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

This book formulates a relativistic theory of biology, challenging the common gene-centred view of organisms.

A New York Times Notable Book of 2014 We are doomed to repeat history if we fail to learn from it, but how are we affected by the forces that are invisible to us? What role does Neanderthal DNA play in our genetic makeup? How did the theory of eugenics embraced by Nazi Germany first develop? How is trust passed down in Africa, and silence inherited in Tasmania? How are private companies like Ancestry.com uncovering, preserving and potentially editing the past? In The Invisible History of the Human Race, Christine Kenneally reveals that, remarkably, it is not only our biological history that is coded in our DNA, but also our social history. She breaks down myths of determinism and draws on cutting - edge research to explore how both historical artefacts and our DNA tell us where we have come from and where we may be going.
