With the help of stem cells, some endangered species may be saved from eternal extinction.

Scientist say they have harvested the first set of stem cells from two species, Africa’s northern white rhinos and the baboon-like drill monkey, reports AFP. Eventually, the stem cells could theoretically be used to recreate these nearly-vanished animals without the need for a healthy mating pair.

Threats and destruction caused by humans — mainly poaching and loss of habitable land — has whittled down the number of northern white rhinos to only seven — yes, seven, all of which live in captivity. And past efforts to save the drill primates have failed due to the species tendency to develop diabetes when in captivity.
