study of the pre-Columbian Americas -- a deeply engaging new history of the most momentous biological event since the death of the dinosaurs. More than 200 million years ago, geological forces split apart the continents. Isolated from each other, the two halves of the world developed radically different suites of plants and animals. When Christopher Columbus set foot in the Americas, he ended that separation at a stroke. Driven by the economic goal of establishing trade with China, he accidentally set off an ecological convulsion as European vessels carried thousands of species to new homes across the oceans. The Columbian Exchange, as researchers call it, is the reason there are tomatoes in Italy, oranges in Florida, chocolates in Switzerland, and chili peppers in Thailand. More important, creatures the colonists knew nothing about hitched along for the ride. Earthworms, mosquitoes, and cockroaches; honeybees, dandelions, and African grasses; bacteria, fungi, and viruses; rats of every description -- all of them rushed like eager tourists into lands that had never seen their like before, changing lives and landscapes across the planet. Eight decades after Columbus, a Spaniard named Legazpi succeeded where Columbus had failed. He sailed west to establish continual trade with China, then the richest, most powerful country in the world.

Many folks are probably familiar with what happened in Europe post-1492, but there's a whole bunch of stuff on the Pacific side of the Americas as well.
Charles Mann wrote a great book, 1493, on the Colombian Exchange which I'd highly recommend. The introduction of malaria to the Americas is one underappreciated aspect of that he introduced me to.
I'll never take any 'historical fact' for granted again.
A reference to 1492, the year that Columbus landed in the Western Hemisphere, this book is all about the Columbian Exchange. The effects of plant, animal, and microbial species suddenly flowing all throughout a world that until that moment had quite separate and isolated biospheres.
