The scientific study of how living things are classified.

A system for giving each organism a two-word scientific name that consists of the genus name followed by the species name.

<p>There is great variation in all species. Organisms produce more offspring than can be supported by the environment. Thus they are locked in a constant struggle for existence. Individuals whose variations are well suited to the environment survive, produce offspring, and pass the variations to the offspring. Individuals whose variations are not well suited to the environment die or do not produce many offspring. Over time species change or evolve.</p> Signup and view all the answers
