Before Charles Darwin, other luminaries planted the seeds that would one day evolve into the theory that would make him famous. Author Rick Coste begins by shining a spotlight on the writers, philosophers, and scientists who planted the seeds that would blossom into the theory of evolution by natural selection, from Aristotle’s big ideas to young Mary Anning’s discovery of the first ichthyosaur skeleton. After exploring the contributions of Charles Darwin and Alfred Russel Wallace, Evolution Talk investigates the very beginnings of life itself.

Where did I come from? Why do I have two arms but just one head? How is my left leg the same size as my right one? Why are the fingerprints of identical twins not identical? How did my brain learn to learn? Why must I die? Questions like these remain biology's deepest and most ancient challenges. They force us to confront a fundamental biological problem: How can something as large and complex as a human body organize itself from the simplicity of a fertilized egg?

This pathbreaking book explores how life can begin, taking us from cosmic clouds of stardust, to volcanoes on Earth, to the modern chemistry laboratory. Seeking to understand life's connection to the stars, David Deamer introduces astrobiology, a new scientific discipline that studies the origin and evolution of life on Earth and relates it to the birth and death of stars, planet formation, interfaces between minerals, water, and atmosphere, and the physics and chemistry of carbon compounds.

Without our domesticated plants and animals, human civilization as we know it would not exist. We would still be living at subsistence level as hunter-gatherers if not for domestication. It is no accident that the cradle of civilization - the Middle East - is where sheep, goats, pigs, cattle, and cats commenced their fatefully intimate associations with humans.

There is a human genetic fluke that is surprisingly common, due to a change in a key pair of chromosomes. In the normal condition the two look the same, but in this disorder one is malformed and shrunken beyond recognition. The result is a shortened life span, higher mortality at all ages, an inability to reproduce, premature hair loss, and brain defects variously resulting in attention deficit, hyperactivity, conduct disorder, hypersexuality, and an enormous excess of both outward and self-directed aggression. It is called maleness.

Just over 125,000 years ago, humanity was going extinct until a dramatic shift occurred—Homo sapiens started tracking the tides in order to eat the nearby oysters. Before long, they’d pulled themselves back from the brink of extinction. The human brain, and its evolutionary journey, is unlike anything else in history. In A History of the Human Brain, Bret Stetka takes listeners through that far-reaching journey. He also tackles the question of where the brain will take us next, exploring the burgeoning con­cepts of epigenetics and new technologies like CRISPR.

From that first foray to the spread of early hominids who later became Homo sapiens, life has persisted, undaunted. A (Very) Short History of Life is an enlightening story of survival, of persistence, illuminating the delicate balance within which life has always existed, and continues to exist today. It is our planet like you’ve never seen it before. Life teems through Henry Gee’s lyrical prose - colossal supercontinents drift, collide and coalesce, fashioning the face of the planet as we know it today.

Among all life on Earth, we alone experience rich moral emotions, follow complex rules governing how we treat one another, and engage in moral dialogue. But how did human morality evolve? And can humans become morally evolved? In A Better Ape, Victor Kumar and Richmond Campbell draw on the latest research in the biological and social sciences to explain the key role that morality has played in human evolution.

Few people know much about stem cell research beyond the ethical questions raised by using embryos. But in the last decade, stem cell research has made huge advances toward eliminating some of our most intractable diseases. Now this sweeping and accessible book introduces us to this cutting-edge science, which will revolutionize medicine and change the way we think about and treat disease.

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.

Upon completing his historic work on the Human Genome Project in 2002, J. Craig Venter declared that he would sequence the genetic code of all life on earth. Thus began a fifteen-year quest to collect DNA from the world's oldest and most abundant form of life: microbes. Boarding the Sorcerer II, a 100-foot sailboat turned research vessel, Venter travelled over 65,000 miles around the globe to sample ocean water and the microscopic life within. In this book, Venter and science writer David Ewing Duncan tell the remarkable story of these expeditions and of the momentous discoveries that ensued.

The science of epigenetics has been scientifically proven to give anyone the power to change the expressions of their genes. Genes can be altered by either the external environmental or internal mental and emotional signals without altering the gene sequence itself. The protocols in this book take a person through the step-by-step process of doing it. By using the detailed processes given, anyone can send new signals to their genes to produce and manufacture the different proteins to restore health, gain new strength, and extend life expectancy.

Revealing how panspermia offers answers to some of humanity’s longstanding questions about the origins of life, the authors discuss the impact this shift in understanding will have on our relationship with the Earth and on culture, history, and religion. And perhaps the most dramatic ramification of all is that acceptance of panspermia means acceptance that Earth is not unique - that other life-filled planets exist and intelligent life is common in the Universe. Not only did we come from space, but we are not alone.

For millennia plant and animal species have received little sustained attention as subjects of Christian theology and ethics in their own right. Focused on the human dilemma of sin and redemptive grace, theology has considered the doctrine of creation to be mainly an overture to the main drama of human being`s relationship to God. What value does the natural world have within the framework of religious belief?

For centuries, people have been returning to the same tired nature-versus-nurture debate, trying to determine what we learn and what we inherit. In Dancing Cockatoos and the Dead Man Test, biologist Marlene Zuk goes beyond the binary and instead focuses on interaction, or the way that genes and environment work together. Driving her investigation is a simple but essential question: How does behavior evolve?

In this witty, fact-packed A-Z, Newman takes the listener on a whirlwind tour from caring, sharing vampire bats to intelligent slime mould; from pacifist baboons to Richard Dawkins wrestling naked with his postman; from the invisibility cloak of the Hawaiian bobtail squid to Francis "DNA" Crick's belief that life on Earth began with alien spaceships.

Charles Darwin’s theory of evolution now forms the basis for all the life sciences, but it ignited widespread controversy upon its 1859 publication. The idea that humans and animals might have evolved from a common source came as a shock to readers at the time, and people struggle with the implications of Darwin’s theory to this day. But Darwin foresaw this resistance and argued his case with extensive examples and rigorous logic - and his theory continues to push us toward a deeper understanding of life on Earth.

Resistance to malaria. Blue eyes. Lactose tolerance. What do all of these traits have in common? Every one of them has emerged in the last 10,000 years.

From the cup of coffee that jump-starts the day to dangerously addictive drugs, the recreational use of plants with psychoactive properties has a long history among humans. But, as with many things, it turns out that other animals got there first. From parrots to primates, consuming medicinal chemicals is an instinctive behavior that helps countless organisms fight infection and treat disease. But the similarities don't end there: Like us, many creatures also consume substances that have no apparent benefit...except for inducing intoxication.

A new gene editing technology, invented just seven years ago, has turned humanity into gods. Enabling us to manipulate the genes in virtually any organism with exquisite precision, CRISPR has given scientists a degree of control that was undreamt of even in science fiction. But CRISPR is just the latest, giant leap in a long journey to master genetics. The Genetic Age shows the astonishing, world-changing potential of the new genetics and the possible threats it poses, sifting between fantasy and the reality when it comes to both benefits and dangers.
