Natural behavior refers to the instinctive actions and reactions of animals and humans in their typical environments. These behaviors are often driven by biological needs, such as finding food, mating, and avoiding predators. For example, a deer may freeze in place when it senses danger, a natural response to evade detection. In humans, natural behavior can include social interactions, communication, and emotional responses. These behaviors are influenced by both genetics and environmental factors. For instance, a child may naturally seek comfort from a parent when feeling scared, demonstrating an instinctive need for safety and support.
