Scientific knowledge has played a key role in shaping our material world, and especially with regard to genetics, our social, political and spiritual lives also. But how dependant is scientific knowledge on historical accident and chance? Could we have a different, and not necessarily less valid, version of scientific truth if history had played out slightly differently – if certain observations had been made or missed, if individual scientists had been more or less successful, if different accidents had occurred? Or, does the scientific method act to eliminate the effects of historical chance, and our present state of knowledge is somehow necessarily true? Unlikely Objects explores these questions through a “Choose Your Own” history of genetics, and the presentation of some more, or less, likely objects from imagined alternative histories of genetics.
