instinctive behavior

Instinctive behavior refers to automatic actions that living beings perform without needing to learn or think about them. These behaviors are hardwired into an organism’s biology and are typically essential for survival, such as a bird building a nest or a human baby's reflex to grasp. They are instinctual because they occur naturally in response to specific stimuli, allowing animals and humans to react quickly to their environment without conscious effort. These innate responses have developed over generations to help species survive and thrive in their natural habitats.
