Ancient DNA uncovers extinct bovine species linked to modern yaks
Scientists analyzing ancient DNA have identified a previously unknown extinct bovine species that shares a genetic relationship with present-day yaks. The discovery sheds new light on the evolutionary history of high-altitude cattle species in Asia.

Researchers examining genetic material from fossilized remains have identified a previously undocumented extinct bovine that is closely related to contemporary yak populations. The findings, derived from ancient DNA analysis, reveal new branches in the evolutionary tree of Asian cattle species and provide insights into the domestication and migration patterns of these animals across the region.
The extinct species shares distinctive genetic markers with modern yaks, suggesting a common ancestor and indicating that the lineage diverged during a critical period in the evolutionary history of high-altitude ungulates. DNA evidence indicates the animal existed during a timeframe that bridges early wild populations and the domesticated yak varieties known today.
Experts say the discovery underscores how ancient genetic material can reveal species that left minimal archaeological traces. By studying preserved DNA fragments, scientists can reconstruct relationships between extinct and extant populations, painting a more complete picture of how Asian bovine species adapted to mountainous environments.
The research contributes to ongoing efforts to understand yak domestication and the genetic diversity of Himalayan and Central Asian livestock. Further analysis of ancient DNA from across the region may uncover additional extinct species and clarify the timeline of how modern yak breeds developed their distinctive traits suited to high-altitude survival.
