Teaching tips:
Use this resource to relate evolutionary concepts to the topic of carbon fixation (or get more suggestions for incorporating evolution throughout your biology syllabus). Incorporate these slides immediately after you’ve discussed C4 and CAM carbon fixation. Alternatively, you could incorporate your lecture material on the processes of C4 and CAM fixation into this slide set.

Concepts:
Correspondence to the Next Generation Science Standards is indicated in parentheses after each relevant concept. See our conceptual framework for details.

  • Through billions of years of evolution, life forms have continued to diversify in a branching pattern, from single-celled ancestors to the diversity of life on Earth today.

  • The early evolutionary process of eukaryotes included the merging of prokaryote cells.

  • An organism's features reflect its evolutionary history.

  • Similarities among existing organisms (including morphological, developmental, and molecular similarities) reflect common ancestry and provide evidence for evolution.

  • Not all similar traits are homologous; some are the result of convergent evolution.

  • Scientists can test ideas about events and processes long past, very distant, and not directly observable.

  • Evolutionary trees (i.e., phylogenies or cladograms) portray hypotheses about evolutionary relationships.

  • Evolutionary trees can be used to make inferences and predictions.
