Summary

Plants are delicious, nutritious, and full of energy, so they’re prime targets for all sorts of herbivores, parasites, and pathogens. But plants aren’t just sitting passively accepting attacks, they use a variety of strategies to defend themselves, from the frustrating to the fatal. This episode, we’re joined by our favorite paleobotanist, Aly Baumgartner, to discuss the many ways plants defend themselves – physically, chemically, and beyond – and the fascinating evolutionary history of plant defenses and their offenders. In the news: deep-sea fish, Wollemi pines, learning birds, and plant technology.

1:13.5	Yes. So anyone listening to the herbivores episode wondering, I wonder how plants feel about that.
1:17.8	That's what this episode is about. That's this episode. We'll talk about what plants do, what
