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.

  • The patterns of life's diversity through time provide evidence of evolution. (LS4.A)

  • Fossils provide evidence of past life. (LS4.A)

  • There are similarities and differences among fossils and living organisms. (LS4.A)

  • A hallmark of science is exposing ideas to testing. (P3, P4, P6, P7)

  • Scientists test their ideas using multiple lines of evidence.

  • Our knowledge of the evolution of living things is always being refined as we gather more evidence.

  • Scientists use anatomical features to infer the relatedness of taxa. (LS4.A)

  • Classification is based on evolutionary relationships.
