natural selection

the process by which such forces as competition, disease, and climate tend to eliminate individuals who are less well adapted to a particular environment and favor the survival and reproduction of better adapted individuals, thereby changing the nature of the population over successive generations. This is the fundamental mechanism driving the evolution of living organisms and the emergence of new species, as originally proposed independently by British naturalists Charles Darwin and Alfred Russel Wallace (1823–1913). See Darwinism; evolutionary theory; selection; survival of the fittest. Compare artificial selection.

proactive coping

proactive coping

a stress-management strategy that reflects efforts to build up resources that facilitate promotion toward challenging goals and personal growth. Proactive individuals are motivated to meet challenges, and they commit themselves to their own high standards. They see demands and opportunities in the distant future and initiate a constructive path of action toward meeting them. Stress is interpreted as eustress—that is, productive arousal and vital energy—and coping thus becomes goal management instead of risk management. In contrast to the other three types of coping proposed by German psychologists Ralf Schwarzer (1943–  ) and Nina Knoll, proactive coping does not arise from any negative appraisals, such as harm, loss, or threat. See also anticipatory coping; preventive coping; reactive coping.
