Sujet:
Genetic Structure of Island Southeast Asia:Identifying Sources and Dates for Recent Admixture EventsUsing High-resolution Data from the Philippines and Timor Leste
Date:
Mardi 3 juin à 15h00
Lieu:
Salle 703, Bâtiment de recherche, IHP, Academia Sinica
Résumé:
The first humans in Insular Southeast Asia (ISEA) arrived at least 50,000 thousand years ago and the subsequent history of the region includes further major waves of migration that have left genetic imprints across the region. The last of these is associated with the spread of the Malayo-Polynesian (MP) branch of the Austronesian language family, which commenced at least 3,000 years ago but the resulting genetic footprint is unresolved.Attempts to correlate the distribution of MP languages with measures of DNA diversity have suffered from incompatible chronologies, with genetics typically displaying signals from the Pleistocene. Where appropriate methods have been employed the results consistently point to the Philippines as a potential source for admixture events within the last 3,000 years but rely on very few data points. Here, I describe a state-of-the-art investigation of ISEA genetic diversity that includes high-resolution data from 123 ethnolinguistic groups of the Philippines and Timor Leste, an ongoing region of contact between Austronesian and Papuan languages. The results uncover hitherto unsuspected genetic structure within the Philippines, identify specific components found across eastern Indonesia and Sulawesi, to the exclusion of potential sources in Luzon.
La conférence sera organisé par l'Institut d'histoire et de philologie, Academia Sinica, et le Centre EFEO de Taipei.
La conférence sera donnée en anglais. Entrée libre.
