Scientists Sequence Genome of Rare ‘Asian Unicorn’ in Effort to Save Species
Researchers have successfully sequenced the genome of one of the world’s rarest animals, the ‘Asian unicorn’, also known as the saola. This elusive creature, with its distinct long horns and white facial markings, has not been sighted in over a decade, raising concerns about its extinction.
The saola, scientifically named Pseudoryx nghetinhensis, inhabits the mountainous forests of Vietnam and Laos. Despite being discovered in 1993, it has never been observed in the wild by scientists. The species is critically endangered, with only an estimated 50 to a few hundred individuals remaining.
A recent breakthrough in genetic analysis, led by an international team of scientists, has provided new hope for the saola’s survival. By reconstructing the saola genome using tissue samples from 26 individuals, researchers have uncovered valuable insights into the species’ history and potential conservation strategies.
The study revealed that the saola consists of two genetically distinct populations â northern and southern. While both populations have experienced a decline in genetic diversity over time, they have lost different sections of their genetic code. This discovery could be crucial for the species’ conservation efforts.
Biologist GenĂs Garcia Erill from the University of Copenhagen expressed surprise at the genetic differences between the two saola populations, noting that combining individuals from both groups could enhance their chances of survival.
Based on simulations conducted in the study, a captive breeding program involving a mix of individuals from both saola populations could significantly improve the species’ long-term survival prospects. However, the challenge lies in locating live specimens, as the last confirmed sighting dates back to 2013.
Zoologist Minh Duc Le from Vietnam National University highlighted the importance of the complete saola genome in aiding conservation efforts, enabling researchers to deploy advanced techniques for detecting the species.
The groundbreaking research, published in the journal Cell, offers a glimmer of hope for the ‘Asian unicorn’ as scientists strive to prevent its extinction and secure a future for this enigmatic species.
