Animal colouration is fascinating! Conspicuously affected by natural selection, an animal's colour pattern can impact many aspects of its life: from how well it can attract a mate to its success at avoiding predation. Of course, they can also be incredibly beautiful. In this episode, we hear from Dr Jake Morris (University College London – UCL) about his recent research investigating the genetic basis of wing patterns in the postman butterfly (Heliconius melpomene): a delicate, visually striking, toxic mimic found across South and Central America.
