Correspondence to the Next Generation Science Standards is indicated in parentheses after each relevant concept. See our conceptual framework for details.

  • There is a fit between organisms and their environments, though not always a perfect fit. (LS4.C)

  • Depending on environmental conditions, inherited characteristics may be advantageous, neutral, or detrimental.

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

  • Scientists can test ideas about events and processes long past, very distant, and not directly observable.

  • Scientific knowledge is open to question and revision as we come up with new ideas and discover new evidence. (P4, P6, NOS3)

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

  • As with other scientific disciplines, evolutionary biology has applications that factor into everyday life.

  • There is a fit between the form of a trait and its function, though not always a perfect fit.
