Cette d\u00e9couverte sugg\u00e8re de possibles rencontres entre humains modernes et n\u00e9andertaliens\/d\u00e9nisoviens en Asie du Sud, remettant en question les th\u00e9ories sur les interactions humaines pr\u00e9historiques. Elle r\u00e9v\u00e8le \u00e9galement une diversit\u00e9 exceptionnelle de g\u00e8nes n\u00e9andertaliens chez les Indiens, possiblement due \u00e0 l’isolement g\u00e9n\u00e9tique ou \u00e0 des traditions de mariage sp\u00e9cifiques.<\/p>\n\n\n\n

L’article souligne l’extraordinaire diversit\u00e9 de l’Inde, qui compte plus d’1 milliard et demi d’habitants et environ 5 000 groupes ethnolinguistiques et religieux. L’\u00e9tude, bas\u00e9e sur l’analyse du g\u00e9nome de 2 762 Indiens de diverses origines g\u00e9ographiques et ethniques, est d\u00e9crite comme la plus importante de son genre. Elle a permis de reconstituer 500 000 ans d’histoires de migrations et de m\u00e9langes de populations, confirmant que la plupart des Indiens sont un m\u00e9lange de trois populations ancestrales.<\/p>\n\n\n\n
