The idea of migration in prehistory, so long out of favor, is back on the agenda. New advances allow us to track human movement and the spread of crops, animals, and disease, and we can see the evidence of population crashes and rises, both continent-wide and locally. Visions of continuity have been replaced with a more dynamic view of Europe’s past, with one wave of migration followed by another, from the first human arrivals in Europe to the Vikings.Ancient DNA links Europe to its nearest neighbors. It is not a new idea that farming was brought from the Near East, but genetics now reveal an unexpectedly complex process in which farmers arrived not in one wave, but several. Even more unexpected is the evidence that the European gene pool was stirred vigorously many times after farming had reached most of Europe. Climate change played a part in this upheaval, but so did new inventions such as the c and wheeled vehicles. Genetic and linguistic clues also enhance our understanding of the upheavals of the Migration Period, the wanderings of steppe nomads, and the adventures of the Vikings.

    Mumford has drawn on every aspect of life to explain the machine and to trace its social results. "An extraordinarily wide-ranging, sensitive, and provocative book about a subject upon whichphilosophers have so far shed but little light" (Journal of Philosophy).

    Christopher Ryan and Cacilda Jethá claim that their evidence shows that before 10,000 years ago sexual constraints did not exist, paternity was not an issue, and men and women engaged in fairly free and casual bonobo-like sexual activity. Our ancestors, they argue, not only shared food, they shared sex. Are they right? Using predominantly the same sources, SEX AT DUSK takes another look at that evidence, fills in many gaps, makes many corrections, and reveals something far less candy-coated. Bringing together evolutionary biology, primatology, anthropology, and human sexuality, SEX AT DUSK shows that, rather than revealing important facts about our sexual evolution, Ryan and Jethá shroud it in a fog of misinformation and faulty logic that can only lead us further into the dark."Nearly all biologists, including yours truly, haven’t bothered to waste their time on such tripe [Sex at Dawn], although a case can be made that we have a professional responsibility to respond when the public is being so egregiously misled. Fortunately, a rebuttal to the Sex at Dawn nonsense is now available via Amazon: Sex at Dusk. It’s not only a suitable slap-down of its woeful predecessor, but Ms. Saxon even got the science right! Moreover, she has a wide-ranging and delightful mind, worth spending time with." David Barash, author of The Myth of Monogamy: fidelity and infidelity in animals and people (Holt, 2002)"Human sexuality has always been politicized, prettified, sanitized, romanticized and mythologized. For adults for whom truth is the ultimate turn-on, I recommend Lynn Saxon's insightful treatment of this eternally fascinating subject." Steven Pinker, Harvard College Professor of Psychology, Harvard University, and the author of How the Mind Works and The Blank Slate."Cleaning the Augean Stables was one of Hercules's more odious tasks, but also perhaps the most useful. Correcting the errors and misrepresentations of Sex at Dawn has been Lynn Saxon's self-imposed labor, and she does it with Herculean strength. Moreover, Sex at Dusk isn't only well-written and scientifically valid, it is great fun as well! This particular transition from Dawn to Dusk is not only natural, but much needed." David P. Barash, Professor of Psychology, University of Washington, Seattle and author of Homo mysterious: evolutionary puzzles of human nature." (Oxford University Press)

    He untangles the pattern of interconnecting events, the accidents of time, circumstance, and place that gave rise to major inventions of the world. Says Burke, "My purpose is to acquaint the reader with some of the forces that have caused change in the past, looking in particular at eight innovations - the computer, the production line, telecommunications, the airplane, the atomic bomb, plastics, the guided rocket, and television - which may be most influential in structuring our own futures.... Each one of these is part of a family of similar devices, and is the result of a sequence of closely connected events extending from the ancient world until the present day. Each has enormous potential for humankind's benefit - or destruction."
