Overview: Students observe that the banding patterns seen on stained chromosomes from humans and chimpanzees show striking similarities. Possible evolutionary relationships are explored, as are the chromosomes and relationships of other apes. Author/Source: ENSI Grade level: 9-12 Time: One to two class periods. Teaching tips: Students may need additional information about creating the phylogenetic tree in exercise 2. Concepts: Present-day species evolved from earlier species; the relatedness of organisms is the result of common ancestry. An organism’s features reflect its evolutionary history. Similarities among existing organisms provide evidence for evolution. All life forms use the same basic DNA building blocks. Scientists use the similarity of DNA nucleotide sequences to infer the relatedness of taxa. Teacher background: Genetic Variation Evidence for Evolution
