• [Evidence of evolution: Grades 13-16] The fossil record documents the biodiversity of the past.
• [Studying evolution: Grades 9-12] Scientists use fossils (including sequences of fossils showing gradual change over time) to learn about past life.
• [Studying evolution: Grades 9-12] Evolutionary trees (i.e. phylogenies or cladograms) portray hypotheses about evolutionary relationships.
