'Amazing': New embryo made of nearly extinct rhino species

By  | 

JOHANNESBURG (AP) -- Researchers say they have successfully created another embryo of the nearly extinct northern white rhino in a global effort to keep the species alive.

Just two animals remain, and they are both female.

A statement Wednesday said that the viable embryo is the third to be created with eggs taken from the females and inseminated with frozen sperm from dead males.

The embryos are stored in liquid nitrogen to be transferred into a surrogate mother, a southern white rhino, in the coming months.

The goal is to create a herd of at least five animals that could be returned to their natural habitat, which could take decades.
