In this lesson, students will learn that geological time can be measured in several different ways, providing independent lines of evidence for measuring deep time and sequencing geological and biological events of the past. Students explore different methods of measuring geological time, comparing the time dimensions, mechanisms, and materials used for each.

In this lesson amino acid sequences in cytochrome-c are compared for several different animals, and the number of differences found are used to infer degrees of relationship. This data is also compared with a cladogram constructed for those same animals from their anatomical features, providing an example of independent confirmation.
