Here's why:
* Instinct refers to a complex, unlearned behavior pattern characteristic of a species. These behaviors are often triggered by specific stimuli and are essential for survival.
* Reflexes are simpler, involuntary responses to a specific stimulus, like the knee-jerk reflex. While reflexes are also innate, they are not as complex as instincts.
Examples of instincts include:
* Birds building nests
* Spiders spinning webs
* Salmon swimming upstream to spawn
It's important to remember that while instincts are innate, they can be modified by learning and experience.
