Concepts:
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)

  • Traits that confer an advantage may persist in the population and are called adaptations. (LS4.B, LS4.C)

  • Inherited characteristics affect the likelihood of an organism's survival and reproduction. (LS4.B, LS4.C)

  • Over time, the proportion of individuals with advantageous characteristics may increase (and the proportion with disadvantageous characteristics may decrease) due to their likelihood of surviving and reproducing. (LS4.B, LS4.C)

  • Evolution does not consist of progress in any particular direction.

  • Fitness is reproductive success - the number of viable offspring produced by an individual in comparison to other individuals in a population/species.
