Nature's Rainbow

It's our thoroughly non-Christmassy Christmas episode, and the last Fuzzy for 2016, so we're talking about colour in nature. Why are animals colourful? How did yellow patterns come to mean "please don't eat me, I'm poisonous, I promise" and how did tricksters come to mimic those patterns for their own ends? Eleanor is joined in the studio by Thomas, (a biochemistry PhD student with an encyclopedic knowledge of the natural world and a penchant for awful puns), and Mitchell, who was probably a dinosaur in a previous life. Enjoy, and Happy New Year from Fuzzy!
