A biological adaptation is any structural (morphological or anatomical), physiological, or behavioral characteristics of an organismor group of organisms (such as species) that make it better suited in its environment and consequently improves its chances of survival and reproductive success. Due to individual phenotypic plasticity (variability), individuals will be more or less successful. Some adaptations may improve reproductive success of the population, but not a particular individual, such as seen in altruistic behavior in social insects.
Organisms that are adapted to their environment are able to :
secure food, water, and nutrientsobtain air, warmth, and spacescope with physical conditions such as temperature, light, and heatdefend themselves from their natural enemiesreproduce and rear offspringrespond to changes around them
Adaptation occurs in response to changes in the environment, life style, or relationship to other organisms. Environmental dynamicity, voluntary or compelled shifting of habitat, and human activities may put organisms in a new niche or in environmental stresses or pressures. In such circumstances, the organisms require characteristics suitable to the new situation. Organisms that are not suitably adapted to their environment will either have to move out of the habitat or die out. The term die out in the context of adaptation means that the death rate over the entire population of the species exceeds the birth rate for a long enough period for the species to disappear.
While adaptations provide for the individual purpose of the organism—survival, reproduction, development, maintenance—these same characteristics provide diversity and add to human fascination with, and enjoyment of, nature. Furthermore, while adaptations often are seen as a static set of suitable characteristics, in reality the process of developing adaptations is a dynamic process. Whether envisioned as the product of design or natural selection, or natural selection on the microevolutionary level and design for macroevolutionary changes, the reality is that new adaptations are needed when organisms encounter new environments, and such have arisen for millions of years.
In some extreme conditions, it is possible for the previous adaptation to be poorly selected, the advantage it confers over generations decreasing, up to and including the adaptation becoming a hindrance to the species' long–term survival. This is known as maladaptation.
There is a great difference between adaptation and acclimation or acclimatization. The process of developing adaptations occurs over many generations; it is a population phenomenon involving genetics and is generally a slow process. Acclimation or acclimatization, on the other hand, generally occurs within a single lifetime or instantly and deals with issues that are less threatening. For example, if a human being were to move to a higher altitude, respiration and physical exertion will become a problem. However, after spending a period of time under the high altitude conditions, one may acclimatize to the reduced pressure, the person's physiology may function normally, and the change will no longer be noticed.
