Description
Species evolve over time to become perfectly adapted to their environments, right?Well, sometimes. Consider that an elephant will not grow a seventh set of teeth, even though wearing down the sixth will condemn it to starvation; that hosts of the European cuckoo seem unable to tell that the overgrown monster in their nest is not their own chick; and that whales are fully aquatic mammals who, millions of years after first abandoning the land, still cannot breathe underwater. This book is about evolution, but not its greatest hits.
