马达加斯加的遗传多样性是一千多年前印度洋上发生的一个特殊的全球化进程的结果。以前的努力，以确定亚洲起源的马达加斯加强调婆罗洲广泛作为一个潜在的来源，但到目前为止，没有确定的来源人口。在这里，我们已经产生了两个东南婆罗洲人口，班贾尔和Ngaju的全基因组数据，以及整个印度洋地区的人口公布的数据。我们在班贾尔人中找到了有力的证据，证明马达加斯加人的亚洲血统。这个群体出现在马来帝国在婆罗洲东南部的长期贸易站，这有利于马来人和婆罗洲本土群体Ma'anyan之间的混合。通过对遗传学、历史学和语言学数据的分析，我们发现，在马来人领导的航行中，班贾尔人是马达加斯加基因库建立过程中分析群体中最有可能的亚洲来源。
Malagasy genetic diversity results from an exceptional protoglobalization process that took place over a thousand years ago across the Indian Ocean. Previous efforts to locate the Asian origin of Malagasy highlighted Borneo broadly as a potential source, but so far no firm source populations were identified. Here, we have generated genome-wide data from two Southeast Borneo populations, the Banjar and the Ngaju, together with published data from populations across the Indian Ocean region. We find strong support for an origin of the Asian ancestry of Malagasy among the Banjar. This group emerged from the long-standing presence of a Malay Empire trading post in Southeast Borneo, which favored admixture between the Malay and an autochthonous Borneo group, the Ma’anyan. Reconciling genetic, historical, and linguistic data, we show that the Banjar, in Malay-led voyages, were the most probable Asian source among the analyzed groups in the founding of the Malagasy gene pool.
