Ibis in Ancient Egypt, why zebras have stripes, and DNA & RNA in primordial soup

This week on the show Claire talks about how the bin chicken was a sacred bird in Egypt, and the Australian genetics research helping to tell this story. Chris looks at things in black and white and striped all over, by reviewing the research around why zebras have evolved stripes. And Stu discusses where DNA and RNA evolved from, and how German scientists are recreating primordial RNA creating soup!
