Reproduction The first six characteristics of life, which was just considered, apply to individual organisms over the "short run." Over the long run, another universal characteristic of life is BIOLOGICAL EVOLUTION, which refers to the phenomenon that populations of organisms change from generation to generation. As a result of evolution, organisms may…
