What does instinctive behavior refer to in animals?

Instinctive behavior in animals refers to actions or responses that are inherent and largely unlearned, meaning they are part of the animal's genetic makeup and are present from birth. This type of behavior is often crucial for survival since it allows animals to perform essential functions such as finding food, escaping predators, and reproducing without needing prior experience or external instruction. For instance, a newborn sea turtle instinctively moves toward the ocean immediately after hatching, which is crucial for its survival.

This concept distinguishes instinctive behaviors from learned behaviors, which are acquired through interaction with the environment, experience, or training. While instinctive behaviors are consistent and predictable, learned behaviors can vary widely between individuals based on their unique experiences and environments, leading to a significant contrast with instinctive actions.
