• [History of life: Grades 9-12] Present-day species evolved from earlier species; the relatedness of organisms is the result of common ancestry. (LS4.A)
• [History of life: Grades 6-8] Life forms of the past were in some ways very different from living forms of today, but in other ways very similar. (LS4.A)
• [History of life: Grades 6-8] Present-day life forms are descended from past life forms; all life is related. (LS4.A)
• [Evidence of evolution: Grades 6-8] An organism's features reflect its evolutionary history.
• [Evidence of evolution: Grades 6-8] Fossils provide evidence of past life. (LS4.A)
• [Evidence of evolution: Grades 6-8] The fossil record contains organisms with transitional features.
• [Evidence of evolution: Grades 6-8] There are similarities and differences among fossils and living organisms. (LS4.A)
• [Evidence of evolution: Grades 9-12] The fossil record provides evidence for evolution.
