In this fresh and provocative view of a seven-million-year evolutionary journey, Finlayson demonstrates the radical implications for the interpretation of fossils and technologies and shows that understanding humans within an ecological context provides insights into the emergence and spread of Homo sapiens worldwide.

Since moving west over a decade ago, Tom Groneberg has worked with horses as a trail guide, as a ranch hand, and as the manager of his own ranch in Montana, but he has never owned a really good horse. Until, on an autumn night, in a warm barn under a blanket of snow, Blue is born. Soon, he will belong to Tom Groneberg. "If I had a good horse," writes Tom, "I could give it my life. I could ride it for years. We could grow old together." So begins this unique American love story about a man and his horse.

As a young boy, the author took part in collecting specimens for his father. Fifty years later, he was asked to join a team from the same institution studying the state of sea life in the Bahamian waters where he grew up, as measured against his father’s benchmark. The first of the sea changes presented in this eloquent book stems from climate change and is the drastic transformation of ocean life due to global warming - but there are more.

In How We Do It, primatologist Robert Martin draws on 40 years of research to locate the roots of everything from our sex cells to the way we care for newborns. He examines the procreative history of humans as well as that of our primate kin to reveal what's really natural when it comes to making and raising babies, and distinguish which behaviors we ought to continue - and which we should not. Although it's not realistic to raise our children like our ancestors did, Martin’s investigation reveals surprising consequences of - and suggests ways to improve upon - the way we do things now.

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 the summer of 2004, veterinarian Melanie Butera received an unexpected patient: a three-day-old blind, dying fawn she called Dillie. Melanie doubted the deer would survive, but with the help of her husband, Steve, she miraculously nursed Dillie back to health. The tenacious deer quickly became a member of the family, running around the house with the dog, the cat, and the people and enjoying all of the perks, including her own bedroom, plates of her favorite linguini, and swims in the family's pool.

Most of the 25,000 genes we possess are the same for all of us. Compatibility genes are those that vary most from person to person and give each of us a unique molecular signature. These genes determine both the extent to which we are susceptible to a vast range of illnesses and the different ways each of us fights disease.

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.

Hundreds of thousands of people die every year from malaria. No one's quite sure of the exact number. It's just too difficult to keep track of the disease as it tears through more than 200 million cases each year, many of them in countries wracked by war and blighted by other problems. In The Deadly Air, Christian Jennings mixes together his own experiences of suffering from malaria with a history of mankind's struggle with the disease.

From roots to canopy, a lush, verdant history of the making of California. California now has more trees than at any time since the late Pleistocene. This green landscape, however, is not the work of nature. It’s the work of history. In the years after the Gold Rush, American settlers remade the California landscape, harnessing nature to their vision of the good life. Horticulturists, boosters, and civic reformers began to "improve" the bare, brown countryside, planting millions of trees to create groves, wooded suburbs, and landscaped cities.

Patagonia. The name connotes the exotic and a distance that seems nearly mythical. Tucked toward the toe of South America, this largely unsettled landscape is among the most varied and breathtaking in the world - aching in its beauty as it sweeps from the Andes through broad, arid steppes to pristine beaches and down to a famously violent sea. It is also home to a vast array of rare wildlife as diverse and fascinating as the region itself.

A moving collection of fishing stories by one of America’s legendary outdoor writers. Throughout his career, Harry Middleton contributed hundreds of stories, essays, and book reviews to some of the most respected periodicals, including the New York Times, Sports Illustrated, Gray’s Sporting Journal, Field & Stream, Country Journal, Smithsonian, and Sierra, among others.

Picking up where she left off in Where the Blind Horse Sings, Kathy Stevens regales us with more tales of the rescued animals at Catskill Animal Sanctuary (CAS), some touching, some hilarious, all provocative. We meet Barbie, the broiler hen found hiding under a blue Honda in Brooklyn who falls for the animal ambassador Rambo, a ram with an uncanny sense of what others need. Then there’s Norma Rae, the turkey rescued from a "turkey bowl" just before Thanksgiving.

In the aftermath of the horrific trench warfare of the First World War, the poppy - sprouting across the killing fields of France and Belgium, then immortalized in John McCrae’s moving poem - became a worldwide icon. Yet the poppy has a longer history: as the telltale sign of human cultivation of the land, of the ravages of war, and of the desire to escape the earthly realm through Romantic opium dreams or the grim reality of morphine drips.

From the family to the workplace to the marketplace, every facet of our lives is shaped by cooperative interactions. Yet everywhere we look, we are confronted by proof of how difficult cooperation can be - snarled traffic, polarized politics, overexploited resources, social problems that go ignored. The benefits to oneself of a free ride on the efforts of others mean that collective goals often are not met. But compared to most other species, people actually cooperate a great deal. Why is this?

Draghi, ciclopi, giganti, unicorni, fenici. Quando gli antichi si imbattevano in resti di animali sconosciuti, subito li attribuivano a creature fantastiche. Poi gli scienziati hanno dimostrato che si trattava solo di fantasie ancestrali: i mostri non esistono, oggi lo sappiamo tutti; eppure la spiegazione che gli studiosi hanno dato di quei reperti è stata addirittura più terrificante: prima di noi, una miriade di altri viventi abitava il nostro pianeta, ma ora non ci sono più. Sulla Terra, infatti, nulla è per sempre.

Come limitare l'impatto dei consumi di energia sull'uomo e sull'ambiente, senza compromettere lo sviluppo economico? Un impiego delle fonti rinnovabili, e in particolare dell'energia solare, è ormai ritenuto necessario e possibile, anche in ampie proporzioni. Nel volume si discutono gli aspetti tecnologici ed economici dello sfruttamento dell'energia solare e si offre un quadro delle politiche nazionali e dell'Unione europea nel settore.

Siamo nel 2083. Anna ha 110 anni, è ancora in gamba, ma inciampa in un tappeto e cade rompendosi il femore; resta distesa ad aspettare e nel giro di una decina di minuti potrà rialzarsi in piedi poiché il femore si è auto-riparato. Come è potuto accadere? Dall'anno 2070 gli ultracentenari assumono nano-particelle autoadesive che vanno a rimpiazzare una parte dei costituenti delle ossa.

Mummie del ghiaccio, delle cripte e delle catacombe, arrivate fino a noi dalle Ande alla Cina. I diversi processi di mummificazione, a cui sono stati sottoposti - per citare tre casi famosi - Ötzi, Tutankhamon, Evita Perón, ci permettono di affondare lo sguardo nelle condizioni di vita degli uomini del passato. Grazie ai metodi più avanzati della bioarcheologia molecolare, inoltre, si può far luce sulle patologie antiche e trarne informazioni importanti sull'evoluzione di alcune malattie del nostro tempo.

Sebbene esista la convinzione che parlare alle piante ne favorisca la crescita, sembra tuttavia alquanto strano immaginare che le piante abbiano una vita mentale. Se però consideriamo che pensare non è altro che la capacità di recepire stimoli dall'ambiente, elaborarli e mettere in atto strategie per sopravvivere, allora possiamo ritenere che le piante abbiano una qualche forma di pensiero e intelligenza. L'autore ci introduce nel mondo delle piante e ne svela i segreti.
