World’s first test-tube rhino created to bring back sub-species from extinction

When the last male Northern White Rhinoceros, 45-year-old Sudan, died in March it looked like the end of the sub-species was nigh. With only two females alive, and no breeding partners left, the rhino was functionally extinct, and just a few years away from dying out entirely.

But in a world first, scientists have created a test-tube rhino embryo from the frozen sperm of a Northern White male and the egg from a Southern White female.
