Structures That Reveal Common Ancestry

Float like a butterfly, sting like a bee, check out wing shapes for common ancestry! Beginning biologists compare wings as analogous structures and discover that environment influences evolution of adaptations. A third activity relies on illustrations of mammal limb bones and coverings, but they are not provided. Visit the National Science Teachers Association website for links to student materials.
