Across
  1. 4. The shared ancestor of all living organisms on Earth.
  2. 8. Early developmental stages of organisms, used to study evolutionary relationships.
  3. 9. The process of change in the genetic material of organisms over time.
  4. 11. Differences in traits among individuals within a population.
  5. 13. A trait that increases an organism’s ability to survive and reproduce.
  6. 15. The chemical instructions (DNA) that guide the growth and function of an organism.
  7. 17. The process by which one population splits and evolves into different species.
  8. 18. Processes within cells carried out by proteins to sustain life.
  9. 23. The Last Universal Common Ancestor, likely a single-celled organism.
  10. 26. The accumulation of genetic changes that lead to the creation of new species.
  11. 27. Segments of DNA inherited from parents or transferred between species.
  12. 28. A close relationship between two species living together.
  13. 30. Single-celled organisms that resemble LUCA and are among the simplest forms of life.
Down
  1. 1. A form of symbiosis where one organism lives inside another’s cells.
  2. 2. A tool used to magnify objects, like cells, for study; Darwin's had less than 200x magnification.
  3. 3. A marine ecosystem with an amazing variety of living organisms.
  4. 5. The study of embryos, providing evidence of evolutionary relationships.
  5. 6. A process that shapes evolution by favoring traits that increase fitness.
  6. 7. The ability of an organism to survive and reproduce in its environment.
  7. 10. Molecules that act as building blocks or perform functions in cells.
  8. 12. Small changes in genetic material within a species.
  9. 14. A protein that forms chains to make up muscle fibers.
  10. 16. The idea that one organism living inside another's cells led to complex life forms.
  11. 19. A species closely related to dogs based on DNA comparisons.
  12. 20. Preserved remains or impressions of organisms from the past, providing evolutionary evidence.
  13. 21. Changes in DNA that can lead to variations within a population.
  14. 22. A scientist who studied evolution using simple microscopes and hand tools.
  15. 24. Microorganisms similar to bacteria but with distinct evolutionary pathways.
  16. 25. The molecule used by all living organisms as genetic material.
  17. 29. A group of microorganisms similar to bacteria, related to LUCA.
