"In the early 1900s, scientists discovered that each person belonged to one of four blood types. Now they have discovered a new way to classify humanity: by bacteria. Each human being is host to thousands of different species of microbes. Yet a group of scientists now report just three distinct ecosystems in the guts of people they have studied. Blood type, meet bug type. ... The research team, led by Peer Bork of the European Molecular Biology Laboratory in Heidelberg, Germany, found no link between what they call enterotypes and the ethnic background of the European, American, and Japanese subjects they studied. Nor could they find a connection to sex, weight, health, or age." (04/21/11)
