How animals big and small have shaped today's world. From furry felines to hard-working horses, animals have had a tremendous impact on world history. For example, rats, through the diseases they carry, have probably killed more people than any war or natural disaster, goats may have been the first to discover coffee and, thanks to camels, people were able to survive for long periods in the desert and open up trade routes between Europe and Asia. However, animals can also be destructive. Mosquitoes spread deadly diseases -- and may even have killed Alexander the Great. Some animals have changed the environment by damaging whole ecosystems, creating deserts in their wake. Others, like the elephant, have been used as weapons of war. Among the more than 20 animals featured in this book are dogs, sheep, dolphins, silk moths and beavers, all of which have changed the course of history for better or for worse.
