From shrews to blue whales, placental mammals are among the most diverse and successful vertebrates on the Earth. Arising sometime near the Late Cretaceous, this broad clade of mammals contains more than 1,000 genera and approximately 4,400 extant species. Although much studied, the origin and diversification of the placentals continue to be a source of debate.
Paleontologists Kenneth D. Rose and J. David Archibald have assembled the world's leading authorities to provide a comprehensive and up-to-date evolutionary history of placental mammals. Focusing on anatomical evidence, the...

In 1933 Americans did something they had never done before: they voted to repeal an amendment to the U.S. Constitution. The Eighteenth Amendment, which for 13 years had prohibited the manufacture and sale of alcoholic beverages, was nullified by the passage of another amendment, the Twenty-First. Many factors helped create this remarkable turn of events. One factor that was essential, Kenneth D. Rose here argues, was the presence of a large number of well-organized women promoting repeal.
Even more remarkable than the appearance of these women on the political scene was the approach...

For the half-century duration of the Cold War, the fallout shelter was a curiously American preoccupation. Triggered in 1961 by a hawkish speech by John F. Kennedy, the fallout shelter controversy---to dig or not to dig, - as Business Week put it at the time--forced many Americans to grapple with deeply disturbing dilemmas that went to the very heart of their self-image about what it meant to be an American, an upstanding citizen, and a moral human being.
Given the much-touted nuclear threat throughout the 1960s and the fact that 4 out of 5 Americans expressed a preference...

The late nineteenth century was a golden age for European travel in the United States. For prosperous Europeans, a journey to America was a fresh alternative to the more familiar 'Grand Tour' of their own continent, promising encounters with a vast, wild landscape, and with people whose culture was similar enough to their own to be intelligible, yet different enough to be interesting. Their observations of America and its inhabitants provide a striking lens on this era of American history, and a fascinating glimpse into how the people of the past perceived one another.
