The successful delivery spells hope for the related northern white rhino, which is facing extinction.

Researchers froze the fertilized eggs, taken from southern white rhinos, in hopes of preserving the near-extinct northern subspecies.

Victoria, a southern white rhino at the San Diego Zoo, was impregnated by artificial insemination on March 22 and, if all goes well, will birth the calf in summer 2019.

Only two members of the subspecies are now left alive.

A genetic library for African rhinoceros populations has helped match illegally trafficked products to individual poached animals in more than 120 criminal cases. 

Scientists plan to use in vitro fertilization to preserve a species with only three remaining members in the wild.

The last rhinoceros left in Vietnam was found killed, its horn sawed off, most likely by poachers.

Researchers generate pluripotent stem cells from two endangered species in hopes of learning more about the near-extinct animals.
