Albatross pairs mate for life. Garter snakes mate in 100+ orgies. Whether you were together, apart or alone this Valentine’s day, our tales of love in the wild will send you swooning. We describe the different ways animals show their affections, the many hormones which make us addicted to each other and the promiscuous past of humans. Did you know that there is a sexual arms race amongst male and female ducks? Have you ever lied restless in bed thinking about the wording of a message?

We really hope you enjoy the episode. If you want to support two humble young scientists, follow the show on Spotify or subscribe to it on Apple Podcasts, and leave a review if you can.
