Document Summary
Adaptions are biological traits that help an individual survive and reproduce in its habitat. Adaptions perform a specific function, that make an organism better suited to its environment. Ex. eyes enable you to recognize and respond to things by detecting and analyzing reflected light.

Psychologists are adaptations: they find it helpful to break down large-scale cognitive processes into adaptive problems or tasks, and to then look for the adaptations that solve those problems. Adaptions emerge in development as a result of the activation of relevant genes in interaction with relevant aspects of the environment. Natural selection: formalized by charles darwin and alfred russel wallace. One of the 4 mechanisms of basic evolution (others: mutation, genetic drift, migration) Definition: differential survival and reproduction of organisms as a result of the heritable differences between them.
