CUTTING EDGE 1-05 絶滅危惧種の選定 Have you ever heard of the "quagga"? Perhaps not, but you may have seen a zebra before. (1)The zebra is a horse-like animal with 形M distinctive black and white stripes covering its body. The quagga was a member of the zebra family, brownish in colour with white stripes FOS around the neck and the front part of the body.

We can now only see their wild beauty as 3stuffed specimens. Some researchers, however, have tried to "revive" the quagga. Because of its attractive stripe pattern, the quagga has gathered much attention from those interested in animal conservation. Those who would like to see the animals walk around the savannas again have conducted the Quagga Project for over thirty years in South Africa.

Baby zebras born to a slightly quagga- like mother and father may look more like the quagga, with a 13 significantly reduced number of stripes. (4)This project has achieved a certain level of success, producing several lovely baby zebras which have striking similarities [to ] the quagga. . However, should we be happy about this? (5)While this new generation of zebras is visually impressive, it only resembles [X]
