This funny, "extraordinary and thought-provoking" (The Wall Street Journal) book asks whether we are in fact the superior species. As it turns out, the truth is stranger—and far more interesting—than we have been led to believe. If Nietzsche Were a Narwhal overturns everything we thought we knew about human intelligence, and asks the question: would humans be better off as narwhals? Or some other, less brainy species? There’s a good argument to be made that humans might be a less successful animal species precisely because of our amazing, complex intelligence.
