One of my favorite Radiolab episodes[1] was about just this: MOLLY: What do you think happens inside the chrysalis? JAD: I think that -- I actually have never thought about it, to be honest. MUSEUM GUEST: I don't know. I don't -- I don't understand how it works. MOLLY: Not many people have. MOLLY: Are you, like, surprised that you actually don't know? MUSEUM GUEST: Yeah, I'm surprised. I thought, like, I knew and I don't. MOLLY: Those are folks I met at the museum. JAD: Hey, hold up. Now that I've thought about it for a second, isn't it simply that the caterpillar is inside the shell, it sort of snuggles up, and then it grows a wing off of its right side and then off of its left side, and it just pops wings out? MOLLY: No. That is actually what I thought, but that's not right at all...
