The evolutionist Ernst Mayr considered August Weismann “one of the great biologists of all time.” Yet the man who formulated the germ plasm theory—that inheritance is transmitted solely through the nuclei of the egg and sperm cells—has not received an in-depth historical examination.

This cultural and ecological history explores the rise of Chesapeake’s mighty mollusk from Colonial-era harvesting to contemporary cultivation. Oysters are an essential part of Chesapeake Bay culture and cuisine, as well as the ecological and historical lifeblood of the region. When colonists first sailed these abundant shores, they described massive shoals of foot-long oysters.

Disease, environmental pressures, and overconsumption decimated the population by the end of the twentieth century. To combat the problem, Virginia began leasing its waters to private oyster farmers. Today, these boutique oyster farms are sustainably meeting the culinary demand of a new generation of connoisseurs. But in Maryland, passionate debate continues among scientists and oystermen whether aquaculture or wild harvesting is the better path. With careful research and interviews with experts, author Kate Livie presents this dynamic story and a glimpse of what the future may hold.
