Evolution Of The Earth

Understanding evolution of the earth requires examining multiple perspectives and considerations. Evolution - Wikipedia. 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 | Definition, History, Types, & Examples | Britannica. Evolution, theory in biology postulating that the various types of living things on Earth have their origin in other preexisting types and that the distinguishable differences are due to modifications in successive generations.

Theory of Evolution - National Geographic Society. 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. An introduction to evolution.

Evolution helps us to understand the living world around us, as well as its history. Biological evolution is not simply a matter of change over time. What is the Theory of Evolution?

Although the idea that life evolves wasn’t entirely new in the 19th century, it was Charles Darwin who transformed it into a scientific theory. EVOLUTION Definition & Meaning - Merriam-Webster.
