Grade 7 natural selection is a population process: variation, heredity, and unequal survival or reproduction. Students use fossils, anatomy, and molecular clues as evidence of change over time. Adaptations are heritable traits that already help in a given environment; individuals do not evolve by trying during one lifetime.

A useful tip

Selection acts on variation that already exists. Individuals with traits that fit the current environment tend to leave more offspring; they do not stretch a body part and then pass on that stretch.
