Breah Chapter 14 XC

6. Study of where organisms live and how they are distributed.
13. Related species become more different over time.
15. Rapid evolution of many species from one ancestor.
17. species Organism showing traits between ancestral and modern groups.
19. Reduced or unused body parts inherited from ancestors.
20. Human breeding of organisms for desired traits.
21. Change in species over time through inherited traits.
22. Process where organisms with helpful traits survive and reproduce more successfully.

1. Theory that species change over generations and share common ancestors.
2. Age of a rock or fossil compared to others.
3. Diagram showing evolutionary relationships among species.
4. Study of embryos and early development of organisms.
5. Body parts with similar structures due to common ancestry.
7. Two species evolving in response to each other.
8. Unrelated species evolve similar traits independently.
9. Inherited trait that helps an organism survive and reproduce.
10. Traits gained during life that were once thought to be passed to offspring.
11. Ability of an organism to survive and reproduce in its environment.
12. Exact age of a rock or fossil, often measured in years.
14. Idea that Earth’s features formed through sudden disasters.
16. Body parts with similar functions but different evolutionary origins.
18. Layers of rock or soil with different ages.
