是在爱知县发掘的

无论论坛人气多么衰落，一有日本的话题还是会一如既往地吵起来

Unique characteristics of the Ainu population in Northern Japan
Timothy A Jinam, Hideaki Kanzawa-Kiriyama[…]Naruya Saitou
Journal of Human Genetics volume 60, pages 565–571 (2015)

Various genetic data (classic markers, mitochondrial DNAs, Y chromosomes and genome-wide single-nucleotide polymorphisms (SNPs)) have confirmed the coexistence of three major human populations on the Japanese Archipelago: Ainu in Hokkaido, Ryukyuans in the Southern Islands and Mainland Japanese. We compared genome-wide SNP data of the Ainu, Ryukyuans and Mainland Japanese, and found the following results: (1) the Ainu are genetically different from Mainland Japanese living in Tohoku, the northern part of Honshu Island;

(2) using Ainu as descendants of the Jomon people and continental Asians (Han Chinese, Koreans) as descendants of Yayoi people, the proportion of Jomon genetic component in Mainland Japanese was ~18% and ~28% in Ryukyuans; (3) the time since admixture for Mainland Japanese ranged from 55 to 58 generations ago, and 43 to 44 generations ago for the Ryukyuans, depending on the number of Ainu individuals with varying rates of recent admixture with Mainland Japanese;

(4) estimated haplotypes of some Ainu individuals suggested relatively long-term admixture with Mainland Japanese; and (5) highly differentiated genomic regions between Ainu and Mainland Japanese included EDAR and COL7A1 gene regions, which were shown to influence macroscopic phenotypes. These results clearly demonstrate the unique status of the Ainu and Ryukyuan people within East Asia.


总之，我这里说的北指的是相对于东南亚-南汉-北汉-这一条过渡链而言，是一种独特的成分。即使某人不愿意承认，那也绝不是南，因为离南汉和东南亚远于北汉和朝鲜半岛。至于某人拿非洲来举例，那完全就是逻辑谬误，因为非洲离北汉南汉都非常远，不存在这样的过渡链

就这样的过渡链而言，绳纹比弥生更“北”，从琉球人与本州人的pca图上就可以看出来，因为这处于过渡链的末端。弥生本身也是东北亚大陆族群，肯定也比某人瞎说的江浙（南北之间的华东汉人）要偏北多了

大家不要吵🐶
