Once a Wolf: The Science Behind Our Dogs' Astonishing Genetic Evolution

by Bryan Sykes

Overview

The author of Seven Daughters of Eve returns with a lively account of how all dogs are descended from a mere handful of wolves.

How did wolves evolve into dogs? When did this happen, and what role did humans play? Oxford geneticist Bryan Sykes used the full array of modern technology to explore the canine genetic journey that likely began when a human child decided to adopt a wolf cub thousands of years ago. In the process, he discovered that only a handful of genes have created the huge range of shapes, sizes, and colors in modern dogs. Providing scientific insight into these adaptive stages, Sykes focuses attention on our own species, and how our own evolution from (perhaps equally aggressive) primates was enhanced by this most unlikely ally. Whether examining our obsession with canine purity, or delving into the prehistoric past to answer the most fundamental question of all, “Why do we love our dog so much?,” Once a Wolf is an engaging work no dog lover or ancestry aficionado should be without.

Sykes (The Seven Daughters of Eve), an Oxford genetics professor, delivers an uneven look at how wolves evolved alongside humans into docile companions and helpers. The book is rich with details about how humans have studied and shaped dog evolution, including profiles of researchers Shaun Ellis and Farley Mowat, who studied dogs’ evolutionary roots by living among wolf packs in the wild; and dog breeding case studies, such as how Victorian naturalist and sportsman Dudley Coutts Marjoribanks engineered the golden retriever to include “all the features required for a modern gun-dog.” Sykes also explores the diverse relationships humans have with dogs, or dog surrogates, ranging from working dogs on a New Zealand wool farm to the companionship between a Scottish academic and his robotic dog. Along with an obvious fluency with genetics, Sykes also has a gift for rendering complex concepts, such as mitochondrial DNA or genetic microsatellites, accessible to lay readers. However, passages outside his specialty, such as a discussion of cave paintings or a selection of interviews with dog owners, can come across as filler. Including moments of fascinating history and insight alongside a few too many discursive moments, Sykes’s survey ends up being less than the sum of its parts. (Mar.)

Publishers Weekly

"In prose both scientific and poetic, geneticist and author (DNA USA, 2012) Sykes, self-described as "not a dog person" but curious about the parallel evolution of dog and human, takes us through the archaeological, paleontological, behavioral, and genetic evidence pinpointing the transformation of wolf to dog. . . Woven throughout are possible answers to why humans are so in love with their dogs, making for a warmly engaging popular-science read."

How did wolves evolve into dogs? Sykes (Genetics/Oxford Univ.; The Nature of the Beast, 2015, etc.) reviews the state of the art on matters canine and lupine.

Past studies of canine evolution have relied on osteological and archaeological evidence, but since 2005, the fully sequenced dog genome has been available, allowing, among other things, for "re-drawing the evolutionary tree of dog breeds constructed with mitochondrial DNA over twenty years previously." Five years later, writes the author, a new family tree was published, with all 64 breeds—even the Chihuahua—pointing back to the wolf. Some of those breeds are "ancient," such as the Basenji and Samoyed; others are quite recent. Making those breeds required domestication, for which Sykes finds no evidence before about 50,000 years ago—still far earlier than previous studies have projected. Like other scholars, the author locates that origin in shared hunting, a process that may have altered humans as much as dogs in "the unstoppable current of natural selection." Scholarly argument persists over whether the original raw materials of the dog were really wolves and not coyotes, jackals, hyenas, and other canids. Sykes charts the development of the Carnivora before settling, persuasively, on the scenario of Paleolithic hunters working in concert with wolves to bring down large game such as bison. The author goes on to examine some of the mutations that subsequently allowed human breeders to select for certain characteristics, whether the ridge of the ridgeback or the pigmentation of the bull terrier (with a passing nod to the heterochromia exhibited by David Bowie's Ziggy Stardust). Melanism, hyperuremia, progressive rod-cone retinal degeneration: The author's discussion can be densely technical at times but never enough to render the text inaccessible to those without a background in genetics and population dynamics. Moreover, he closes by looking outside of nature to find the nurture connected to our love of dogs, that "amazing psychic symbiosis."

Scientifically inclined dog lovers will find this a trove of information and provocation.
