About this ebook

Human beings have astonishing genetic vulnerabilities. More than half of us will die from complex diseases that trace directly to those vulnerabilities, and the modern world we’ve created places us at unprecedented risk from them. In It Takes a Genome, Greg Gibson posits a revolutionary new hypothesis: Our genome is out of equilibrium, both with itself and its environment. Simply put, our genes aren’t coping well with modern culture. Our bodies were never designed to subsist on fat and sugary foods; our immune systems weren’t designed for today’s clean, bland environments; our minds weren’t designed to process hard-edged, artificial electronic inputs from dawn ‘til midnight. And that’s why so many of us suffer from chronic diseases that barely touched our ancestors.

Gibson begins by revealing the stunningly complex ways in which multiple genes cooperate and interact to shape our bodies and influence our behaviors. Then, drawing on the very latest science, he explains the genetic “mismatches” that increasingly lead to cancer, diabetes, inflammatory and infectious diseases, AIDS, depression, and senility. He concludes with a look at the probable genetic variations in human psychology, sharing the evidence that traits like introversion and agreeableness are grounded in equally complex genetic interactions.

It Takes A Genome demolishes yesterday’s stale debates over “nature vs. nurture,” introducing a new view that is far more intriguing, and far closer to the truth.

About the author

Greg Gibson is Professor of Genetics at North Carolina State University in Raleigh, and of Integrative Biology at the University of Queensland, Australia. He is a leader in the new field of genomics, studying how interactions between genes and the environment affect human health and organismal evolution. He holds a Ph.D. from the University of Basel, Switzerland, and did postdoctoral work at Stanford University. He is on the editorial boards of PLoS Genetics, Current Biology, Genetics, and other leading journals, and with Spencer V. Muse, coauthored A Primer of Genome Science, one of the field’s leading textbooks, now in its third edition.
