The Roman empire tends to be seen as a whole whereas the early middle ages tends to be seen as a collection of regional histories, roughly corresponding to the land-areas of modern nation states. As a result, early medieval history is much more fragmented, and there have been few convincing syntheses of socio-economic change in the post-Roman world since the 1930s. In recent decades, the rise of early medieval archaeology has also transformed our source-base, but this has not been adequately integrated into analyses of documentary history in almost any country. In Framing the Early Middle Ages Chris Wickham aims at integrating documentary and archaeological evidence together, and also, above all, at creating a comparative history of the period 400-800, by means of systematic comparative analyses of each of the regions of the latest Roman and immediately post-Roman world, from Denmark to Egypt (only the Slav areas are left out).
What if one of Napoleon's most trusted commanders had spiked Wellington's guns with a handful of nails at Waterloo in 1815, handing victory to his Emperor? What if Hitler hadn't paused for three vital days in his invasion of France in May 1940, allowing the British Expeditionary Force precious time to evacuate from Dunkirk? It is moments like these, argues Erik Durschmied, that provide The Hinge Factor in history: moments of stupidity, chance or accident which have irrevocably changed the outcome of human history, for better or for worse.

Researching your family history can be an absorbing hobby, or a one-off project that your whole family will value and build on. You can do it seriously or just for fun and a conversation topic, especially at family gatherings. This book will lead you to the vast number of genealogy websites, where family history research that used to take months can now produce exciting results in a weekend. Or you can find out how to do your own detective work at friendly record offices and beautiful parish church cemeteries.
Biology is often viewed today as a bipartisan field, with molecular level genetics guiding us into the future and natural history (including ecology, evolution, and conservation biology,) chaining us to a descriptive scientific past. In Darwinian Detectives, Norman Johnson bridges this divide, revealing how the tried and true tools of natural history make sense of the newest genomic discoveries. Molecular scientists exploring newly sequenced genomes have stumbled upon quite a few surprises, including that only one to ten percent of the genetic material of animals actually codes for genes. What does the remaining 90-99% of the genome do? Why do some organisms have a much lower genome size than their close relatives? What were the genetic changes that were associated with us becoming human? As molecular biologists uncover these and other new mysteries, evolutionary geneticists are searching for answers to such questions. Norman Johnson captures the excitement of the hunt for our own genetic history. Through lively anecdotes, he explores how researchers detect natural selection acting on genes and what this genetic information tells us about human origins.
