Book Description
The Minnesota Study of Twins Reared Apart startled scientists by demonstrating that twins reared apart are as alike, across a number of personality traits and other measures, as those raised together, suggesting that genetic influence is pervasive. Segal offers an overview of the study’s scientific contributions and effect on public consciousness.

Book Description
The identical “Jim twins” were raised in separate families and met for the first time at age thirty-nine, only to discover that they both suffered tension headaches, bit their fingernails, smoked Salems, enjoyed woodworking, and vacationed on the same Florida beach. This example of the potential power of genetics captured widespread media attention in 1979 and inspired the Minnesota Study of Twins Reared Apart. This landmark investigation into the nature-nurture debate shook the scientific community by demonstrating, across a number of traits, that twins reared separately are as alike as those raised together. As a postdoctoral fellow and then as assistant director of the Minnesota Study, Nancy L. Segal provides an eagerly anticipated overview of its scientific contributions and their effect on public consciousness. The study’s evidence of genetic influence on individual differences in traits such as personality (50%) and intelligence (70%) overturned conventional ideas about parenting and teaching. Treating children differently and nurturing their inherent talents suddenly seemed to be a fairer approach than treating them all the same. Findings of genetic influence on physiological characteristics such as cardiac and immunologic function have led to more targeted approaches to disease prevention and treatment. And indications of a stronger genetic influence on male than female homosexuality have furthered debate regarding sexual orientation.

Book Description
The combination of a riveting true story and cutting-edge twin research makes this book an irresistible page-turner. Identical twins Begoña and Delia were born thirty-eight years ago in Spain’s Canary Islands. Due to chaotic conditions at the hospital or simple human error, the unthinkable happened: Delia was unintentionally switched with another infant in the baby nursery. This fascinating story describes in vivid detail the consequences of this unintentional separation of identical twin sisters. The author considers not only the effects on these particular sisters, but the important implications of this and similar cases for questions concerning identity, familial bonds, nature-nurture, and the law.

Book Description
"A unique window into human behavior and development." —Steven Pinker The riveting story of two sets of identical twins separated at birth and improbably reunited as adults, a dream case for exploring nature and nurture. Accidental Brothers tells the unique story of two sets of identical Colombian twin brothers who discovered at age 25 that they were mistakenly raised as fraternal twins—when they were not even biological brothers. Due to an oversight that presumably occurred in the hospital nursery, one twin in each pair was switched with a twin in the other pair. The result was two sets of unrelated “fraternal” twins—Jorge and Carlos, who were raised in the lively city of Bogotá; and William and Wilber, who were raised in the remote rural village of La Paz, 150 miles away. Their parents and siblings were aware of the enormous physical and behavioral differences between the members of each set, but never doubted that the two belonged in their biological families. Everyone’s life unraveled when one of the twins—William—was mistaken by a young woman for his real identical twin, Jorge. Her “discovery” led to the truth—that the alleged twins were not twins at all, but rather unrelated individuals who ended up with the wrong families. Blending great science and human interest, Accidental Brothers by Nancy L. Segal and Yesika S. Montoya will inform and entertain anyone interested in how twin studies illuminate the origins of human behavior, as well as mother-infant identification and the chance events that can have profound consequences on our lives.

Book Description
Journalist Abigail Pogrebin is many things—wife, mother, New Yorker—but the one that has defined her most profoundly is “identical twin.” As children, she and her sister, Robin, were inseparable. But when Robin began to pull away as an adult, Abigail was left to wonder not only why, but also about the very nature of twinship. What does it mean to have a mirror image? How can you be unique when somebody shares your DNA? In One and the Same, Abigail sets off on a quest to understand how genetics shape us, crisscrossing the country to explore the varied relationships between twins, which range from passionate to bitterly resentful. She speaks to the experts and tries to answer the question parents ask most—is it better to encourage their separateness or closeness? And she paints a riveting portrait of twin life, yielding fascinating truths about how we become who we are.

Book Description
A New York Times Notable Book for 1998 Critical acclaim for Lawrence Wright's A Rhone-Poulenc Science Prize Finalist "This is a book about far more than twins: it is about what twins can tell us about ourselves."—The New York Times "With plenty of amazing stories about the similarities and differences of twins, Wright respectfully shows, too, how their special circumstance in life challenges our notions of individuality. A truly fascinating but sometimes spooky (Mengele's experiments with twins at Auschwitz figure among Wright's examples) study."—American Library Association "Like so much of Wright's work, this book is a pleasure to read. Because he writes so well, without pushing a particular point of view, he soon has you pondering questions you have tended to comfortably ignore."—Austin American-Statesman "Informative and entertaining . . . a provocative subject well considered by a talented journalist."—Kirkus Reviews
