HS-LS4 Biological Evolution: Unity and Diversity

• HS-LS4-1
  Communicate scientific information that common ancestry and biological evolution are supported by multiple lines of empirical evidence.
• HS-LS4-2
  Construct an explanation based on evidence that the process of evolution primarily results from four factors: (1) the potential for a species to increase in number, (2) the heritable genetic variation of individuals in a species due to mutation and sexual reproduction, (3) competition for limited resources, and (4) the proliferation of those organisms that are better able to survive and reproduce in the environment.
• HS-LS4-3
  Apply concepts of statistics and probability to support explanations that organisms with an advantageous heritable trait tend to increase in proportion to organisms lacking this trait.
• HS-LS4-4
  Construct an explanation based on evidence for how natural selection leads to adaptation of populations.
• HS-LS4-5
  Evaluate the evidence supporting claims that changes in environmental conditions may result in: (1) increases in the number of individuals of some species, (2) the emergence of new species over time, and (3) the extinction of other species.
• HS-LS4-6
  Create or revise a simulation to test a solution to mitigate adverse impacts of human activity on biodiversity.
