Epigenetics can potentially revolutionize our understanding of the
structure and behavior of biological life on Earth. It explains why
mapping an organism's genetic code is not enough to determine how it
develops or acts and shows how nurture combines with nature to engineer
biological diversity. Surveying the twenty-year history of the field
while also highlighting its latest findings and innovations, this volume
provides a readily understandable introduction to the foundations of
epigenetics.
Nessa Carey, a leading epigenetics researcher, connects the field's
arguments to such diverse phenomena as how ants and queen bees control
their colonies; why tortoiseshell cats are always female; why some
plants need cold weather before they can flower; and how our bodies age
and develop disease. Reaching beyond biology, epigenetics now informs
work on drug addiction, the long-term effects of famine, and the
physical and psychological consequences of childhood trauma. Carey
concludes with a discussion of the future directions for this research
and its ability to improve human health and well-being.
