What is the term for animals that can breed on their own but have undergone physiological or behavioral changes due to captivity?

The term that describes animals capable of breeding on their own but exhibiting physiological or behavioral changes due to captivity is semi-domesticated animals. These animals have not been fully domesticated and still retain aspects of their wild ancestry, which may influence their breeding habits and natural behaviors. Semi-domesticated animals often live in environments close to human habitation but are not completely reliant on humans for survival. This distinction highlights their adaptability and the intersection of wild traits and human influence.

Domesticated animals, on the other hand, have undergone extensive changes through selective breeding, typically resulting in dependence on humans for reproduction and survival. Wild animals exist entirely in their natural habitats and are characterized by behaviors and traits that have not been altered by human interaction. Endangered species are those at risk of extinction, which does not inherently relate to their ability to breed on their own or their status in captivity. Thus, semi-domesticated animals accurately reflects the nuanced relationship between the animal’s ability to reproduce independently and the effects of captivity on their behavior and physiology.
