The amazing diversity of life is a result of billions of years of evolution. But how did the process of evolution begin? Nobel Prize winner Jack Szostak, a Professor of Genetics at Harvard Medical School and Distinguished Investigator at Massachusetts General Hospital, will describe how efforts to design and build very simple living cells are testing our assumptions about the nature of life, generating ideas about how life emerged from the chemistry of early Earth, and offering clues as to how modern life evolved from its earliest ancestors. Free and open to the public, Geological Lecture Hall, 24 Oxford Street. Free parking available in the 52 Oxford Street garage. Part of the Evolution Matters lecture series at The Harvard Museum of Natural History. Supported by a gift from Drs. Herman and Joan Suit.Â For more information, visit www.hmnh.harvard.edu.
