Welcome to BioAudio: The Teaching Podcast. After many years teaching biology in universities in the UK and in Canada I've come to the conclusion that we can do better than text books. I always want something more flexible, that can be updated with new topics and new discoveries. After years avoiding textbooks… I've created BioAudio a collection of discussions to accompany lectures in university biology courses . So let's ditch the textbook and just listen.

What's a species, the strange case of the salamanders

Episode 16
The Ambsystoma salamanders of the great lakes region have the most peculiar mating system.. they are all females, but they steal the genomes from other related species to aid in reproduction. This "kleptogenesis" is ancient, probably originating 5 million years ago. This makes it a stable reproductive strategy but it defies everything the text books tell us about species boundaries. In this episode Prof Katty Greenwald and I talk about what makes a species and how vague the term can really be.
