This one species branched out over time, throwing off many new and diverse species. This mechanism of evolutionary change is called natural selection. When you break that statement down, you find that it really consists of six components.

Evolution is a gradual process in which something changes into a different and usually more complex or better form. {co|the term SOMETHING is not precise enough}--Pierre.brawand 15 mars 2012 à 17:19 (CET) Life on Earth began with one primitive species only ONE? Are you sure? How can you be sure?--Pierre.brawand 15 mars 2012 à 17:19 (CET). It changed gradually, taking several millions of years. This one species branched out over time, throwing off many new and diverse species. This mechanism of evolutionary change is called natural selection. When you break that statement down, you find that it really consists of six components.

What are the six components?

The six components are evolution, gradualism, speciation, common ancestry, natural selection, and nonselective mechanisms of evolutionary change. Let see each of these components closer.
