Here's a simplified explanation:
* Thousands of years ago: Wolves lived in many parts of the world.
* Early humans: Some wolves may have been attracted to human settlements, scavenging for food scraps.
* Domestication: Over time, humans started selectively breeding the wolves that were most friendly and useful, resulting in changes in behavior and physical traits.
* Evolution: This process of selective breeding continued over generations, leading to the wide variety of dog breeds we have today.
Important Note: While we know dogs evolved from wolves, the exact process and timing of this domestication are still being studied by scientists.
