From the hilarious and world famous blog of the same name comes WTF, Evolution? A four-colour impulse book with more than 100 photographs of the world's weirdest, wackiest creatures. Hilarious text accompanying the photos portrays Evolution as a character who proceeds clumsily and without direction, testing out every half-baked or ill-advised idea it comes up with until one of them finally sticks. This haphazard methodology produces creatures like the emperor tamarin, a monkey with a moustache bigger than its face (apparently made during Evolution's hipster phase); the flannel moth, which, as a larva, looks convincingly like Donald Trump's hair; the macaque, endowed with an enormous pink butt; spiders made to look like bird poop; and a warty pig with a blue rocker mohawk. Much additional sidebar material is incorporated throughout, such as: special features on plants and extinct animals, top ten lists (e.g., weirdest noses of all time), letters from evolution throughout history in the style of explorer's logs, passive aggressive (okay, sometimes aggressive) notes to evolution from disgruntled creatures, and other miscellany. WTF, Evolution? captures the sweetness of Unlikely Friendships, the awkwardness of Awkward Family Photos, and the real science and humorous bent of Why Do Men Have Nipples?
