How did the dog become man's best friend? A celebrated anthropologist unearths the mysterious origins of the unique partnership that rewrote the history of both species.
Dogs and humans have been inseparable for more than 40,000 years. The relationship has proved to be a pivotal development in our evolutionary history. The same is also true for our canine friends; our connection with them has had much to do with their essential nature and survival. How and why did humans and dogs find their futures together, and how have these close companions (literally) shaped each other? Award-winning anthropologist Pat Shipman finds answers in prehistory and the present day.
In Our Oldest Companions, Shipman untangles the genetic and archaeological evidence of the first dogs. She follows the trail of the wolf-dog, neither prehistoric wolf nor modern dog, whose bones offer tantalizing clues about the earliest stages of domestication. She considers the enigma of the dingo, not quite domesticated yet not entirely wild, who has lived intimately with humans for thousands of years while actively resisting control or training. Shipman tells how scientists are shedding new light on the origins of the unique relationship between our two species, revealing how deep bonds formed between humans and canines as our guardians, playmates, shepherds, and hunters.
Along the journey together, dogs have changed physically, behaviorally, and emotionally, as humans too have been transformed. Dogs' labor dramatically expanded the range of human capability, altering our diets and habitats and contributing to our very survival. Shipman proves that we cannot understand our own history as a species without recognizing the central role that dogs have played in it.
Approximately 200,000 years ago, as modern humans began to radiate out from their evolutionary birthplace in Africa, Neanderthals were already thriving in Europe—descendants of a much earlier migration of the African genus Homo. But when modern humans eventually made their way to Europe 45,000 years ago, Neanderthals suddenly vanished. Ever since the first Neanderthal bones were identified in 1856, scientists have been vexed by the question, why did modern humans survive while their evolutionary cousins went extinct?
The Invaders musters compelling evidence to show that the major factor in the Neanderthals' demise was direct competition with newly arriving humans. Drawing on insights from the field of invasion biology, Pat Shipman traces the devastating impact of a growing human population: reduction of Neanderthals' geographic range, isolation into small groups, and loss of genetic diversity.
But modern humans were not the only invaders who competed with Neanderthals for big game. Shipman reveals fascinating confirmation of humans' partnership with the first domesticated wolf-dogs soon after Neanderthals first began to disappear. This alliance between two predator species, she hypothesizes, made possible an unprecedented degree of success in hunting large Ice Age mammals—a distinct and ultimately decisive advantage for humans over Neanderthals at a time when climate change made both groups vulnerable.
