ad·ap·ta·tion
(ăd′ăp-tā′shən) A change or adjustment in an animal or plant that increases its chance of survival in a specific environment. Adaptation can involve changes in a body part or in behavior: Wings are an adaptation of the forelimbs of a bird for flight.
Did You Know? The gazelle is extremely fast, and the cheetah is even faster. These traits are adaptations—characteristics or behaviors that give an organism an edge in the struggle for survival. Darwinian theory holds that adaptations are the result of a two-stage process: random variation and natural selection. Random variation results from slight genetic differences. For example, one cheetah in a group may be slightly faster than the others and thus have a better chance of catching a gazelle. The faster cheetah therefore has a better chance of being well-fed and living long enough to produce offspring. Since the cheetah's young have the same genes that made this parent fast, they are more likely to be fast than the young of slower cheetahs. The process is repeated in each generation, and thereby great speed becomes an adaptation common to cheetahs. This same process of natural selection also favors the fastest gazelles.

Adaptation
cut the coat according to the cloth To live within one’s means; to adapt one-self to a situation. The implication is that given only enough cloth to make a waistcoat or vest, one cannot make a full-length coat. Thus, someone with limited funds should be prudent about expenses and not attempt to live beyond his means. Though first cited in the 16th century, the expression was already in common use at the time.
I shall cut my coat after the cloth. (John Hey wood, Dialogue Containing Proverbs and Epigrams, 1562)
stretch one’s legs according to the coverlet To live within one’s means; to adjust to a situation, especially a financial one. This uncommon expression alludes to the way in which one must conform to an undersized bed, being sure not to extend himself beyond the bounds of his coverlet, or bedspread. Figuratively, the expression implies that one must be certain not to overextend himself beyond his resources.
trim one’s sails To reshape or alter one’s opinion, position, or policy to fit the situation; to adapt one-self to the circumstances or the times. To trim the sails was originally a nautical expression meaning to adjust the sails of a ship according to the direction of the wind and the course of the vessel in order to gain the greatest possible advantage.
