Extended Heredity: A New Understanding of Inheritance and Evolution

For much of the 20th century it was assumed that genes alone mediate the transmission of biological information across generations and provide the raw material for natural selection.

In 'Extended Heredity', leading evolutionary biologists Russell Bonduriansky and Troy Day challenge this premise.

Drawing on the latest research, they demonstrate that what happens during our lifetimes - and even our grandparents' and great-grandparents' lifetimes - can influence the features of our descendants.

On the basis of these discoveries, Bonduriansky and Day develop an extended concept of heredity that upends ideas about how traits can and cannot be transmitted across generations.
