The Evolutionary Journey of Dogs From Wolves to Companions
Summary
Dogs descended from ancient wolves and became humanity’s oldest domesticated species through a long, gradual process shaped by hunting-gathering societies, scavenging, and co-evolution. Genetic and archaeological evidence suggests domestication began tens of thousands of years ago and later expanded into herding, guarding, and companionship roles.
Key Points
- Dogs are direct descendants of extinct Pleistocene wolves and were domesticated long before the rise of agriculture.
- The article argues that dog domestication may have occurred through self-domestication, with less fearful wolves scavenging near human camps.
- Genetic evidence points to adaptations in starch digestion, stress response, and social behavior, while archaeological finds trace early dog remains across Eurasia.
- As agriculture spread, dogs took on new roles as herders, guardians, and cultural symbols in human societies.
