About this episode

What if there were a great ape species that could live over 1,000 years? That’s basically Heliconius in the butterfly world. The insects live around 25 times longer than their butterfly cousins, and scientists think they have one clue as to why: pollen. But as Katie Wu , a science writer at The Atlantic , explains, that’s not the whole story. She and host Nate Rott also talk about how bats sip from the fountain of youth – and what it all may mean for humans. Read Katie's full story here .
