• [History of life: Grades 13-16] Present-day species evolved from earlier species; the relatedness of organisms is the result of common ancestry.
• [History of life: Grades 13-16] Biological evolution accounts for diversity over long periods of time.
• [History of life: Grades 13-16] Through billions of years of evolution, life forms have continued to diversify in a branching pattern, from single-celled ancestors to the diversity of life on Earth today.
• [Evidence of evolution: Grades 13-16] An organism's features reflect its evolutionary history.
• [Evidence of evolution: Grades 13-16] Similarities among existing organisms (including morphological, developmental, and molecular similarities) reflect common ancestry and provide evidence for evolution.
• [Evidence of evolution: Grades 13-16] Not all similar traits are homologous; some are the result of convergent evolution.
• [Studying evolution: Grades 13-16] Evolutionary trees (i.e., phylogenies or cladograms) portray hypotheses about evolutionary relationships.
• [Studying evolution: Grades 13-16] Evolutionary trees (i.e., phylogenies or cladograms) are built from multiple lines of evidence.
• [Studying evolution: Grades 13-16] The principle of parsimony suggests that the phylogenetic hypothesis most likely to be true is the one requiring the fewest evolutionary changes.
• [Studying evolution: Grades 13-16] Evolutionary trees can be used to make inferences and predictions.
