When The Invasion Of Land Failed

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 might have become the ecologically dominant forms of animal life on land. This book examines the profound evolutionary consequences of the Late Devonian extinctions, which shaped the composition of the modern terrestrial ecosystem. Only one group of four-limbed vertebrates now live on Earth while other tetrapod-like fishes are extinct. This gap is why the idea of “fish with feet” seems so peculiar yet these animals were once a vital part of our world.

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.

Since the early twentieth century, historians have traditionally defined manifest destiny as the belief that the United States was destined to expand from coast to coast. This generation of historians has posed manifest destiny as a unifying ideology of the nineteenth century, one that was popular and pervasive and ultimately fulfilled in the late 1840s when the United States acquired the Pacific Coast. However, the story of manifest destiny was never quite that simple. In A Failed Vision of Empire Daniel J. Burge examines the belief in manifest destiny over the nineteenth century by analyzing contested moments in the continental expansion of the United States, arguing that the ideology was ultimately unsuccessful. By examining speeches, plays, letters, diaries, newspapers, and other sources, Burge reveals how Americans debated the wisdom of expansion, challenged expansionists, and disagreed over what the boundaries of the United States should look like. A Failed Vision of Empire is the first work to capture the messy, complicated, and yet far more compelling story of manifest destiny’s failure, debunking in the process one of the most pervasive myths of modern American history.
