This is a great lesson plan that combines Karoytypes and evolution. Students will recognize that the chromosomes of chimpanzees and humans are remarkably similar, then correlate that to their evolutionary relationship.

This lesson plan requires students to analyze DNA restriction maps to determine the differences in the sequence for several primates and humans. They then use the information to create a cladogram.

[Free Registration/Login Required] Match the animals with their embryos and answer questions about their evolutionary ancestry.

Explains what synapomorphy is by using examples to demonstrate the concept, which plays an important role in the system of cladistics.

Explains that analogous structures are ones that are similar in different organisms yet have no common ancestry. This type of phenomenon occurs with convergent evolution. Includes lots of examples for both animals and plants.

A textbook definition along with an explanation of the scientific theory of evolution.

In this informative site, homologous is defined and the wings of birds and bats are compared to clarify the concept.

Explains how the eyes of very diverse species have a common genetic ancestry.
