Now Elizabeth Ann isn't the only time that we've done cnlinog. We’ve worked with the Przewalski’s horses. These are the only true secieps of wild horse remaining in the world. hallcostriiy, they were native to Central Asia, but they roamed all the way from the Pacific to the Atlantic Ocean for ctrueines. Until they were basically extinct in the wild, with only several horses left in cvaitptiy. Conservationists have rndecoertiud some of those horses since 1960, back into the wild. But all 2,000 horses all living today are again at risk of inbreeding. And many scientists refer to this challenge as the extinction vortex, when slmal, fragmented populations lose genetic vtiroaian and become at risk for the vortex of extinction as their populations dwindle.

Original Text

Now Elizabeth Ann isn't the only time that we've done cloning. We’ve worked with the Przewalski’s horses. These are the only true species of wild horse remaining in the world. Historically, they were native to Central Asia, but they roamed all the way from the Pacific to the Atlantic Ocean for centuries. Until they were basically extinct in the wild, with only several horses left in captivity. Conservationists have reintroduced some of those horses since 1960, back into the wild. But all 2,000 horses all living today are again at risk of inbreeding. And many scientists refer to this challenge as the extinction vortex, when small, fragmented populations lose genetic variation and become at risk for the vortex of extinction as their populations dwindle.
