What Is Adaptation?
evolution does not consciously guide the development of organisms, and nothing evolved for a specific aim. alternatively, development is random and determined by survival, producing mutations that result in a genetically deviate population. In any given species, each animal may have slightly different genes or capabilities. When environmental pressures make one trait more useful than another, animals with that genetic trait are more probably to survive. For case, the big, building complex brains of humans could be an adaptation that allowed early people to travel, communicate, solve complex environmental problems, and develop settled civilizations .
An adaptive trait stands in contrast to a maladaptive trait—a trait that makes an organism less disposed to deal with its environment and more probably to die off .

General adaptation syndrome takes space in three stages, which are :
- Alarm reaction: This stage is when one’s fight or flight response kicks in. Stress hormones, including cortisol and adrenaline, are released. Someone may experience an increased heart rate and blood pressure when the alarm reaction takes place.
- Resistance: The resistance stage focuses on balancing the hormones and physiological responses that were triggered during stage one. If the stressor is gone during the resistance stage, the body’s responses will return to normal; if the stress persists, the body will remain in stress-response mode.
- Exhaustion: People who experience stress for a prolonged amount of time may find themselves in the exhaustion stage. This occurs when the body’s alarm reaction was triggered and did not dissipate, draining the body of its energy.
