30-Year Experiment Shows Evolution in Slow Motion | In 1988, toxic algae wiped out a population of rough periwinkle sea snails in Sweden. An ecologist re-introduced 700 snails of a different ecotype in 1992. Over 30 years, the colonists evolved down a strikingly similar pathway to their predecessors
