From the primordial soup to meteorite impact zones, the Manhattan Project to the latest research, this book is the first full history of the scientists who strive to explain the genesis of life.

How did life begin? Why are we here? These are some of the most profound questions we can ask.
 
For almost a century, a small band of eccentric scientists has struggled to answer these questions and explain one of the greatest mysteries of all: how and why life began on Earth. There are many different proposals, and each idea has attracted passionate believers who promote it with an almost religious fervor, as well as detractors who reject it with equal passion.
 
But the quest to unravel life’s genesis is not just a story of big ideas. It is also a compelling human story, rich in personalities, conflicts, and surprising twists and turns. Along the way, the journey takes in some of the greatest discoveries in modern biology, from evolution and cells to DNA and life’s family tree. It is also a search whose end may finally be in sight.
 
In The Genesis Quest, Michael Marshall shows how the quest to understand life’s beginning is also a journey to discover the true nature of life, and by extension our place in the universe.

During the Middle Paleolithic, various populations ancestral to modern Homo sapiens inhabited Africa, while Europe was homeland to the Neandertals. Recent archaeological investigations have provided data showing that the abrupt transition from the Middle to the Upper Neolithic, during which these populations met and interacted, was a fast-moving period of change for both groups.

In this volume, the expansion of modern humans and their impact on the populations of Neandertals in Europe, Western Asia, and Northern Africa is discussed in depth, with particular focus on the lithic industries of the late Middle and early Upper Paleolithic.

What a big brain we have for all the small talk we make. It's an evolutionary riddle that at long last makes sense in this intriguing book about what gossip has done for our talkative species. Psychologist Robin Dunbar looks at gossip as an instrument of social order and cohesion--much like the endless grooming with which our primate cousins tend to their social relationships.

Apes and monkeys, humanity's closest kin, differ from other animals in the intensity of these relationships. All their grooming is not so much about hygiene as it is about cementing bonds, making friends, and influencing fellow primates. But for early humans, grooming as a way to social success posed a problem: given their large social groups of 150 or so, our earliest ancestors would have had to spend almost half their time grooming one another--an impossible burden. What Dunbar suggests--and his research, whether in the realm of primatology or in that of gossip, confirms--is that humans developed language to serve the same purpose, but far more efficiently. It seems there is nothing idle about chatter, which holds together a diverse, dynamic group--whether of hunter-gatherers, soldiers, or workmates.

Anthropologists have long assumed that language developed in relationships among males during activities such as hunting. Dunbar's original and extremely interesting studies suggest otherwise: that language in fact evolved in response to our need to keep up to date with friends and family. We needed conversation to stay in touch, and we still need it in ways that will not be satisfied by teleconferencing, email, or any other communication technology. As Dunbar shows, the impersonal world of cyberspace will not fulfill our primordial need for face-to-face contact.

From the nit-picking of chimpanzees to our chats at coffee break, from neuroscience to paleoanthropology, Grooming, Gossip, and the Evolution of Language offers a provocative view of what makes us human, what holds us together, and what sets us apart.
