How genes are not the only basis of heredity-and what this means for evolution, human life, and disease

For much of the twentieth 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.

By examining the history of the gene-centered view in modern biology and reassessing fundamental tenets of evolutionary theory, Bonduriansky and Day show that nongenetic inheritance-involving epigenetic, environmental, behavioral, and cultural factors-could play an important role in evolution. The discovery of nongenetic inheritance therefore has major implications for key questions in evolutionary biology, as well as human health.

Extended Heredity reappraises long-held ideas and opens the door to a new understanding of inheritance and evolution.

Reviews
"The most compelling and accessible account of this topic to date."---Kevin Laland, Science
"Extended Heredity [shows] how far the mainstream has shifted to include epigenetic forces alongside genes as drivers of who and what we are."---Liz Else and Simon Ings, New Scientist
"Bonduriansky & Day have written a book of great clarity, and have done so with great care. Whether you are open to the idea of non-genetic inheritance or not, this thought provoking book deserves a close reading." * Inquisitive Biologist *
"Extended Heredity (EH) has posed a challenge for twentieth and early twenty-first century 'normal' evolutionary biology, but the accumulation of models and experi-mental evidence for it obliges us to acknowledge its importance. This book . . . aims at making space for EH by systematizing its potential for explanation and prediction . . . this volume offers a particularly valuable state of the art of the literature on this important topic"---Gaelle Pontarotti; Arantza Etxeberria, History and Philosophy of the Life Sciences
