Without domestication, civilization as we know it would not exist.
Since that fateful day when the first wolf decided to stay close to human hunters, humans and their various animal companions have thrived far beyond nearly all wild species on earth. Tameness is the key trait in the domestication of cats, dogs, horses, cows, and other mammals, from rats to reindeer. Surprisingly, with selection for tameness comes a suite of seemingly unrelated alterations, including floppy ears, skeletal and coloration changes, and sex differences. It’s a package deal known as the domestication syndrome, elements of which are also found in humans. Our highly social nature—one of the keys to our evolutionary success—is due to our own tameness. In Domesticated, Richard C. Francis weaves history and anthropology with cutting-edge ideas in genomics and evo devo to tell the story of how we domesticated the world, and ourselves in the process.
PUBLISHERS WEEKLY
With encyclopedic detail, Francis (Epigenetics) investigates the nature of domestication, focusing mostly on the biological rather than anthropological factors responsible for a wide array of human/animal partnerships. He ranges widely across species, including house pets, livestock, and pack animals, discussing the types of genetic changes that commonly occur during the process of domestication and the developmental implications such changes have. Francis describes how tameness, tolerance of human contact, and increased in-group sociality are frequent precursors to domestication and are often allied with the retention of juvenile traits in adults. Offering an effective primer on molecular genetics and the field of evolutionary development, he also demonstrates how conservative evolution can be, even while documenting some of the amazing changes species have undergone in relatively short periods of time due to strong selection imposed by humans. In his exploration of human evolution, he asks whether our species has experienced, via "self-domestication," some of the same physical and cultural changes as have our domesticated companions; he concludes that the available data are not yet robust enough to form a firm conclusion about the self-domestication hypothesis, but suggests that our success as a species could be largely due to our enhanced sociality. Though the details can be overwhelming, Francis's ability to weave in interesting asides keeps the text thought provoking. Illus.
