Cell Phone Evolution Vector Isometric 173882750 Shutterstock The scientific theory of evolution by natural selection was conceived independently by two british naturalists, charles darwin and alfred russel wallace, in the mid 19th century as an explanation for why organisms are adapted to their physical and biological environments. Evolution, theory in biology postulating that the various types of plants, animals, and other living things on earth have their origin in other preexisting types and that the distinguishable differences are due to modifications in successive generations.

Evolution is a process of continuous branching and diversification from common trunks. this pattern of irreversible separation gives life's history its basic directionality. Darwin and a scientific contemporary of his, alfred russel wallace, proposed that evolution occurs because of a phenomenon called natural selection. in the theory of natural selection, organisms produce more offspring than are able to survive in their environment. Evolution is the process by which species change over time through the gradual accumulation of genetic variations, driven by mechanisms like natural selection, genetic drift, and mutation, leading to the development of new traits or species.

Evolution explains how microscopic single celled organisms eventually gave rise to the vibrant explosion of life we see today. it tells us how species adapt, survive, diverge, and sometimes disappear. In biology, evolution is the change in the characteristics of a species over several generations and relies on the process of natural selection. Darwin published his theory of evolution in on the origin of species (1859), with carefully reasoned evidence to support this theory that all life on earth evolved from a common ancestor. Evolution can be seen as a two step process. first, hereditary variation takes place; second, selection is made of those genetic variants that will be passed on most effectively to the following generations.
