Although I mostly listen to fiction podcasts, there are a number of non-fiction things I listen to as well. One thing I recently came across, by accident, was Evolution Talk. It is such an interesting podcast where Rick Coste, that I generally think of as producing audio drama, tells us all about evolution and natural selection.
Don’t worry, it’s not heavy, complex science. It’s fun, light hearted and interesting. Even if you know nothing about evolution, it is a great place to start. But if you do know anything about it, I am certain you will learn things you didn’t know! It ran from 2014 to 2016 and has therefore ended, but if you start at the oldest episode and work forward, there are dozens fascinating episodes and lots of interesting things to learn.
