Book Description
Emlen takes us outside the lab and deep into the forests and jungles where he's been studying animal weapons in nature for years, to explain the processes behind the most intriguing and curious examples of extreme animal weapons. As singular and strange as some of the weapons we encounter on these pages are, we learn that similar factors set their evolution in motion. Emlen uses these patterns to draw parallels to the way we humans develop and employ our own weapons, and have since battle began.

Book Description
WINNER OF THE PHI BETA KAPPA AWARD IN SCIENCE The story behind the stunning, extreme weapons we see in the animal world--teeth and horns and claws--and what they can tell us about the way humans develop and use arms and other weapons In Animal Weapons, Doug Emlen takes us outside the lab and deep into the forests and jungles where he's been studying animal weapons in nature for years, to explain the processes behind the most intriguing and curious examples of extreme animal weapons—fish with mouths larger than their bodies and bugs whose heads are so packed with muscle they don't have room for eyes. As singular and strange as some of the weapons we encounter on these pages are, we learn that similar factors set their evolution in motion. Emlen uses these patterns to draw parallels to the way we humans develop and employ our own weapons, and have since battle began. He looks at everything from our armor and camouflage to the evolution of the rifle and the structures human populations have built across different regions and eras to protect their homes and communities. With stunning black and white drawings and gorgeous color illustrations of these concepts at work, Animal Weapons brings us the complete story of how weapons reach their most outsized, dramatic potential, and what the results we witness in the animal world can tell us about our own relationship with weapons of all kinds.

Book Description
"Fascinating.... Lays a foundation for understanding human history."—Bill Gates In this "artful, informative, and delightful" (William H. McNeill, New York Review of Books) book, Jared Diamond convincingly argues that geographical and environmental factors shaped the modern world. Societies that had had a head start in food production advanced beyond the hunter-gatherer stage, and then developed religion --as well as nasty germs and potent weapons of war --and adventured on sea and land to conquer and decimate preliterate cultures. A major advance in our understanding of human societies, Guns, Germs, and Steel chronicles the way that the modern world came to be and stunningly dismantles racially based theories of human history. Winner of the Pulitzer Prize, the Phi Beta Kappa Award in Science, the Rhone-Poulenc Prize, and the Commonwealth club of California's Gold Medal.

Book Description
Join scientist Doug Emlen on his quest to find out why an elusive type of beetle grows weapons that are enormous for its body size. What does it take to be a scientist in the field? Doug Emlen is a scientist. He studies beetles. Specifically, he studies the evolution of beetle weapons—how their horns and armor change to better suit them in different environments. This book starts with a mystery: Doug wanted to know why a particular type of beetle developed a massive evolutionary weapon. He wanted to know how these changes happened and what advantages these enormous weapons gave the tiny dung beetles. So, he went to visit. Part travel diary and part scientific exploration, Beetle Battles takes you deep into the South American rainforest to monitor beetles in their own habitat. Packed with color photographs, extensive back matter, and entertaining anecdotes, this book will make beetle fans out of all its young readers.
