Detailed explanation-1: -Which demonstrates how genetic variation may result from a change in the environment where an animal lives? An arctic fox changes its color over time because it migrates to an area with a different climate.
Detailed explanation-2: -Fossils. Fossils provide solid evidence that organisms from the past are not the same as those found today, and fossils show a progression of evolution. Scientists determine the age of fossils and categorize them from all over the world to determine when the organisms lived relative to each other.
Detailed explanation-3: -Using the principle of faunal succession, if an unidentified fossil is found in the same rock layer as an index fossil, the two species must have existed during the same period of time (Figure 4). If the same index fossil is found in different areas, the strata in each area were likely deposited at the same time.
Detailed explanation-4: -An index fossil is typically preserved in sedimentary rock layers.
