Vybarr is not only the most fabulously named babble guest we’ve had, but also the author of TWO incredible books about humans and our environment.

His new book – Primate Change: How the world we made is remaking us – uncovers the extraordinary tale of how our environment has changed our bodies, from our eyes and teeth down to our toes, while 2017’s Footnotes: How running makes us human reconnects us to our bodies and the places in which we live.

We pick Vybarr’s mega brain in a wide ranging chat, during which – as well as discovering how the treadmill killed Oscar Wilde – we learn that Dave is in fact no more than 25% Dave.

And poo transplants get a mention.
