Two genetic studies (Shinde et al. 2019 and Narasimhan et al. 2019,) analysing remains from the Indus Valley civilisation (of parts of Bronze Age Northwest India and East Pakistan), found them to have a mixture of ancestry: Shinde et al. found their samples to have about 50-98% of their genome from peoples related to early Iranian farmers, and from 2-50% of their genome from native South Asian hunter-gatherers, with the Iranian-related ancestry being on average predominant. The samples analyzed by Narasimhan et al. had 45–82% Iranian farmer-related ancestry and 11–50% AASI. The analysed samples of both studies have little to none of the "Steppe ancestry" component associated with later Indo-European migrations into India. The authors found that the respective amounts of those ancestries varied significantly between individuals, and concluded that more samples are needed to get the full picture of Indian population history.
