Instinct
Instinct explained in an easy to understand way:
Imagine trying to assemble a piece of flat-pack furniture without any instructions, relying solely on intuition. This situation is similar to how animals rely on instinct, as they are born with an innate "instruction manual" that guides their behavior without needing to learn it from scratch. Just as your intuition helps you piece together the furniture by recognizing patterns and fitting parts together, an animal's instinct equips it with pre-programmed behaviors to help it navigate the world from birth.
Practice Version
Instinct: The pattern of behavior with which an animal is born instinct. Instinct is an automatic response or action that organisms are naturally equipped with to survive and reproduce.
