• [Evidence of evolution: Grades 9-12] An organism's features reflect its evolutionary history.
• [Evidence of evolution: Grades 9-12] The fossil record contains organisms with transitional features.
• [Evidence of evolution: Grades 9-12] Similarities among existing organisms provide evidence for evolution. (LS4.A)
• [Evidence of evolution: Grades 9-12] Anatomical similarities of living things reflect common ancestry. (LS4.A)
• [Evidence of evolution: Grades 13-16] An organism's features reflect its evolutionary history.
• [Evidence of evolution: Grades 13-16] The fossil record provides evidence for evolution.
• [Evidence of evolution: Grades 13-16] The fossil record contains organisms with transitional features.
• [Evidence of evolution: Grades 13-16] Similarities among existing organisms (including morphological, developmental, and molecular similarities) reflect common ancestry and provide evidence for evolution.
• [Mechanisms of evolution: Grades 13-16] Evolution does not consist of progress in any particular direction.
• [Nature of science: Grades 9-12] A hallmark of science is exposing ideas to testing. (P3, P4, P6, P7)
• [Nature of science: Grades 9-12] Scientists can test ideas about events and processes long past, very distant, and not directly observable.
• [Nature of science: Grades 13-16] A hallmark of science is exposing ideas to testing.
• [Studying evolution: Grades 9-12] Scientists use the similarity of DNA nucleotide sequences to infer the relatedness of taxa. (LS4.A)
• [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 13-16] Scientists use multiple lines of evidence (including morphological, developmental, and molecular evidence) to infer the relatedness of taxa.
• [Studying evolution: Grades 13-16] Scientists use fossils (including sequences of fossils showing gradual change over time) to learn about past life.
