State frameworks - Evolution
Central Concepts: Central Concepts: Evolution is the result of genetic changes that occur
in constantly changing environments. Over many generations, changes in the genetic makeup of populations may affect biodiversity through speciation and extinction.

Explain how evolution is demonstrated by evidence from the fossil record,
comparative anatomy, genetics, molecular biology, and examples of natural selection.

Describe species as reproductively distinct groups of organisms. Recognize that
species are further classified into a hierarchical taxonomic system (kingdom,
phylum, class, order, family, genus, species) based on morphological, behavioral, and
molecular similarities. Describe the role that geographic isolation can play in
speciation.

Explain how evolution through natural selection can result in changes in biodiversity
through the increase or decrease of genetic diversity within a population.
