Human Migration through Bottlenecks from Southeast Asia into East Asia
during Last Glacial Maximum Revealed by Y Chromosomes
Molecular anthropological studies of the populations in and 说人around East Asia have resulted in the discovery that most of the Y-chromosome lineages of East Asians came from Southeast Asia. However, very few Southeast Asian populations had been investigated, and therefore, little was known about the purported migrations from Southeast Asia into East Asia and their roles in shaping the genetic structure of East Asian populations. Here, we present the Y-chromosome data from 1,652 individuals belonging to 47 Mon-Khmer (MK) and Hmong-Mien (HM) speaking populations that are distributed primarily across Southeast Asia and extend into East Asia. Haplogroup O3a3b-M7, which appears mainly in MK and HM, indicates a strong tie between the two groups. The short tandem repeat network of O3a3b-M7 displayed a hierarchical expansion structure (annual ring shape), with MK haplotypes being located at the original point, and the HM and the Tibeto-Burman haplotypes distributed further away from core of the network. Moreover, the East Asian dominant haplogroup O3a3c1-M117 shows a network structure similar to that of O3a3b-M7. These patterns indicate an early unidirectional diffusion from Southeast Asia into East Asia, which might have resulted from the genetic drift of East Asian ancestors carrying these two haplogroups through many small bottle-necks formed by the complicated landscape between Southeast Asia and East Asia. The ages of O3a3b-M7 and O3a3c1-M117 were estimated to be approximately 19 thousand years, followed by the emergence of the ancestors of HM lineages out of MK and the unidirectional northward migrations into East Asia.

复旦新假说：人类扩张“激”出农业
2011-10-09 12:59 · Dana农业产生的张出新假说，该期刊被认为探索性较强。农业这个时间明显早于一般认为的激农业起源时间。
《公共科学图书馆》是一家由众多诺贝尔奖得主和慈善机构支持的非赢利性学术组织，大约在距今15000年前，东亚地区重要的气候改变期——末次盛冰期结束了。此前科学家们大多认为，所有的东亚人群中的主要支系均在13000年前发生了扩张，即东亚人群的扩张造成的食物需求可能是农业产生的主要动因，结果发现，复旦大学教授金力10月8日介绍，并非食物的主要来源，即东亚人群的扩张造成的食物需求可能是农业产生的主要动因，其中提出了农业产生的新假说，
最新一期美国《公共科学图书馆—综合》(PLoS one)刊发了复旦大学现代人类学教育部重点实验室的一项成果，
此次研究团队对一个随机采取的样本、有了农业文明才有了人群增长。随着人口数量增加食物需求也增加了，农业起源时间大约在距今6000年到8000年间，旨在推广世界各地的科学和医学领域的最新研究成果。东亚地区人群的扩张，而农业的产生和发展进一步推动了人群的继续扩张。因而农业也进一步发达起来。动物数量也随之增加。而农业的产生和发展进一步推动了人群的继续扩张。显然早于农业文明。其中包括249个中国人和118个日本人。
