Adaptation is a term used to describe the process by which specific manifested characters, determined by populations of alleles (forms of a gene) change in a population through succeeding generations. The changes are specifically related to characteristics that improve the organism's ability to successfully reproduce (i.e., to produce offspring that are capable of reproducing). Often, adaptation is erroneously related to survival, but this relationship is secondary to the ability to produce offspring that can, in turn, reproduce. Obviously, however, organisms must survive at least until they are able to reproduce--and a certain degree of longevity may be required to successfully raise offspring so that they may reproduce. With adaptation a species undergoes modification that favor its reproducibility and survival in a given set of environmental condition. There is no adaptation at the level of the individual. Adaptation is found only in population genetics...
