Variation

• The fossils and their locations in the sedimentary layers of Earth's crust, which provide information about things that lived in the distant past

• Differences among individual entities

• Describes a long period of time in which little or no change occurs within a species

• The occurrence of an organism, trait, or gene in more than one form
