  • [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.
  • [History of life: Grades 6-8] 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.
  • [History of life: Grades 6-8] Present-day life forms are descended from past life forms; all life is related. (LS4.A)
  • [History of life: Grades 9-12] 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.
  • [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.
  • [Studying evolution: Grades 6-8] Classification is based on evolutionary relationships.
  • [Studying evolution: Grades 6-8] Evolutionary relationships may be represented by branching trees (i.e. phylogenies or cladograms).
  • [Studying evolution: Grades 9-12] Classification is based on evolutionary relationships.
  • [Studying evolution: Grades 9-12] Evolutionary trees (i.e. phylogenies or cladograms) portray hypotheses about evolutionary relationships.
  • [Studying evolution: Grades 13-16] Classification is based on evolutionary relationships.
  • [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.
