If you’re reading this, there’s a very good chance you’re using one of the most incredible tools in the animal toolkit: the eye! In this episode, we discuss what’s known – and what’s suspected – about the incredible evolutionary history of the eye. How many types of eyes are there? What is an eye, anyway? Just how difficult is it to evolve something so intricate and complex? All this and more!
In the news: a giant parrot, a giant penguin, ancient RNA, and crinoid rafts.
