Special documentary following the studies of Dr. William Barklow, a bio-acoustic researcher who assesses how hippos communicate with each other. Revolutionary findings have led scientists to believe that modern dolphins and whales could have descended from a common ancestor, a water-lover such as the hippo. Using tests both in the controlled environment of an American zoo and the wild rivers and pools of Zambia and Kenya, Dr. Barklow reveals groundbreaking observations.
