The process of evolution drives the diversity and unity of life
Enduring Understanding:
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.
Required Reading:
Campbell: Chapter 21(briefly), 22, 23, 24, 25, 26
Labs: BLAST Activity, Population Genetics Dry Lab
