· 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 helps us to understand the living world around us, as well as its history. · darwin and a scientific contemporary of his, alfred russel wallace, proposed that evolution occurs because of a phenomenon called natural selection. 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.

Biological evolution is not simply a matter of change over time. In the theory of natural selection, organisms produce more offspring than are able to survive in their environment.
