Scientific definition: an anatomical feature of living organisms that no longer retain their structure. Artificial selection an analogous process to natural selection. A selective breeding of animals or plants to ensure that certain desirable traits appear at higher frequency in successive generations. The evolutionary process by which alleles that increase the likelihood of survival and the reproductive output of the individuals that carry them become more common in subsequent generations. The fragmentation of continuous geographic distribution by non-biological factors. A species that occurs in only one place on earth. A cluster of closely related species that are adaptively specialized to specific habitat or food source. A pattern of postembryonic development in which parts of the same organism grow at different rates, the example of genitals can be used in this sense.
