Once upon a time in South Africa, there lived a curious zebra that only had half its stripes. It was called the Quagga, and the Dutch and British colonialists didn’t know quite what to make of it, for it only had stripes on the front half of its body, and those stripes were so variable in their waviness that naturalists couldn’t be sure if there was only one species, or many. While the scientists pondered this question, the hunters kindly answered for it for them by blasting the quagga into extinction. Now there were no species!
Then, in 1971, a South African naturalist named Reinhold Rau, following a challenge proposed by German biologist Lutz Heck, decided to try to bring back the quagga, even though the last one had died in a zoo in 1840. After all, what is a quagga but a zebra with a plain brown butt? DNA analysis of quagga remains in 1980 further encouraged Rau: it turned out that the quagga was not its own species, but a sub-species of Plains Zebras. Rau embarked on his mad mission, visiting the world’s zoos and selecting Plains Zebras to breed. Finally, in 2005, a foal named Henry was born with the trademark quagga quirks. Party up front, business in the back. But Henry presented a new conundrum: if it walks like a quagga, and eats like a quagga, and is striped like a quagga, is it a quagga? Is it possible to recreate natural selection through artificial selection? Can you bring an extinct species back from the dead? Well, the quagga isn’t the first animal we’ve tried to put back together from missing pieces.
