Intro Evolution and Taxonomy Final Exam Review

The process by which organisms in nature with variations most suited to their local environment survive and leave more offspring.

• Common Descent

• Natural Selection

• Vestigial Structures

• Molecular similarities

Individuals with the average phenotype are better fit for the environment than the organisms with the extreme phenotypes.

• Stabilizing Selection

• Directional Selection

• Disruptive Selection

NGSS.HS-LS4-4

Individuals with one extreme phenotype have higher fitness and have more offspring than individuals with the average phenotype or the other extreme phenotype.

• Stabilizing Selection

• Directional Selection

• Disruptive Selection
