Most claims of Native American ancestry rest on the mother's ethnicity. This can be verified by a DNA test determining what type of mitochondrial DNA she passed to you. A hundred participants in DNA Consultants multi-phase Cherokee DNA Study did just that. What they had in common is they were previously rejected - by commercial firms, genealogy groups, government agencies and tribes. Their mitochondrial DNA was not classified as Native American. These are the "anomalous" Cherokee.

Life on earth is facing unprecedented challenges from global warming, war, and mass extinctions. The plight of seeds is a less visible but no less fundamental threat to our survival. Seeds are at the heart of the planet's life-support systems. Their power to regenerate and adapt are essential to maintaining our food supply and our ability to cope with a changing climate. Environmental journalist Claire Hope Cummings exposes the stories behind the rise of industrial agriculture and plant biotechnology, the fall of public interest science, and the folly of patenting seeds.

Why are we the way we are? Why do some of us find it impossible to calm a quick temper or to shake anxiety? The debate has always been divided between nature and nurture, but as psychology professor Daniel P. Keating demonstrates in Born Anxious, new DNA science points to a third factor that allows us to inherit both the nature and the nurture of previous generations - with significant consequences.

In Star Trek, crew members travel to unusual planets, meet diverse beings, and encounter unique civilizations. Throughout these remarkable space adventures, does Star Trek reflect biology and evolution as we know it? What can the science in the science fiction of Star Trek teach us? In Live Long and Evolve, biologist and die-hard Trekkie Mohamed Noor takes fans on a fun, fact-filled scientific journey. Noor offers Trekkies, science-fiction fans, and anyone curious about how life works a cosmic gateway into introductory biology.

From the Siberian permafrost to balmy California, scientists across the globe are working to resurrect all kinds of extinct animals, from ones that just left us to those that have been gone for many thousands of years. Their tools in this hunt are both fossils and cutting-edge genetic technologies. Some of these scientists are driven by sheer curiosity; others view the lost species as a powerful weapon in the fight to preserve rapidly changing ecosystems. It seems certain that these animals will walk the earth again, but what world will that give us? And is any of this a good idea?

What makes you the way you are - and what makes each of us different from everyone else? In Innate, leading neuroscientist and popular science blogger Kevin Mitchell traces human diversity and individual differences to their deepest level: in the wiring of our brains.

Two Nobel Laureates discuss the genome and more. James D. Watson changed the course of history with his discovery of DNA, the "secret of life". Watson is the recipient of the Presidential Medal of Freedom, the National Medal of Science, and, with Francis Crick and Maurice Wilkins, the 1962 Nobel Prize in Physiology or Medicine.

Since the birth of civilization, human beings have manipulated other life-forms. We have selectively bred plants and animals for thousands of years to maximize agricultural production and cater to our tastes in pets. The observation of the creation of artificial animal and plant variants was a key stimulant for Charles Darwin's theory of evolution. The ability to directly engineer the genomes of organisms first became possible in the 1970s, when the gene for human insulin was introduced into bacteria.

Could extinct species, like mammoths and passenger pigeons, be brought back to life? The science says yes. In How to Clone a Mammoth, Beth Shapiro, evolutionary biologist and pioneer in "ancient DNA" research, walks listeners through the astonishing and controversial process of de-extinction.

A panoramic overview of biotechnologies that can endlessly boost human capabilities and the drastic changes these "superhuman" traits could trigger. Biotechnology is moving fast. In the coming decades, advanced pharmaceuticals, bioelectronics, and genetic interventions will be used not only to heal the sick but to boost human physical and mental performance to unprecedented levels.

Most people know that Gregor Mendel, the Moravian monk who patiently grew his peas in a monastery garden, shaped our understanding of inheritance. But people might not know that Mendel's work was ignored in his own lifetime, even though it contained answers to the most pressing questions raised by Charles Darwin's revolutionary book, On Origrin of the Species, published only a few years earlier. Mendel's single chance of recognition failed utterly, and he died a lonely and disappointed man.

John Tyler Bonner, one of our most distinguished and insightful biologists, here challenges a central tenet of evolutionary biology. In this concise, elegantly written book, he makes the bold and provocative claim that some biological diversity may be explained by something other than natural selection. With his customary wit and accessible style, Bonner makes an argument for the underappreciated role that randomness - or chance - plays in evolution.

Despite extensive evidence highlighting the influence of genetics in the business world, this critical connection has been glossed over by corporate leaders and management gurus. Now, for the first time, author Scott Shane explains why genes matter, and how an understanding of their relationship to behavior is of vital importance to employers, employees, and policy makers.

If we are, in part, a product of our genes, can free will exist? Incisive and engaging, this indispensable tour of evolutionary biology runs the gamut of contemporary debates, from science and religion to our place in the universe.

In Food, Genes, and Culture, renowned ethnobotanist Gary Nabhan shows why the perfect diet for one person could be disastrous for another. If your ancestors were herders in Northern Europe, milk might well provide you with important nutrients, whereas if you’re Native American, you have a higher likelihood of lactose intolerance. If your roots lie in the Greek islands, the acclaimed Mediterranean diet might save your heart; if not, all that olive oil could just give you stomach cramps.

A vibrant young Hispano woman, Shonnie Medina, inherits a breast-cancer mutation known as BRCA1.185delAG. It is a genetic variant characteristic of Jews. The Medinas knew they were descended from Native Americans and Spanish Catholics, but they did not know that they had Jewish ancestry as well. The mutation most likely sprang from Sephardic Jews hounded by the Spanish Inquisition. The discovery of the gene leads to a fascinating investigation of cultural history and modern genetics by Dr. Harry Ostrer and other experts on the DNA of Jewish populations.

In Strange Bedfellows, David P. Barash and Judith Eve Lipton look at how biology actually promotes monogamy in some species and how these lessons apply to human beings. An accessible work of science that is relevant to our intimate daily life, Strange Bedfellows will reassure some people, surprise others, and engage everyone.
