"So I’m thinking of trying live birth in the tsetse fly.”

"What? Why? What’s wrong with laying eggs like all the other insects?"

"I don’t know, it just seems so inefficient. You go to all the trouble of making eggs, and then most of them just get squished or frozen or eaten for dinner before they can even develop. Why not just pop out a whole larva once a week and then be done with it?"

"Once a week?”

"Well, yeah, they’ve got to keep up with the egg-layers somehow."

"Gross, evolution."

"Miraculous, you mean."
