Southeast Asia, located at the intersection of East Asia, South Asia and Near Oceania, is characterized by an extraordinary genetic and linguistic diversity: it has been occupied by multiple hominin species by at least 1.6 million years ago, with the first modern humans setting foot in the region around 50 thousand years ago, and has been the scene of a complex demographic history articulated in multiple migrations of diverse human populations. Their descendants are the result of multiple admixture events between these ancestral populations which often differed both genetically and linguistically, so that the current inhabitants of Southeast Asia speak a variety of languages, with the five major language families being represented by the Austroasiatic, Austronesian, Hmong-Mien, Kra-Dai and Sino-Tibetan languages. Here, 408 ancient genomes and 1573 modern genomes from 80 present-day populations originating from Southeast Asia and surrounding regions are analyzed using mainly the PANE software, with the aim of characterizing in a comprehensive genomic perspective the human genetic history of the broad area surrounding Southeast Asia from the Paleolithic to the present day.
Il Sud-est asiatico, situato all'incrocio tra Asia orientale, Asia meridionale e Oceania vicina, è caratterizzato da una straordinaria diversità genetica e linguistica: è stato occupato da molteplici specie di ominini da almeno 1,6 milioni di anni fa, con i primi esseri umani moderni che vi misero piede circa 50.000 anni fa, ed è stato teatro di una complessa storia demografica articolata in molteplici migrazioni di diverse popolazioni umane. I loro discendenti sono il risultato di molteplici eventi di mescolanza tra queste popolazioni ancestrali, spesso diverse sia geneticamente che linguisticamente, tanto che gli attuali abitanti del Sud-est asiatico parlano una varietà di lingue, con le cinque principali famiglie linguistiche rappresentate dalle lingue austroasiatiche, austronesiane, Hmong-Mien, Kra-Dai e sino-tibetane. In questo lavoro vengono analizzati 408 genomi antichi e 1573 genomi moderni provenienti da 80 popolazioni odierne provenienti dal Sud-est asiatico e dalle regioni circostanti, utilizzando principalmente il software PANE, con l'obiettivo di caratterizzare in una prospettiva genomica completa la storia genetica umana dell'ampia area circostante il Sud-est asiatico dal Paleolitico ai giorni nostri.

Abstract
Southeast Asia, located at the intersection of East Asia, South Asia and Near Oceania, is characterized by an extraordinary genetic and linguistic diversity: it has been occupied by multiple hominin species by at least 1.6 million years ago, with the first modern humans setting foot in the region around 50 thousand years ago, and has been the scene of a complex demographic history articulated in multiple migrations of diverse human populations. Their descendants are the result of multiple admixture events between these ancestral populations which often differed both genetically and linguistically, so that the current inhabitants of Southeast Asia speak a variety of languages, with the five major language families being represented by the Austroasiatic, Austronesian, Hmong-Mien, Kra-Dai and Sino-Tibetan languages. Here, 408 ancient genomes and 1573 modern genomes from 80 present-day populations originating from Southeast Asia and surrounding regions are analyzed using mainly the PANE software, with the aim of characterizing in a comprehensive genomic perspective the human genetic history of the broad area surrounding Southeast Asia from the Paleolithic to the present day.| File | Dimensione | Formato | |
