In Born in Africa, Martin Meredith follows the trail of discoveries about human origins made by scientists over the last hundred years, recounting their intense rivalry, personal feuds, and fierce controversies, as well as their feats of skill and endurance. The results have been momentous. Scientists have identified more than 20 species of extinct humans. They have firmly established Africa as the birthplace not only of humankind but also of modern humans.

It is widely understood that Charles Darwin’s theory of evolution completely revolutionized the study of biology. Yet, according to David Sloan Wilson, the Darwinian revolution won’t be truly complete until it is applied more broadly - to everything associated with the words “human,” “culture,” and “policy.”

In Arrival of the Fittest, renowned evolutionary biologist Andreas Wagner draws on over 15 years of research to present the missing piece in Darwin's theory. Using experimental and computational technologies that were heretofore unimagined, he has found that adaptations are not just driven by chance, but by a set of laws that allow nature to discover new molecules and mechanisms in a fraction of the time that random variation would take.

Inevitably, life on Earth will come to an end, whether by climate disaster, cataclysmic war, or the death of the sun in a few billion years. To avoid extinction, we will have to find a new home planet, perhaps even a new solar system, to inhabit. In this provocative and fascinating book, Christopher Mason argues that we have a moral duty to do just that.

In Dinosaurs Rediscovered, leading paleontologist Michael J. Benton gathers together all the latest paleontological evidence, tracing the transformation of dinosaur study from its roots in antiquated natural history to an indisputably scientific field. Among other things, the book explores how dinosaur remains are found and excavated, and especially how paleontologists read the details of dinosaurs' lives from their fossils - their colors, their growth, and even whether we will ever be able to bring them back to life.

Edward O. Wilson is one of the world’s preeminent biologists, a Pulitzer Prize winner, and the author of more than 25 books. The defining work in a remarkable career, The Social Conquest of Earth boldly addresses age-old questions (Where did we come from? What are we? Where are we going?) while delving into the biological sources of morality, religion, and the creative arts.

In 2018, scientists manipulated the DNA of human babies for the first time. As biologist and historian Matthew Cobb shows in As Gods, this achievement was one many scientists have feared from the start of the genetic age. Four times in the last fifty years, geneticists, frightened by their own technology, have called a temporary halt to their experiments. They ought to be frightened.

James D. Watson, the Nobel laureate whose pioneering work helped unlock the mystery of DNA's structure, charts the greatest scientific journey of our time, from the discovery of the double helix to today's controversies to what the future may hold. Updated to include new findings in gene editing, epigenetics, and agricultural chemistry as well as two entirely new chapters on personal genomics and cancer research. This is the most comprehensive and authoritative exploration of DNA's impact on our society and our world.

This audiobook takes you on an exciting journey into the past to uncover the story of the Denisovans. Hidden deep in the Denisova Cave in Siberia, their remains went unnoticed for centuries. But when scientists discovered them, it changed what we knew about human history.

Award-winning author, Stephen Hawley Martin, spent three years interviewing more than one hundred experts, ranging from noted quantum physicist, Henry Stapp, Ph.D., to the Director of the Windbridge Institute, Julie Beischel, Ph.D., to the Director of the Division of Perceptual Studies [DOPS] at the University of Virginia School of Medicine, Jim B. Tucker, M.D. The topics covered included research into near death experiences [NDEs], research into veracity of reports by psychic mediums, research concerning ESP and documented paranormal activity as well as children’s memories of past lives ...

Everywhere there are characteristics of animals that do not want to fit into the theory of evolution anywhere. And man? Are we really the most adapted life-form on this planet? Today, more and more scientists who contradict the previous theory of evolution speak out. The theory fits the changes within the species, but it can no longer be reconciled with the inner workings of the cell. Some other influence that has so far escaped us is affecting evolution. It is called "Intelligent Design." Intelligent planning is suspected behind this.

Since the publication in 1859 of Charles Darwin's remarkable On the Origin of Species, the modern science of biology and genetics has added surprising new dimensions to evolutionary theory. In this course, you’ll discover what Darwin didn’t know, covering much of the curriculum of an introductory college course in evolutionary biology. No background in science is needed to follow these engaging lectures, delivered by Professor Scott Solomon of Rice University, a gifted teacher and widely traveled field biologist.

A scientific and medical revolution has crept up on us, based on study after study, from hundreds of laboratories around the world. It is no longer just a theoretical shift: every one of us will be touched by it, and many of us already have been. The meaning of disease, our understanding of the human body, and crucial decisions about what we all need to know and what choices we make about our health are at stake. Welcome to the new world of personalized medicine.

Brains Through Time examines how vertebrate nervous systems evolved in conjunction with other organ systems and the planet's ecology. Surveying an enormous range of information on genes and proteins, sensory and motor systems, central neural circuits, physiology, and animal behavior, the authors reconstruct the major changes that occurred as vertebrates emerged and then diversified.

Once, we humans could only observe evolution. Suddenly, we had conquered it. And yet, in Life as We Made It, evolutionary biologist Beth Shapiro argues that - despite how amazing our new technologies are - our ability to alter the course of evolution isn’t new. What is new is that where once we shaped evolution through brute force, we can now do it as artisans. That power comes not a moment too soon. If we are going to survive in the next few centuries, we must revise the book of life.

For a long time, scientists have wondered how life has emerged from inanimate chemistry, and whether Earth is the only place where it exists. Charles Darwin speculated about life on Earth beginning in a warm little pond. Some of his contemporaries believed that life existed on Mars. It once seemed inevitable that the truth would be known by now. It is not. For more than a century, the origins and extent of life have remained shrouded in mystery. But, as Mario Livio and Jack Szostak reveal in Is Earth Exceptional?, the veil is finally lifting.

In The Ancestor's Tale, evolutionary biologist Richard Dawkins offers a masterwork: an exhilarating reverse tour through evolution, from present-day humans back to the microbial beginnings of life four billion years ago. Throughout the journey, Dawkins spins entertaining, insightful stories and sheds light on topics such as speciation, sexual selection, and extinction. The Ancestor's Tale is at once an essential education in evolutionary theory and riveting in its telling.

For decades Richard Dawkins has been the world's most brilliant scientific communicator, consistently illuminating the wonders of nature and attacking faulty logic. Science in the Soul brings together 42 essays, polemics, and paeans - culled from personal papers, newspapers, lectures, and online salons - all written with Dawkins' characteristic erudition, remorseless wit, and unjaded awe of the natural world.

Understanding the basis of making moral choices is crucial as society becomes increasingly complex. Moral Choices: An Introduction to Ethics gives college students a solid grounding in both theory of ethics and its applications to the social issues of today. Avoiding undue dogmatism, Professor Scott B. Rae outlines the distinctive elements of Christian ethics.

Author Brian Switek is a charming and enthusiastic osteological raconteur. In this natural and cultural history of bone, he explains where our skeletons came from, what they do inside us, and what others can learn about us when these wondrous assemblies of mineral and protein are all we've left behind.
