Adaptations in humans can be physiological, genetic, or cultural, which allow people to live in a wide variety of climates. There has been a great deal of research done on developmental adjustment, acclimatization , and cultural practices, but less research on genetic adaptations to colder and hotter temperatures.
In behavioral ecology, adaptive behavior is any behavior that contributes directly or indirectly to an individual's reproductive success, and is thus subject to the forces of natural selection. [1] Examples include favoring kin in altruistic behaviors , sexual selection of the most fit mate, and defending a territory or harem from rivals.
A psychological adaptation seen universally in humans is to easily learn a fear of snakes. [1] A psychological adaptation is a functional, cognitive or behavioral trait that benefits an organism in its environment. Psychological adaptations fall under the scope of evolved psychological mechanisms (EPMs), [2] however, EPMs refer to a less ...
For example, a constant repetitive action could be re-focused on something that creates or builds something. In other words, the behavior can be adapted to something else. In contrast, maladaptive behavior is a type of behavior that is often used to reduce one's anxiety, but the result is dysfunctional and non-productive coping. For example ...
Human behavioral ecology (HBE) or human evolutionary ecology applies the principles of evolutionary theory and optimization to the study of human behavioral and cultural diversity. HBE examines the adaptive design of traits , behaviors , and life histories of humans in an ecological context.
First studied as an adaptive mechanism specific to humans, [1] cognitive specialization has since evolved to encompass many behaviors in the social realm. Organisms have evolved over millions of years to become well-adapted to their habitats; this requires becoming specialized in behaviors that improve an organism's likelihood of survival and reproduction.

Due to the various changes experienced throughout life, humans and animals have to regularly learn how to adjust to their environment. Throughout our lives, we encounter various phases that demand continuous adjustment, from changes in career paths and evolving relationships to the physical and psychological shifts associated with aging.
