Synopsis

Discover the unexpected diversity, beauty, and strangeness of life in ancient lakes — some millions of years old — and the remarkable insights they yield about the causes of biodiversity. Most lakes are less than 10,000 years old and short-lived, but there is a much smaller number of ancient lakes, tectonic in origin and often millions of years old, that are scattered across every continent but Antarctica: Baikal, Tanganyika, Victoria, Titicaca, and Biwa, to name a few. Often these lakes are filled with a diversity of fish, crustaceans, snails, and other creatures found nowhere else in the world. In Our Ancient Lakes, biology professor Jeffrey McKinnon introduces the remarkable living diversity of these aquatic bodies to the general reader and explains the surprising, often controversial, findings that the study of their faunas yield about the formation and persistence of species. Shining a light on a class of biodiversity hot spot equivalent to coral reefs in the ocean or tropical rainforests on land, Our An
