Which animal was domesticated earliest according to the timeline?

• A. Dogs
• B. Sheep
• C. Pigs
• D. Llamas

Answer: (A)

Dogs were the first animals humans domesticated, with evidence spanning archaeology and genetics showing a long history of living alongside people tens of thousands of years ago—often estimated around 20,000 to 40,000 years ago. This early bond predates the domestication of other animals listed, which occurred much later: sheep about 10,000–11,000 years ago in the Near East, pigs roughly 9,000–10,000 years ago in various regions, and llamas around 5,000–6,000 years ago in the Andes. Because the earliest signals of domestication appear with dogs, they are the correct answer.
