The invasion of land by ocean-dwelling plants and animals was one of the most revolutionary events in the evolution of life on Earth, yet the animal invasion almost failed—twice—because of the twin mass extinctions of the Late Devonian Epoch. Some 359 to 375 million years ago, these catastrophic events dealt our ancestors a blow that almost drove them back into the sea. If those extinctions had been just a bit more severe, spiders and insects—instead of vertebrates—might have become the ecologically dominant forms of animal life on land. This book examines the profound evolutionary consequences of the Late Devonian extinctions and the various theories proposed to explain their occurrence. Only one group of four-limbed vertebrates exists on Earth, while other tetrapod-like fishes are extinct. This gap is why the idea of "fish with feet" seems so peculiar to us, yet such animals were once a vital part of our world, and if the Devonian extinctions had not happened, members of these species, like the famous Acanthostega and Ichthyostega, might have continued to live in our rivers and lakes. Synthesizing decades of research and including a wealth of new discoveries, this accessible, comprehensive text explores the causes of the Devonian extinctions, the reasons vertebrates were so severely affected, and the potential evolution of the modern world if the extinctions had never taken place.

The story behind D-Day begins in 1939 when Nazi Germany, led by Adolf Hitler, attacked Poland and ignited World War Two. The following year, the Germans occupied France and Western Europe and launched a vicious air war against Britain. In 1941, they invaded the Soviet Union. Seemingly unstoppable, the Nazis now held virtually all of Europe. They imposed a ruthless system of control and unleashed the horror of the Holocaust. However, by 1943, the tide had begun to turn in favor of the Allies, the forces opposed to Germany. In the east, despite huge losses, the Soviets began to force the Germans back.
b”A COMPANION TO JOHN F. KENNEDYA COMPANION TO JOHN F. KENNEDY “Marc J. Selverstone has compiled an indispensable volume of essays on John F. Kennedy and his presidency, written by a stellar cast of scholars. What stands out in sharp relief in this wide-ranging and authoritative book is how consequential were Kennedy’s thousand days for the United States and for the world, and how controversial is his legacy. Fredrik Logevall, Stephen and Madeline Anbinder Professor of History, Cornell University “Marc J. Selverstone has brought together a remarkable group of scholars who illuminate the many important ideas of, and events that occurred during, this brief administration. This book is the best record of the Kennedy years.” Alan Brinkley, Allan Nevins Professor of American History, Columbia University “This collection of talented scholars and their research and thoughts on John F. Kennedy is an invaluable resource: a deeply informed conversation for the ages.’ Richard Reeves, writer, syndicated columnist, and senior lecturer at the Annenberg School for Communication at the University of Southern California
This “immaculately researched and compellingly written” WWII history sheds new light on Britain’s critical victory against Nazi invasion (The New Criterion). In the summer of 1940, the Nazi war machine was at its zenith. France, Denmark, Norway, and the Low Countries were all under occupation. Only Britain stood in the way of the complete triumph, and Hitler planned a two-pronged offensive?a blistering aerial bombardment followed by a land invasion?to subdue his final enemy. But for the first time in the war, Hitler did not prevail. As Leo McKinstry details in this fascinating new history, the British were far more ruthless and proficient than is usually recognized. The brilliance of the RAF in the Battle of Britain was not an exception but part of a pattern of magnificent organization that thwarted Hitler’s armies at every turn. Using a wealth of archival and primary source materials, Leo McKinstry provides a groundbreaking new assessment of the six fateful months in mid-1940 when Operation Sea Lion was all that stood between the Nazis and total victory.
