Quote: Just think of the advantage that the first warm-blooded mammal would have had at night, all the reptiles cooled down to somnolence unable to defend themselves. And all because of an abnormally inefficient animal (by cold-blooded standards!) that wasted energy by metabolizing food when it wasn’t needed for movement. But this kept body temperature up and so the animal was pleasantly surprised by all the sleepy prey he encountered, which more than made up for all the wasted energy. The next time that you hear an evolutionary argument based on efficiency, remember those profligate warm-blooded animals. — William H. Calvin (1939-) American theoretical neurophysiologist; The River That Flows Uphill {1986}
