The Big Book of Butts (Somos8)

This book has a lot of facts about butts in the animal kingdom. It has some silly illustrations and turns of phrases that make it an engaging read. I had never thought of butts in terms of having an evolutionary birthday or that it was a sign of increasing intelligence because more complex creatures were developing them in the Cambrian Period. Usually, I like nonfiction to have real photographs, when possible, yet given the topic it is much more appropriate that the illustrations are a bit cartoonish and therefore easier to incorporate humans and the culture around terminology into the discussion. The cover and title do a great job of grabbing your attention and making you curious enough to keep turning the pages to see what else it would say while giving you facts almost without realizing you are learning. Since kids are already curious about behinds it is great to get facts about them as well so the topic is demystified.
