Correspondence to the Next Generation Science Standards is indicated in parentheses after each relevant concept. See our conceptual framework for details. - 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.
- Present-day life forms are descended from past life forms; all life is related. (LS4.A)
- Classification is based on evolutionary relationships.
- Evolutionary relationships may be represented by branching trees (i.e. phylogenies or cladograms).
