Evolution has led to a diverse array of wildlife — and many creatures are rarely seen by humans. In the new book "WTF, Evolution?! A Theory of Unintelligible Design" (Workman, October 2014), author Mara Grunbaum has selected more than 100 of the oddest, most unusual of those creatures and asks of the character Evolution: "What were you thinking?"

Some interesting reading material
A cutie pie
The piglet squid would seem to suggest that Evolution's medications are working. Possibly a little too well.
An odd frog
Really, Evolution? You've had 130 million years to work on the pignose frog, and this is the best you could do? Did you maybe boil it too long?
A zombie fish
Dark thoughts keep Evolution awake some nights. It tosses and turns for hours, tormented by visions of creatures too twisted for anyone else to see — creatures that it knows no decent natural force would ever even imagine. In a desperate attempt to feel normal, Evolution tries to bury these demons deep within the murky sand. Damn things keep poking their heads back out to eat, though.
A worm? a robot?
"Okay, this is it. I just came up with the greatest animal yet."
"This should be good."
"It's called a tardigrade. It's only half a millimeter long, so it's basically invisible."
"It has sharp claws for grabbing onto anything and a suction mouth for feeding."
"But here's the cool part: It can survive pretty much anything! Drying out? Freezing? Extreme radiation? It doesn’t care. It just hunkers down and waits it out, then pops back to life later on."
"Huh. I guess that's kinda cool."
"And it can even survive in the vacuum of outer space."
"What? Why would it possibly need to survive in outer space?"
"You never know."
An unfortunate accident
Evolution accidentally dropped his bat on the floor but was too embarrassed to say anything so just pretended it was actually supposed to look like that.
Need a shave?
Hey, Evolution, I know that beards are in and all, but I think you may have put this pig's beard on backward. Or upside down. Or inside out? Possibly all three.
Hey, Evolution, do you think you forgot something here? Like, I don't know, the entire back half of the fish?
What'd you say?
"Good lord, Evolution, what is that?"
"It’s a 'tapir.' Get it?"
"I don’t get it."
"Come on! A TAPIR!"
"This isn't helping."
"It's a tapir! It has a tapered nose! Tapir!"
Is this a unicorn?
Why so gloomy, babirusa? Is it because Evolution gave you some weird extra tusks that are ugly, useless, too brittle to fight with, and may eventually grow so long that they curve around and fatally puncture your skull? Could that be it?
