domestication of animals | * domestication of animals is distinct (different) from <u>'''taming'''</u> | ||
** taming = conditioning or changing the behavior of a wild animal to accept human presence | |||
** taming does not involve genetic modification via breeding | |||
* an animal is "domesticated" when traits are "selected for" by humans through breeding | |||
=== domesticated animal traits === | |||
* imprinting | |||
