Language and Genes Attest Different Histories in Island Southeast Asia
نویسندگان
چکیده
Recent work on autosomal DNA genetic variation across Southeast Asia suggests that genetic diversity largely reflects Pleistocene colonization by modern humans, and was not influenced to any significant degree by major cultural and linguistic changes during the mid-to-late Holocene (roughly, from ~5,000 years ago to the present). These results seemingly show that the spread of Austronesian languages across Island Southeast Asia was not associated with population movements that were significant enough to affect the overall phylogeny of the autosomal DNA tree. Consequently, the spread of genes is not significantly linked to the spread of languages in Island Southeast Asia; each represents different processes of different antiquity.

متن کاملFrom Domestication Histories to Regional Prehistory: Using Plants to Re-evaluate Early and Mid-Holocene Interaction between New Guinea and Southeast Asia
Emerging records of plant distributions and domestications for three carbohydrate-rich plants indicate highly complex histories of social interaction between New Guinea and Island Southeast Asia during the early and mid-Holocene. Phytogeographic, morphological, molecular and archaeobotanical evidence suggests variable histories of domestication: for Musa bananas is complex and involved inter-re...
متن کاملThe frequency of explosive volcanic eruptions in Southeast Asia
There are ~750 active and potentially active volcanoes in Southeast Asia. Ash from eruptions of volcanic explosivity index 3 (VEI 3) and smaller pose mostly local hazards while eruptions of VEI ≥ 4 could disrupt trade, travel, and daily life in large parts of the region. We classify Southeast Asian volcanoes into five groups, using their morphology and, where known, their eruptive history and d...
متن کاملReconstructing Demography and Social Behavior During the Neolithic Expansion from Genomic Diversity Across Island Southeast Asia
Archaeology, linguistics, and increasingly genetics are clarifying how populations moved from mainland Asia, through Island Southeast Asia, and out into the Pacific during the farming revolution. Yet key features of this process remain poorly understood, particularly how social behaviors intersected with demographic drivers to create the patterns of genomic diversity observed across Island Sout...
متن کاملThe Pacific lineage (2E) of JC polyomavirus is prevalent in Sumba Island, Eastern Indonesia
Recent studies have identified a Pacific lineage (2E) of JC polyomavirus (also designated as JC virus or JCV) that occurs in both Island Southeast Asia and Oceania, but not in mainland Asia. It has been postulated that this lineage traveled with Austronesian-speaking people who are now spread throughout Island Southeast Asia and Oceania (excluding Australia and inland and southern New Guinea). ...
