Genetic differences can influence differences in our human behaviours, but only occasionally undermine the reality of our free will.
How does genetic variation impact on behavioural differences and how does this relate to free will and personal identity? Denis Alexander examines these questions.
Why do we behave the way we do? Biologist Paul Ehrlich suggests that although people share a common genetic code, these genes "do not shout commands at us...at the very most, they whisper suggestions." He argues that human nature is not so much result of genetic coding; rather, it is heavily influenced by cultural conditioning and environmental factors. With personal anecdotes, a well-written narrative, and clear examples, Human Natures is a major work of synthesis and scholarship as well as a valuable primer on genetics and evolution that makes complex scientific concepts accessible to lay readers.
From acclaimed author and researcher Dr. Joy DeGruy comes this fascinating book that explores the psychological and emotional impact on African Americans after enduring the horrific Middle Passage, over 300 years of slavery, followed by continued discrimination. From the beginning of American chattel slavery in the 1500’s, until the ratification of the Thirteenth Amendment in 1865, Africans were hunted like animals, captured, sold, tortured, and raped. They experienced the worst kind of physical, emotional, psychological, and spiritual abuse. Given such history, Dr. Joy DeGruy asked the question, “Isn’t it likely those enslaved were severely traumatized? Furthermore, did the trauma and the effects of such horrific abuse end with the abolition of slavery?” Emancipation was followed by another hundred years of institutionalized subjugation through the enactment of Black Codes and Jim Crow laws, peonage and convict leasing, and domestic terrorism and lynching. Today the violations continue, and when combined with the crimes of the past, they result in further unmeasured injury. What do repeated traumas visited upon generation after generation of a people produce? What are the impacts of the ordeals associated with chattel slavery, and with the institutions that followed, on African Americans today? Dr. DeGruy answers these questions and more as she encourages African Americans to view their attitudes, assumptions, and emotions through the lens of history. By doing so, she argues they will gain a greater understanding of the impact centuries of slavery and oppression has had on African Americans. Post Traumatic Slave Syndrome is an important read for all Americans, as the institution of slavery has had an impact on every race and culture. “A masterwork. [DeGruy’s] deep understanding, critical analysis, and determination to illuminate core truths are essential to addressing the long-lived devastation of slavery. Her book is the balm we need to heal ourselves and our relationships. It is a gift of wholeness.”—Susan Taylor, former Editorial Director of Essence magazine
The New York Times bestseller – with a new afterword about early specialization in youth sports – from the author of Range: Why Generalists Triumph in a Specialized World. The debate is as old as physical competition. Are stars like Usain Bolt, Michael Phelps, and Serena Williams genetic freaks put on Earth to dominate their respective sports? Or are they simply normal people who overcame their biological limits through sheer force of will and obsessive training? In this controversial and engaging exploration of athletic success and the so-called 10,000-hour rule, David Epstein tackles the great nature vs. nurture debate and traces how far science has come in solving it. Through on-the-ground reporting from below the equator and above the Arctic Circle, revealing conversations with leading scientists and Olympic champions, and interviews with athletes who have rare genetic mutations or physical traits, Epstein forces us to rethink the very nature of athleticism.

Charles Darwin played a crucial part in turning heredity into a scientific question, and yet he failed spectacularly to answer it. The birth of genetics in the early 1900s seemed to do precisely that. Gradually, people translated their old notions about heredity into a language of genes. As the technology for studying genes became cheaper, millions of people ordered genetic tests to link themselves to missing parents, to distant ancestors, to ethnic identities... But, Zimmer writes, “Each of us carries an amalgam of fragments of DNA, stitched together from some of our many ancestors. Each piece has its own ancestry, traveling a different path back through human history. A particular fragment may sometimes be cause for worry, but most of our DNA influences who we are—our appearance, our height, our penchants—in inconceivably subtle ways.” Heredity isn’t just about genes that pass from parent to child. Heredity continues within our own bodies, as a single cell gives rise to trillions of cells that make up our bodies. We say we inherit genes from our ancestors—using a word that once referred to kingdoms and estates—but we inherit other things that matter as much or more to our lives, from microbes to technologies we use to make life more comfortable. We need a new definition of what heredity is and, through Carl Zimmer’s lucid exposition and storytelling, this resounding tour de force delivers it. Weaving historical and current scientific research, his own experience with his two daughters, and the kind of original reporting expected of one of the world’s best science journalists, Zimmer ultimately unpacks urgent bioethical quandaries arising from new biomedical technologies, but also long-standing presumptions about who we really are and what we can pass on to future generations.
Matt Ridley explores such perplexing conundrums as why, if humans are such egoistical beings, don't they behave as rational fools and forego the benefits of cooperation. He uses the findings of new research to look afresh at "Mankind".
