Chinese scientists have successfully decoded the chromosomal gene sequence of the rare Tibetan antelope, aiming to discover the secrets that enable them to survive at high altitudes.
On December 6, the Chinese Academy of Sciences (CAS) confirmed that researchers from the Northwest Plateau Institute of Biology under CAS and Qinghai University have completed decoding this gene sequence. This is considered the most accurate and comprehensive gene sequence of the Tibetan antelope to date.

The Tibetan antelope plays a crucial role in maintaining biodiversity in the Qinghai-Tibet Plateau. Researcher Zhang Tongzuo stated that this achievement not only marks a technical advancement in the genetic study of the Tibetan antelope but also provides an important foundation for biodiversity conservation efforts in the region.
He explained that analyzing the gene sequence of the Tibetan antelope will help predict their survival capabilities in the face of future climate change scenarios, thereby allowing for more effective conservation measures. This research also helps identify antelope populations that require special protection to maintain or enhance genetic diversity.
He emphasized: “This is especially important in preventing and controlling the spread of diseases within wild populations.”
Additionally, this gene sequence supports research into the relationships among different Tibetan antelope populations. According to Zhang Tongzuo, these insights are vital for designing appropriate conservation reserves and developing regional conservation strategies.
Since 2022, the research team has conducted extensive field surveys and closely monitored individual antelopes while decoding their gene sequences using third-generation sequencing technology.
Zhang Tongzuo stated: “By comparing the gene sequence of the Tibetan antelope with other species in the Caprinae subfamily, such as bharal and domestic sheep, we can trace their evolutionary history and explore how they have co-evolved with the plateau environment over millions of years.”
These findings not only illuminate the evolutionary mechanisms of this species but also provide important references for studying the adaptability of other high-altitude organisms.
The Tibetan antelope, with its light brown fur, inhabits the national nature reserves of Changtang in the southwestern region of the Tibet Autonomous Region, Hoh Xil in Qinghai Province, and the Altun Mountain National Nature Reserve in Xinjiang, at altitudes ranging from 3,700 to 5,500 meters. These areas are adjacent to each other. The fine undercoat of the Tibetan antelope was once heavily sought after, leading to rampant poaching in the 1980s and 1990s, threatening the survival of the species. In 1995, the population of Tibetan antelopes dwindled to approximately 50,000 to 75,000 individuals. Today, the population of Tibetan antelopes in Tibet has increased to over 300,000 individuals, and their conservation status has improved from “endangered” to “near threatened,” according to data from the local environmental and ecological protection agency. |
