In the late 1800s, a Russian explorer described a breed of Mongolian horse
previously unknown to science. This breed, known in Mongolia as takhi, ceased
to exist in the wild by the 1960s. Fortunately, by then some captured takhi had been
taken to breeding reserves in Europe. This action saved the small but hardy breed
from becoming extinct. The breed was later reintroduced to Mongolia, where now
several hundred takhi live on a nature reserve.
