'Are You A Model?': Crickets Are So Hot ...

NPR
About this episode
Have you ever wondered how biologists choose what animal to use in their research? Since scientists can't do a lot of basic research on people, they study animals to shed light on everything from human health to ecosystems to genetics. And yet, just a handful of critters appear over and over again. Why the mouse? Or the fruit fly? Or the zebrafish?

Cassandra Extavour, an evolutionary biologist at Harvard, talked with Short Wave co-host Aaron Scott about her favorite new model critter on the block: crickets. (Well, "favorite" might be a strong word. As Cassandra concedes, "to be honest, my opinion about crickets is sort of neutral to slightly grossed out.")

On today's episode we leave the mouse to its maze, and instead consider the cricket and all the amazing things it can teach us.
