  • Evolution results from selection acting upon genetic variation within a population. (LS4.B)

  • 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.

  • Rates of evolution vary.

  • Evolutionary trees (i.e., phylogenies or cladograms) portray hypotheses about evolutionary relationships.
