• [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 13-16] Present-day species evolved from earlier species; the relatedness of organisms is the result of common ancestry.
• [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] Evolutionary trees (i.e. phylogenies or cladograms) portray hypotheses about evolutionary relationships.
• [Studying evolution: Grades 9-12] As with other scientific disciplines, evolutionary biology has applications that factor into everyday life.
• [Studying evolution: Grades 13-16] Evolutionary trees (i.e., phylogenies or cladograms) portray hypotheses about evolutionary relationships.
• [Studying evolution: Grades 13-16] Evolutionary trees can be used to make inferences and predictions.
• [Studying evolution: Grades 13-16] As with other scientific disciplines, evolutionary biology has applications that factor into everyday life, for example in agriculture, biodiversity and conservation biology, and medicine and health.
