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. Full description.

This site describes the fossils found in the fossil-rich calcareous nodules (Swedish: orsten) which occur in dark organic-rich shales known as alum shales in the upper Middle Cambrian and especially the Upper Cambrian of the Cambrian continent Baltica. These fossil-rich nodules were known for a long time as a source of excellent macrofossils, but they also provide a number of incredibly well-preserved ... Full description.

This site describes the Ordovician period, which is best known for its diverse marine invertebrates, including graptolites, trilobites, brachiopods, and the conodonts (early vertebrates). A typical marine community consisted of these animals, plus red and green algae, primitive fish, cephalopods, corals, crinoids, and gastropods. The tectonics segment describes Gondwana, discusses the northwards drift ... Full description.

This demonstration of natural selection has students select candies from a bowl, giving them an opportunity to think about what traits brought about the survival of some candies. After this activity, students will realize that not every feature of an organism is an adaptation, but features often reflect their evolutionary history. Adaptations often persist in a population because they are in some ... Full description.
