text:  This is Science Friday. I'm Rasha Aridi. And I'm Aja Drain. We're looking back at the history and science of panda conservation. During the 2000s, scientists were finally getting the hang of captive breeding. In the earlier days, scientists actually had to capture wild pandas and bring them into breeding centers so they could make more babies. But with so many more cubs being born in captivity, scientists didn't need to wrangle the wild ones anymore. In fact, they could start releasing the ones born in captivity.
