Social Science Genetics

The Big Ratchet is the story of the ratchets: the technologies and innovations, big and small, that propelled our species from hunters and gatherers on the savannahs of Africa to shoppers in the aisles of the supermarket. Our species long lived on the edge of starvation. Now we produce enough food for all 7 billion of us to eat nearly 3,000 calories every day. This is such an astonishing thing in the history of life as to verge on the miraculous. The Big Ratchet is the story of how it happened.

For all that science knows about the living world, notes David P. Barash, there are even more things we don't know, genuine evolutionary mysteries that perplex the best minds in biology. Paradoxically, many of these mysteries are very close to home, involving some of the most personal aspects of being human. Homo Mysterious examines a number of these evolutionary mysteries, exploring things we don't yet know about ourselves, laying out the best current hypotheses, and pointing toward insights that scientists are just beginning to glimpse.

How did humans, a species of self-centered apes, come to care about others? Since Darwin, scientists have tried to answer this question using evolutionary theory. In The Kindness of Strangers, psychologist Michael E. McCullough shows why they have failed and offers a new explanation instead. From the moment nomadic humans first settled down until the aftermath of the Second World War, our species has confronted repeated crises that we could only survive by changing our behavior.

A powerful treatise that demonstrates the existence of altruism in nature, with surprising implications for human society. Does altruism exist? Or is human nature entirely selfish? In this eloquent and accessible book, famed biologist David Sloan Wilson provides new answers to this age-old question based on the latest developments in evolutionary science.

Over the past 100 years, gulls have been brought ashore by modernity. They now live not only on the coasts, but in our slipstream following trawlers, barges, and garbage trucks. They are more our contemporaries than most birds, living their wild lives among us in towns and cities. In many ways, they live as we do, walking the built-up world and grabbing a bite where they can. Yet this disturbs us. We’ve started fearing gulls for getting good at being among us. We see them as scavengers, not entrepreneurs; oceangoing aliens, not refugees.

Una storia prima della storia. Ossa fossili, denti, manufatti, siti preistorici e dati genetici per ricostruire l'evoluzione di un gruppo di scimmie antropomorfe che, intorno a 6 milioni di anni fa, in Africa, intrapresero l'intricato percorso evolutivo che diede origine alla nostra specie.

What can fossilized teeth tell us about our ancient life expectancy? What can big data on fossils reveal about farming's problematic role in human evolution? How can simple geometric comparisons of skull and pelvic fossils suggest an origin to our social nature? In Close Encounters with Humankind, paleoanthropologist Sang-Hee Lee explores some of our biggest evolutionary questions from unexpected new angles. Through a series of entertaining, bite-sized chapters, we gain new perspectives into our first hominin ancestors, our first steps on two feet, and more.

When did the human species turn against the planet that we depend on for survival? Human industry and consumption of resources have altered the climate, polluted the water and soil, destroyed ecosystems, and rendered many species extinct, vastly increasing the likelihood of an ecological catastrophe. How did humankind come to rule nature to such an extent? To regard the planet's resources and creatures as ours for the taking? To find ourselves on a seemingly relentless path toward ecocide?

The latest and most bitterly contested battle in the culture war is the controversy over Darwin and intelligent design. But much of what you've heard about it is wrong. Jonathan Wells, a battle-hardened veteran with doctorates in biology and theology, sets the record straight.

Already technology enables parents to select some genetic traits for their children, and soon it will be possible to begin to shape ourselves as a species. Countering loud cries of alarm, bioethics expert Ronald Green explains why our fears about genetic engineering are overblown and how we can move forward responsibly to create a better future.

As you read these words, planet Earth teems with trillions of life-forms, all going about their own business: eating, reproducing, thriving.... Yet the life of almost every single organism draws nearer to certain death. On the other hand, "suicide" inside the mitochondria that live within us results in the death of millions of cells each second for our own good! Why is death such a universal companion to life on Earth? Why haven't animals evolved to break free of its shackles?

In 1955, on a visit to South Africa, Robert Ardrey became aware of the growing evidence that man had evolved on the African continent from carnivorous, predatory stock - ones who had also, long before man, achieved the use of weapons. A dramatist, Ardrey's interest in the African discoveries sprang less from purely scientific grounds than from the radical new light they cast on the eternal question: Why do we behave as we do? Are we naturally inclined towards war and weapons?

The cells in our bodies consist of molecules, made up of the same carbon, oxygen, and hydrogen atoms found in air and rocks. But molecules, such as water and sugar, are not alive. So how do our cells - assemblies of otherwise "dead" molecules - come to life, and together constitute a living being? In Life’s Ratchet, physicist Peter M. Hoffmann locates the answer to this age-old question at the nanoscale.

In Berinin, a new Chieftain Heir is born, but only his grandfather and a child from ArcNos know the truth of his birth. In Ferya, a denial of paternity fractures a family. In Ivaria, the plight of an orphan motivates his adoptive father to seek a child of his own blood. These four children - MeiLom of ArcNos, Galo of Berinin, Eytea of Ferya, and Vielle of Ivaria - are part of a long-forgotten line of hominids called Hybrids.

Scientists' understanding of life is progressing more rapidly than at any point in human history, from the extraordinary decoding of DNA to the controversial emergence of biotechnology. Featuring pioneering biologists, geneticists, physicists, and science writers, Life explains just how far we've come - and takes a brilliantly educated guess at where we're heading.

With the ongoing advancement of AI and other technologies, our world is becoming increasingly intelligent. From chatbots to innovations in brain-computer interfaces to the possibility of superintelligences leading to the Singularity later this century, our reality is being transformed before our eyes. This is commonly seen as the natural result of progress, but what if there's more to it than that? What if intelligence is an inevitability, an underlying property of the universe?

Half a decade has passed since the ArcNosian Civil War. Nations have been rebuilt. Peace has been restored. And the Avatars of Fate have been deathly silent. No sooner are Sinkua and Eytea called back to ArcNos than the gears begin turning again. Money begins vanishing from ArcNos. Scandals threaten the new power structure. Sinkua ends up at the center of a debacle that threatens Galo's sovereignty. Old allies and new faces emerge as an anti-Avatar force called the Coalition. They've worked in secret for decades, but the time has come for their disclosure.

Survival of the fittest or survival of the nicest? Since the dawn of time man has contemplated the mystery of altruism, but it was Darwin who posed the question most starkly. From the selfless ant to the stinging bee to the man laying down his life for a stranger, evolution has yielded a goodness that in theory should never be. Set against the sweeping tale of 150 years of scientific attempts to explain kindness, The Price of Altruism tells for the first time the moving story of the eccentric American genius George Price (1922-1975), as he strives to answer evolution's greatest riddle.

Unnatural Selection is the first book to examine the rise of the "technocentric being" - or geek - who personifies a distinct new phase in human evolution. People considered geeks often have behavioral or genetic traits that were previously considered detrimental. But the new environment of the Anthropocene period - the Age of Man - has created a kind of digital greenhouse that actually favors their traits, enabling many non-neurotypical people to bloom.

This dynamic chronicle of the race to find the "missing links" between humans and apes transports readers into the highly competitive world of fossil hunting and into the lives of the ambitious scientists intent on pinpointing the dawn of humankind. The quest to find where and when the earliest human ancestors first appeared is one of the most exciting and challenging of all scientific pursuits.
