Although the genetic variation on which natural selection works is based on random or chance elements, natural selection itself produces adaptive change—the very opposite of chance scientists also have gained an understanding of the processes by which new species originate.
To review, traditional mechanics theory says that the evolution process is entirely driven by differences in expressed phenotypic design between organisms that are then selected or rejected by natural selection. Evolution is the theory that all living forms came from ancient ancestors through a series of mutations, genetic drift, migration, and natural selection today’s descendants show an amazing amount of similarities and diversity. Natural selection is the only mechanism known to cause the evolution of adaptations, so many biologists would simply define an adaptation as a char- acteristic that has evolved by natural selection.
