Connected to enduring understandings:
1.A Change in the genetic makeup of a population over time is
evolution.
1.B Organisms are linked by lines of descent from common
ancestry.
1.C Life continues to evolve within a changing environment.
1.D The origin of living systems is explained by natural processes.
3.A Heritable information provides for continuity of life.
3.C The processing of genetic information is imperfect and is a
source of genetic variation.
4.C Naturally occurring diversity among and between components
within biological systems affects interactions
with the environment.
