21. Przewalski’s Horse
Przewalski’s horse, the last truly wild horse species on Earth, disappeared from its native steppe in the 1960s. Thanks to global captive breeding collaborations, these sturdy horses were reintroduced to Mongolia and now once again roam free across the grasslands.
Their remarkable return is a triumph for conservation and a reminder that even species lost in the wild can reclaim their rightful place.
