Abstract
Manipur, one of the northeastern states of India, lies on the ancient silk route and serves as a meeting point between Southeast Asia and South Asia. The origin and migration histories of Naga and Kuki tribal populations are not clearly understood. Moreover, Kukis have been traced to two different ancestries, which has created confusion among the people. The present study examined genomic affinities and differentiation of the Naga and Kuki tribal populations of Manipur, Northeast India. Twenty autosomal markers (8 Alu insertion-deletions, 12 restriction-fragment-length polymorphisms) were analyzed. Findings show genetic differences between Naga and Kuki tribal populations with respect to the allele distribution pattern, which was substantiated by genetic differentiation (GST = 5.2%) and molecular variance (AMOVA), where the highest percentage of among-group variances was observed between Naga and Kuki tribal groups (7.09%). However, genetic similarities with respect to allele distribution patterns in most of the loci were seen among their respective groups (Rongmei and Inpui, Thadou and Vaiphei). Rongmei and Inpui tribal populations (Naga group) belong to the Naga-Bodo linguistic group, and Thadou and Vaiphei (Kuki group) belong to the Northern Kuki-Chin linguistic group, suggesting that genetic similarities may not be independent of linguistic affinities. Despite differential genetic affinities, both Naga and Kuki tribal populations in Manipur show more proximity with Southeast Asian populations and Northeast Indian populations than with other Indian populations and global populations taken for comparison.
期刊介绍：
Human Biology publishes original scientific articles, brief communications, letters to the editor, and review articles on the general topic of biological anthropology. Our main focus is understanding human biological variation and human evolution through a broad range of approaches.
We encourage investigators to submit any study on human biological diversity presented from an evolutionary or adaptive perspective. Priority will be given to interdisciplinary studies that seek to better explain the interaction between cultural processes and biological processes in our evolution. Methodological papers are also encouraged. Any computational approach intended to summarize cultural variation is encouraged. Studies that are essentially descriptive or concern only a limited geographic area are acceptable only when they have a wider relevance to understanding human biological variation.
Manuscripts may cover any of the following disciplines, once the anthropological focus is apparent: human population genetics, evolutionary and genetic demography, quantitative genetics, evolutionary biology, ancient DNA studies, biological diversity interpreted in terms of adaptation (biometry, physical anthropology), and interdisciplinary research linking biological and cultural diversity (inferred from linguistic variability, ethnological diversity, archaeological evidence, etc.).
