Buried there lie answers about the origins of humankind. After a century of investigation, scientists have transformed our understanding about the beginnings of human life. But vital clues still remain hidden. In Born in Africa, Martin Meredith follows the trail of discoveries about human origins made by scientists over the last hundred years, recounting their intense rivalry, personal feuds, and fierce controversies as well as their feats of skill and endurance.The results have been momentous. Scientists have identified more than twenty species of extinct humans. They have firmly established Africa as the birthplace not only of humankind but also of modern humans. They have revealed how early technology, language ability, and artistic endeavour all originated in Africa; and they have shown how small groups of Africans spread out from Africa in an exodus sixty thousand years ago to populate the rest of the world. We have all inherited an African past.

    But for most of human history, practically no one slept this way. Tracing sleep's transformation since the dawn of the industrial age, Reiss weaves together insights from literature, social and medical history, and cutting-edge science to show how and why we have tried and failed to tame sleep. In lyrical prose, he leads readers from bedrooms and laboratories to factories and battlefields to Henry David Thoreau's famous cabin at Walden Pond, telling the stories of troubled sleepers, hibernating peasants, sleepwalking preachers, cave-dwelling sleep researchers, slaves who led nighttime uprisings, rebellious workers, spectacularly frazzled parents, and utopian dreamers. We are hardly the first people, Reiss makes clear, to chafe against our modern rules for sleeping.A stirring testament to sleep's diversity, Wild Nights offers a profound reminder that in the vulnerability of slumber we can find our shared humanity. By peeling back the covers of history, Reiss recaptures sleep's mystery and grandeur and offers hope to weary readers: as sleep was transformed once before, so too can it change today.

    Dennett, whom Chet Raymo of The Boston Globe calls "one of the most provocative thinkers on the planet," focuses his unerringly logical mind on the theory of natural selection, showing how Darwin's great idea transforms and illuminates our traditional view of humanity's place in the universe. Dennett vividly describes the theory itself and then extends Darwin's vision with impeccable arguments to their often surprising conclusions, challenging the views of some of the most famous scientists of our day.
