进化过程古遗传学过去十年的发展表明,现代人在全新物种——智人的出现过程中并没有一个系统发育学意义上的起源,因此,解剖学,行为学和遗传学方面的现代性并不是一个相同且单一事件的结果.本文研究了东亚解剖学,行为学和遗传学方面的证据,现代性在每个方面都可以被理解为多地区进化过程的一个片段,而不是一个整体....
Genetic studies using autosomal, mitochondrial DNA and Y-chromosome markers all point to an African ancestor of East Asians. A close examination of human fossils in China reveals a gap that spans from 100,000 to 50,000 years ago. A survey of more than 1,000 East Asian Y chromosomes shows...
Origin of modern humans in East Asia:clues from the Y chromosome chromosome data of East Asians provides clues to elucidate modern human origins and evolution in the neighboring regions,i.e.America,Oceania and the Pacific... H Shi,SU Bing - 生物学前沿:英文版 被引量: 0发表: 2009年 mtDNA ...
East Asian populations with a specific focus on the relative similarities of Koreans, Japanese, and Chinese. Korea represents an important region for understand- ing population structure and origin of East Asians be- cause of its location in Northeast Asia between China ...
The genetic data of the Y chromosome reflects a clear prehistoric evolution and migration course of East Asians. As well, the Y chromosome data of East Asians provides clues to elucidate modern human origins and evolution in the neighboring regions, i.e. America, Oceania and the Pacific Islands...
East Asia, geographically extending to the Pamir Plateau in the west, to the Himalayan Mountains in the southwest, to Lake Baikal in the north and to the S
(Fig.4, Supplementary Fig.S8). In the PCA, principal component one separates East and West Eurasians, and principal component two separates Southern and Northern East Asians. A cline was formed between the Northern Siberian Nganasan population in the top-right of the PCA plot and the ...
Are San people related to Asians? Is Nguni Bantu a tribe? Is Bantu an ethnic group? Are the Sentinelese people of African heritage? When were the San people in Africa around? Where do the San Bushmen live? Where did Native Americans originally come from?
There has been little previous research on self-harm among people of Chinese origin living in the UK, although this population has grown substantially in recent years and China is now the largest source of international students at UK universities. We co
In the negative values of PC3, South Asians (#15) stand as intermediate between Africans-Oceanians and Eurasians, Europeans (#13 and 14) cluster with South-East Asians (#16) and East-Asians (#17 and 18), and Inuits (#19 and 20) are relatively close to North Americans (#21). The ...
