Chapter 21
The Evolution of Populations
Essential Knowledge:
1.A.1: Natural selection is a major mechanism of evolution.
1.A.2: Natural selection acts on phenotypic variations in populations.
1.A.3: Evolutionary change is also driven by random processes.
1.A.4: Biological evolution is supported by scientific evidence from many disciplines, including mathematics.
1.B.1: Organisms share many conserved core processes and features that evolved and are widely distributed among organisms today.
1.C.3: Populations and organisms continue to evolve.
3.A.3: The chromosomal basis of inheritance provides an understanding of the pattern of passage (transmission) of genes from parent to offspring.
3.C.2: Biological systems have multiple processes that increase genetic variation.

As you complete test, mark questions with:
a star (I know this),
a checkmark (I might know this),
or a question mark (I don't know, I guessed).
Self-correct.
Write validations/corrections for checkmarks, question marks, and missed stars (oops).
