This week the Natural Selection found out it's not easy being green.. well not if you’re a mammal anyway. This week we talked all about the colour green and how and why some animals and most plants are green. Why aren’t there any green mammals? How does chlorophyll work? What is that green bird in Hyde park? Listen now to find out more!

Next week we're going to take a small break but we'll be back on the 3rd of August. Thanks for listening
