QUESTION: What is evolution? As it is most famously used, evolution is the process by which an organism becomes more sophisticated over time and in response to its environment. The Theory of Evolution is currently the most popular concept of how life reached its current state.
evolution. the process of development in which an organ or organism becomes more and more complex by the differentiation of its parts; a continuous and progressive change according to certain laws and by means of resident forces. convergent evolution. the development, in animals that are only distantly related, of similar structures or functions in adaptation to similar environment. divergent evolution. the development of different characteristics in animals that were closely related in response to being placed in different environments.
