BI. 8. a. Students know how natural selection
determines the differential survival of groups of
organisms.
BI. 8. b. Students know a great diversity of
species increase the chance that at least some
organisms will survive major changes in the
environment
BI. 8. e Students know how to analyze fossil
evidence with regard to biological diversity,
episodic speciation, and mass extinction.
