(7) Science concepts. The student knows evolutionary theory is a scientific explanation for the unity and diversity of life. The student is expected to:

• (A) analyze and evaluate how evidence of common ancestry among groups is provided by the fossil record, biogeography, and homologies, including anatomical, molecular, and developmental; 
• (B) examine scientific explanations of abrupt
  appearance and stasis in the fossil record; 
• (C) analyze and evaluate how natural selection produces change in populations, not individuals;
• (D) analyze and evaluate how the elements of natural selection, including inherited variation, the potential of a population to produce more offspring than can survive, and a finite supply of environmental resources, result in differential reproductive success; 
• (E) analyze and evaluate the relationship of natural selection to adaptation and to the development of diversity in and among species; and 
• (F) analyze other evolutionary mechanisms, including genetic drift, gene flow, mutation, and recombination .
