From Wild Wolves to Loyal Dogs: How Tameness Shaped Domestication
Domestication is a process that occurs over many generations as a population or species of animals becomes adapted to living with humans in a captive environment.
Tameness develops within an animal’s lifetime. Scientists define it as an animal’s willingness to approach humans and measure it by flight distance—the distance at which the animal retreats. A tame animal has a flight distance of zero, meaning a person can approach without causing it to flee. An animal with a 10-foot flight distance allows a person to come within 10 feet before running away. Dogs and cats raised in the wild are domesticated but may not be tame if they lacked human handling when young.
The difference between tameness and domestication helps explain how wolves may have gradually developed into dogs.
One hypothesis proposes that when humans established permanent settlements, they also created trash sites that wolves began using as food sources. The tamest and least fearful wolves were better able to scavenge near people, making them more likely to survive and reproduce. Their pups inherited some of this tameness and gained the same survival advantage. Over many generations, this process produced village dogs in settlements around the world. In this way, tameness allowed individual wolves to live near humans, while domestication gradually transformed their descendants into dogs.
