Population Genetics evo-edu.org

Landscape genetics and spatial population-change materials for movement, barriers, and population structure.

Standards

Gene Flow Mapper standards and alignment

This page maps the app to standards-facing classroom use while staying explicit about model limits and evidence expectations.

Alignment Notes

  • NGSS HS-LS4-1: Communicate scientific information that common ancestry and biological evolution are supported by multiple lines of evidence.
  • NGSS HS-LS2-6: Evaluate claims and design reasoning around factors that affect ecosystem dynamics and populations.
  • Practices: developing and using models, analyzing and interpreting spatial patterns, revising explanations from evidence.

What learners should produce

Minimum evidence

  • A prediction about what movement or barriers should do.
  • A comparison of at least two conditions.
  • An explanation distinguishing gradual separation from abrupt separation.

Model limits to keep visible

  • The direct public workbench shows a summary view, not the full spatial grid.
  • The legacy detailed map remains useful when learners need cell-level pattern inspection.
  • Observed model behavior supports reasoning about fragmentation and gene flow, not automatic real-world certainty.
