Domestication Timeline indicates that dogs separated from wolves around

Domestication Timeline indicates that dogs separated from wolves around

• A. 2 million years ago
• B. 10,000 - 20,000 years ago
• C. 80,000 - 130,000 years ago
• D. 1,000 years ago

Answer: (C)

The idea being tested is that estimates for when dogs split from their wolf ancestors can vary, and the timeline depends on the data source and method used. In the timeline referenced here, the divergence of dogs from wolves is placed around 80,000 to 130,000 years ago. This reflects genetic and evolutionary work that suggests the lineages began to separate long before humans started selecting traits or producing the first recognizable domestic dogs. It’s important to separate this split from domestication itself—the actual process of selecting dogs for human purposes happened later and is why fossil evidence of archaeologically recognizable dogs appears much more recently. The other dates don’t fit this particular timeline. Two million years ago is earlier than most estimates for this split; 10,000–20,000 years ago is a more recent window that some sources cite, but it doesn’t match the timeline used in this question; and 1,000 years ago is far too recent to reflect the initial divergence of dog from wolf lineages.
