Describe the scientific evidence that provides support for models of the origin of life on Earth.Unit 7:  Natural Selection
I can:
  • Describe the causes of natural selection.
  • Explain how natural selection affects populations
  • Describe the importance of phenotypic variation in a population
  • Explain how humans can affect diversity within a population.
  • Explain the relationship between changes in the environment and evolutionary changes in the population
  • Explain how random occurrences affect the genetic makeup of a population.
  • Describe the role of random processes in the evolution of specific populations.
  • Describe the change in the genetic makeup of a population over time
  • Describe the conditions under which allele and genotype frequencies will change in populations.
  • Explain the impacts on the population if any of the conditions of HardyWeinberg are not met.
  • Describe the types of data that provide evidence for evolution.
  • Explain how morphological, biochemical, and geological data provide evidence that organisms have changed over time
  • Describe the fundamental molecular and cellular features shared across all domains of life, which provide evidence of common ancestry
  • Describe structural and functional evidence on cellular and molecular levels that provides evidence for the common ancestry of all eukaryotes.
  • Explain how evolution is an ongoing process in all living organisms.
  • Describe the types of evidence that can be used to infer an evolutionary relationship
  • Explain how a phylogenetic tree and/or cladogram can be used to infer evolutionary relatedness
  • Describe the conditions under which new species may arise.
  • Describe the rate of evolution and speciation under different ecological conditions
  • Explain the processes and mechanisms that drive speciation.
  • Describe factors that lead to the extinction of a population.
  • Explain how the risk of extinction is affected by changes in the environment.
  • Explain species diversity in an ecosystem as a function of speciation and extinction rates.
  • Explain how extinction can make new environments available for adaptive radiation.
  • Explain how the genetic diversity of a species or population affects its ability to withstand environmental pressures. 
  • Describe the scientific evidence that provides support for models of the origin of life on Earth.
