Researchers have found that most Nepali populations derive their maternal ancestry from lowland populations than highlanders.

Scientists from Hyderabad-based CSIR-Centre for Cellular and Molecular Biology (CCMB), Tribhuvan University of Nepal, DST-Birbal Sahni Institute of Palaeosciences in Lucknow, and Banaras Hindu University of Varanasi collaborated in what is termed as “the first largest study on the Nepalese populations to trace their origins.”

Investigators analysed mitochondrial DNA sequences of 999 individuals from different ethnic groups of Nepal—including Newar, Magar, Sherpa, Brahmin, Tharu, Tamang, and populations from Kathmandu and Eastern Nepal.

Dr K Thangaraj from CCMB who led the research told DH that some of the Nepalese were found to have ancestral links to Brahmins and Thakurs of Uttarakhand and Uttar Pradesh.

Located at a crossroads in the Himalayan region, Nepal offers a unique ground to understand south and east Asian genetic ancestry. The Himalayan mountains range of Nepal has served as a geographical barrier to population migration, while at the same time, its valleys have been avenues for trade and exchange.

Despite the long-term economic and cultural importance of the Himalayan trade routes, very little is known about the early population history of the region.

The results of the study have now helped the researchers fill several critical gaps in the history and past demographic events that shaped the present Nepalese genetic diversity.
