Investigating Holocene India - Australia Connections using Ancient Genomics

许多关于人类迁徙的研究表明，在大约4.5万年前澳大利亚首次成为殖民地之后，这些人在很大程度上一直是孤立的，直到欧洲人的到来。相比之下，最近的研究表明，从印度到澳大利亚的移民浪潮大约发生在4230年前。然而，这些近期研究的一个主要缺点是，所使用的序列数据来自可能与欧洲人杂交的现代澳大利亚土著。为了解决这个问题，我们将对古印度人和澳大利亚土著人的亚化石骨骼的完整基因组进行测序，并直接调查这种可能的印度-澳大利亚联系。

A number of studies of human migration suggest that after initial colonisation of Australia around 45,000 years ago, these people remained largely isolated until the arrival of Europeans. In contrast recent studies have suggested that a wave of migration from India into Australia occurred approximately 4,230 years ago. However, a major drawback of these recent studies is that sequence data used was from modern indigenous Australians who were potentially admixed with Europeans. To address this issue we will sequence complete genomes from sub-fossil bones of ancient Indian and Indigenous Australian people and directly investigate this possible India-Australia connection.
