Unit 7: Natural Selection

BIG IDEA 1 Evolution- What conditions in a population make it more or less likely to evolve?
Scientifically defend the theory of evolution.
BIG IDEA 4 Systems Interactions-How does species interaction encourage or slow changes in species?

7.1.A- Describe the causes of natural selection.

7.2.B- Explain how natural selection affects populations.

7.2.A- Describe the importance of phenotypic variation in a population.

7.2.B- Explain how variation in molecules within cells connects to the fitness of an organism.

7.3.A-Explain how humans can affect diversity within a population.

7.4.A-Explain how random occurrences affect the genetic makeup of a population.

7.4.B-Describe the role of random processes in the evolution of specific populations.

7.4.C- Describe the change in the genetic makeup of a population over time.

7.5.A- Describe the conditions under which allele and genotype frequencies will change in populations.

7.6.A- Describe the types of data that provide evidence for evolution.

7.6.B-Explain how morphological, biochemical, and geological data provide evidence that organisms have changed over time.

7.7.A-Describe structural and functional evidence on cellular and molecular levels that provides evidence for the common ancestry of all eukaryotes.

7.8.A-Explain how evolution is an ongoing process in all living organisms.

7.9.A-Describe the types of evidence that can be used to infer an evolutionary relationship

7.9.B-Explain how phylogenetic trees and cladograms can be used to infer evolutionary relatedness.

7.10.A-Describe the conditions under which new species may arise.

7.10.B-Describe the rate of evolution and speciation under different ecological conditions.

7.10.C-Explain the processes and mechanisms that drive speciation.

7.11.A-Explain how the genetic diversity of a species or population affects its ability to withstand environmental pressures.
