Scientists map genome of ‘Asian unicorn’ last seen in 2013
By Ryan General
Scientists have sequenced the genome of the (“Pseudoryx nghetinhensis”), one of the world’s rarest mammals, offering new hope for its conservation. Known as the “Asian unicorn” due to its rarity and distinctive appearance, the saola was last seen in the wild in Vietnam in 2013.
- Genetic divergence revealed: An international research team analyzed DNA from 26 saola specimens, revealing two genetically distinct populations that diverged between 5,000 and 20,000 years ago. Each group has lost different genetic variations, suggesting that combining individuals from both could enhance genetic diversity in a potential breeding program.
- Cautious optimism: Despite the lack of recent sightings, researchers remain hopeful. “Right now, the existence of live saolas can neither be proven nor disproven,” said Nguyen Quoc Dung of Vietnam’s Forest Inventory and Planning Institute. “There are some signs and indications that still give us hope.”
- A tool for detection: The newly mapped genome provides tools to detect saola DNA in environmental samples, potentially aiding in locating surviving individuals. Even if the species is extinct, the genetic data could support future de-extinction efforts.
