Here's a breakdown:
Physical Changes:
* Smaller size: Domesticated animals are often smaller than their wild counterparts. This is because they are not as reliant on survival skills like speed and strength.
* Less aggressive behavior: Domesticated animals are less likely to exhibit aggression towards humans or other domesticated animals.
* Variations in physical traits: Domesticated animals can exhibit a wide range of variations in their physical traits, such as fur color, size, and even body shape, due to selective breeding by humans.
Behavioral Changes:
* Socialization with humans: Domesticated animals are more accustomed to human interaction and often seek out human companionship.
* Reduced fear of humans: They have a lower fear response to humans, making them easier to handle and train.
* Increased dependence on humans: Domesticated animals often rely on humans for food, shelter, and protection.
Examples:
* Dogs: Originally descended from wolves, dogs have been domesticated for thousands of years, exhibiting a variety of physical and behavioral traits specific to their close relationship with humans.
* Cats: Domesticated cats have been bred for their companionship and hunting abilities, showing a range of colors, patterns, and personalities.
* Cattle: Domesticated cattle have been selectively bred for milk production, meat, and even their docile temperament.
Important Note: The process of domestication is complex and involves both human intervention and natural selection. The resulting changes can be profound, leading to significant differences between domesticated and wild animals.
