This gives a brief and quick overview of evolutionary theories of the origins of early life at the microscopic levels and the view of how organic substances can come from inorganic substances.

This serves as the second book in the Basics of Biology series. In this segment, the functions of membranes are explored. With regards to fully understanding biological organisms, the cell membrane is essential to developing an understanding of how cell function to control the substance that enter and exit them along with they way in which they interact with their environment.

In this book, some of the basic information and background into biology is broken down and explained. This serves as a quick and fast to the point introduction to biology. Some of the concepts explored include cell structure, taxonomy, biochemistry, and systems biology. With listening to this book, one could explain some of the simpler concepts of biology in a short time.

DNA serves as the basic instruction manual for life. In this installment, we look at the way in which DNA is structured, replicated, and how it is packaged into such a small area. This will provide the basic understanding of how genes are structured in an easy to understand way.

The environment can cause - and cure - cancer! Out of the labs of the prestigious Pasteur Institute came decades of research that unlocked the mystery of cancer at the DNA level. But we're only just now finding out about it.

Why do organisms grow old and die? What are the theories of aging? Does the Free Radical Theory of Aging still stack up? How do cells decide when to divide, differentiate or die? What factors accelerate the aging process? This essay takes a look at these issues and would thus be useful to students who want to know more about the processes that control cell death. The essay also documents the more extreme measures that some people have taken in the pursuit of eternal youth.

Emmy Award - winning filmmaker, writer, and naturalist Joe Hutto has done it again. Touching the Wild is the enchanting story about one man who has lived with a herd of mule deer in the Wind River mountains of Wyoming for almost seven years. Why, you may ask, would a person choose to do such a thing? His response: how could you not? For Joe Hutto, close proximity to wild things is irresistible. In Illumination in the Flatwoods he unveiled the secret lives of the wild turkey to great critical acclaim.

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.

We remember the admonition of our mothers: "Treat others as you want them to treat you." But what if being nice was something we were inclined by nature to do anyway? Renowned neuroscientist Donald Pfaff upends our entire understanding of ethics and social contracts with an intriguing proposition: the Golden Rule is hardwired into the human brain. Pfaff, the researcher who first discovered the connections between specific brain circuits and certain behaviors, contends that the basic ethics governing our everyday lives can be traced directly to brain circuitry.

Twelve renowned scientists and theologians offer penetrating insights into the evolution dialogue in The Deep Structure of Biology. Each considers whether the orthodox model of evolution is sufficient and offers his/her own perspective on evolution and biology. The discussion of biology and evolution in these essays broadens the scope of the traditional evolution discussion as it aims to stimulate the development of further research programs. Scholars in the science and religion field will find this book a valuable resource.

Mark Moffett doesn't just study ants, he travels among them. Moffet holds a Harvard Ph.D. in entomology and is an accomplished scientist, an award-winning author and journalist, and one of the best nature photographers of his generation. Years ago, this free-spirited naturalist left academia behind to plunge into the deepest jungles and observe insect societies up close. Now author Nicholas Griffin takes us inside Moffett's own world, to explore his death-cheating quest for discovery.

Again and again, microbes have shaped our health, our genetics, our history, our culture, our politics, even our religion and ethics. This book reveals much that scientists and cultural historians have learned about the pervasive interconnections between infectious microbes and humans. It also considers what our ongoing fundamental relationship with infectious microbes might mean for the future of the human species.

Human beings have astonishing genetic vulnerabilities. More than half of us will die from complex diseases that trace directly to those vulnerabilities, and the modern world we've created places us at unprecedented risk from them. In It Takes a Genome, Greg Gibson posits a revolutionary new hypothesis: Our genome is out of equilibrium, both with itself and its environment. Simply put, our genes aren't coping well with modern culture.

While we joke that men are from Mars and women are from Venus, our gender differences can't compare to those of other animals. For instance: the male garden spider spontaneously dies after mating with a female more than fifty times his size. Female cichlids must guard their eggs and larvae--even from the hungry appetites of their own partners. And male blanket octopuses employ a copulatory arm longer than their own bodies to mate with females that outweigh them by four orders of magnitude. Why do these gender gulfs exist?

When his missionary brother renounced faith in favor of atheism, Perry Marshall was plunged into crisis and doubt. He decided: “I”m going to let science make this decision for me.” He asked: “Is the hand at the end of my arm purposeful? Or is it purposeless?” He leapt into the void of evolution and the origin of life. He could not have begun to anticipate what he was about to discover. Living things were far more sophisticated than textbooks were saying.

James Dearsley’s wife thought he had lost his mind when he announced his intention to become a beekeeper. But like many interested in the self-sufficient lifestyle, he loved gardening and growing vegetables on his allotment and the old romantic in him had idealistic notions of teaching his little boy where honey came from, so he set himself what seemed a reasonable goal: to get, in a year’s time, just one jar of honey.

The Log from the Sea of Cortez is the exciting day-by-day account of Steinbeck's trip to the Gulf of California with biologist Ed Ricketts. Drawn from the longer Sea of Cortez, it is a wonderful combination of science, philosophy, and high-spirited adventure.

A list of the attributes that define a mammal is a ragbag of things - fur, live birth, three bones in the middle ear, a brain whose two halves are robustly joined together.... But this curious collection of features contain the roots of all the biology that makes us what we are: monkeys with massive brains who parent extensively, enjoy sport and think lots. Which is to say, what makes us mammals makes us human.

In this brilliant portrait of the oceans' unlikely hero, H. Bruce Franklin shows how menhaden have shaped America's national-and natural-history, and why reckless overfishing now threatens their place in both. Since Native Americans began using menhaden as fertilizer, this amazing fish has greased the wheels of U.S. agriculture and industry.

"Was macht denn den Menschen aus, aus Sicht der Neurobiologie heute - nicht nur gegenüber Außerirdischen, sondern auch in Abgrenzung tierischer Lebensformen..."

Feeling feverish, tired, or achy? Listening to Gina Kolata's engrossing account of the 1918 Influenza epidemic is sure to give you the chills. A gripping work of science writing, Flu addresses the prospects for a great epidemic recurring, and considers what can be done to prevent it.

All life as we know it is carbon-based and reliant on sources of liquid water and energy for its survival; it is also, of course, known from just one planet: the Earth, a world perfectly suited to host life. But across a universe of at least 100 billion habitable, earthlike worlds, life cannot be restricted to just this one place. Or can it?

As the snow melts and the spring approaches, the animal kingdom awakens. In Summer World, Bernd Heinrich, the best-selling author of Winter World, brings us an up-close and personal view of that awakening and rebirth.

Named one of the top books of 2009 by the Times Literary Supplement (London), this controversial and compelling audiobook from Dr. Stephen C. Meyer presents a convincing new case for intelligent design (ID) based on revolutionary discoveries in science and DNA. Along the way Meyer argues that Charles Darwin's theory of evolution as expounded in The Origin of Species did not, in fact, refute ID.

The most valuable investment any society makes is in its children, the next generation. The more we learn about the fetus the better we are able to understand the problems and abnormalities that can occur during development. Dr. Peter Nathanielsz, the first to demonstrate that the fetal brain delivers the signals that start the process of birth, reviews the recent explosion of information on fetal development during the second half of pregnancy.

Her name was Henrietta Lacks, but scientists know her as HeLa. She was a poor Southern tobacco farmer who worked the same land as her slave ancestors, yet her cells - taken without her knowledge - became one of the most important tools in medicine: The first “immortal” human cells grown in culture, which are still alive today, though she has been dead for more than 60 years. HeLa cells were vital for developing the polio vaccine; uncovered secrets of cancer, viruses, and the atom bomb’s effects.

Best-selling, award-winning author Laurie R. King’s tales featuring Sherlock Holmes and Mary Russell are among the most popular mysteries being published. Here, King explores the great detective’s initial meeting with Russell. Holmes is in a decidedly dark temper as he searches the countryside for wild bees, until he meets the headstrong young woman who will become his apprentice and eventual bride.

In Consilience (a word that originally meant "jumping together"), Edward O. Wilson renews the Enlightenment's search for a unified theory of knowledge in disciplines that range from physics to biology, the social sciences and the humanities. Using the natural sciences as his model, Wilson forges dramatic links between fields. Presenting the latest findings in prose of wonderful clarity and oratorical eloquence, and synthesizing it into a dazzling whole, Consilience is science in the path-clearing traditions of Newton, Einstein, and Richard Feynman.
