Unit 9 – Evolution
Understandings:
Understandings:
• Organisms can be classified into groups based on common characteristics
(anatomical/DNA similarities).
• Characteristics that organisms possess are passed through the genetic material
from generation to generation.
• Organisms develop adaptations genetically that change over time in response to
their environment.
• Scientific Inquiry is a thoughtful and coordinated attempt to search out, describe,
explain and predict natural phenomena.
• Scientific knowledge is derived from and supported by the results of many
individual experiments to establish patterns in the data, draw conclusions, and push
the thinking of the scientific community.
• Scientific information evolves with the addition of newly acquired data, rethinking
of existing data, and/or the advancement of tools.

Essential Questions:
Essential Questions:
1. How do these three components influence natural selection?
a. Inherited Variation (mutations)
b. Limited Resources
c. Production of More Offspring
2. What are the evidences of common ancestry among organisms?
3. How do different mechanisms, such as genetic drift, gene flow, mutation, and
recombination, lead to speciation?
