“Fascinating . . . Surprising entertainment” —The Wall Street Journal “Informative, playful, and impossible to put down.”—Publishers Weekly (starred review) In this lively, unexpec ted look at the hearts of animals—from fish to bats to humans—American Museum of Natural History zoologist Bill Schutt tells an incredible story of evolution and scientific progress. We join Schutt on a tour from the origins of circulation, still evident in microorganisms today, to the tiny hardworking pumps of worms and the golf-cart-sized hearts of blue whales. We visit beaches where horseshoe crabs are being harvested for their blood, which has properties that can protect humans from deadly illnesses. We learn that when temperatures plummet, some frog hearts can freeze solid for weeks, resuming their beat only after a spring thaw. And we journey with Schutt through human history, too, as he traces humanity’s cardiac fascination from the ancient Greeks and Egyptians, who believed the heart contained the soul, all the way up to modern-day laboratories, where scientists use animal hearts and even plants as the basis for many of today’s cutting-edge therapies. Pump shows us this mysterious organ in a completely new light. Show more
