Scientific American associate news editor Allison Parshall discusses the resurgence of the truly wild Przewalski's horse, once considered extinct, with successful conservation efforts. Topics include the unique features of the breed, recent online trends, cloning, and reintroduction efforts in Kazakhstan.
Przewalski's horses have unique genetic diversity, including being cloned for conservation efforts.
Conservation efforts successfully reintroduced Przewalski's horses to their native habitats, benefiting ecosystems and biodiversity.

The Unique Przewalski's Horse
Przewalski's horses are distinct from domesticated horses with different behavior and appearance. Descended from a small gene pool, efforts to preserve genetic diversity included cloning them. Despite having unique features like a thick mane and distinct neck, their behavior reflects their wild nature being uncomfortable around humans even when raised in captivity.
Conservation and Reintroduction Efforts
Przewalski's horses faced extinction in the wild due to hunting and other factors. Conservation efforts involved breeding programs to reintroduce them to their native habitats. Successful reintroduction has seen them thriving in Mongolia, China, Russia, and even in the Chernobyl exclusion zone. Challenges like genetic bottleneck and logistical issues were tackled to establish self-sustaining populations.
Ecological Importance and Future Conservation Goals
The return of Przewalski's horses benefits ecosystems by promoting biodiversity and carbon sequestration. Their grazing behavior aids in preventing wildfires and fostering soil fertility. Reintroduction efforts aim to maintain a healthy ecosystem balance by supporting the habitat of various wildlife species. Future plans include introducing more horses to ensure a self-sustaining population and ecosystem health.
Przewalski’s horses are truly wild horses, even the ones held in captivity. They traditionally roamed the Central Asian steppes, so you can imagine everyone’s surprise when two separate accounts on TikTok claimed to have found a Przewalski’s horse here in the U.S. But as guest and Scientific American associate news editor Allison Parshall will tell you, the real story is the remarkable conservation efforts that led to a resurgence for this horse, which was once considered extinct in the wild.
