Han Chinese is the largest ethnic group in the world. During its development, it gradually integrated with many neighboring populations. To uncover the origin of the Han Chinese, ancient DNA analysis was performed on the remains of 46 humans (∼1700 to 1900 years ago) excavated from the Taojiazhai site in Qinghai province, northwest of China, where the Di‐Qiang populations had previously lived. In this study, eight mtDNA haplogroups (A, B, D, F, M*, M10, N9a, and Z) and one Y‐chromosome haplogroup (O3) were identified. All analyses show that the Taojiazhai population presents close genetic affinity to Tibeto‐Burman populations (descendants of Di‐Qiang populations) and Han Chinese, suggesting that the Di‐Qiang populations may have contributed to the Han Chinese genetic pool.
