One hundred episodes is kind of a big deal, so we figured we’d pick a big deal kind of topic, and it doesn’t get much bigger than this.
As far as we can tell, all life on Earth is descended from a common ancestry – at some point, at least once, life originated on Earth. But when, where, and how? These are open questions that have been subject to lots of scientific and philosophical discussions and experiments. In this episode, we’ll touch on some of the biggest questions: What even is life? How old is life on Earth? What steps led to the first living things? Is Earth the only place this has happened?
In the news: dino bone disease, amphibian chameleons, ancient social mammals, and pterosaur diets.
