The ability to suckle milk is a defining characteristic of mammals. Yet, one branch of mammals, egg-laying monotremes, which include the platypus and echidna, do not. Monotreme babies instead lap or slurp milk from patches on the mother's skin. New research by Professor Emeritus, Alfred Crompton and his faculty assistant, Catherine Musinsky, suggests suckling was part of the original mammalian package.  Science Magazine.
