Drinking habits of ancient whales

   SAN FRANCISCO, May 29 (UPI) -- Researchers say (Wednesday) they have
intriguing clues into the physiological modifications that ancient
whales underwent, such as the evolution of the ability to subsist on
seawater and cross oceans without access to fresh water. The development
of modern-day whales from four-footed predators that roamed the land and
perhaps looked like a wolf or hyena has long intrigued scientists as one
of the more striking examples of mammalian evolution.
