In this lesson, students study the embryos of different organisms at three stages of development to look for features that suggest a common ancestry.

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

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.
