A genetic study published in 2020 in the Journal ScienceDirect by Rowold et al. found that the great majority of Indian people ("caste people"), which make up about 91,4%, are closely related to West-Eurasians (Europeans and Middle Easterners). Northern Africans (samplified by Egyptians) were part of this cluster but shifted towards Sub-Saharan Africans. East Asians and Southeast Asians were most distant to both West-Eurasians and Sub-Saharan Africans and formed a completely separate cluster with each other. Interesingly, non-caste populations of India (samplified by the Soliga people, one of the Adivasi) which make up about 8,6% of Indians population, were found to be shifted towards Sub-Saharan Africans and share specific alleles. A link to certain Oceanians was also detected, suggesting ancient gene-flow.
