Never heard of the quagga? You’re not alone. The animal, a relative of the zebra, went extinct over 100 years ago. Now, a group of scientists outside of Cape Town are bringing it back.

By concentrating them using selective breeding, we can get back animals showing the full appearance of the original quagga.” After four generations of breeding, Dr. Harley and his team said they’d done just that. These animals — quaggas 2.0 — roam Elandsberg Nature Reserve, in South Africa.

Why did the quagga become extinct? The quagga’s extinction is generally attributed to the “ruthless hunting”, and even “planned extermination” by colonists. Wild grass eating animals such as the Quagga were perceived by the settlers as competitors for their sheep, goats and other livestock.

During the next 30 years, the South African zebras were selectively bred to emphasize the quagga’s color traits and only the offspring that had quagga traits were kept in the breeding program.

Selective breeding versus natural selection Selective breeding is also known as artificial selection.

De-extinction (also known as resurrection biology, or species revivalism) is the process of generating an organism that either resembles or is an extinct species.

That lack of genes poses a huge challenge for breeders hoping to naturally reintroduce healthier traits into the population, a practice called reverse breeding, says study leader Niels Pedersen, a veterinary researcher at the University of California, Davis.
