Across
  1. 7. passing of traits from parents to offspring
  2. 8. type of selection that favors one extreme trait
  3. 9. body parts that have lost most or all of their original function
  4. 11. process where traits increase chances of attracting a mate
  5. 13. body parts with similar structure due to shared ancestry
  6. 15. Type of selection that is human controlled breeding to produce desired traits
  7. 17. with modification, idea that species change over time while sharing common ancestors
  8. 18. production of more offspring than can survive in the environment
  9. 20. study of early development of organisms
  10. 21. change in populations of living organisms over many generations
  11. 22. type of selection that favors average traits and reduces extremes
Down
  1. 1. type of selection that favors both extreme traits over the average
  2. 2. traits that help an organism survive and reproduce in its environment
  3. 3. ability of an organism to survive and reproduce in its environment
  4. 4. body parts with similar function but different evolutionary origins
  5. 5. law that states lower rock layers are older than higher layers
  6. 6. random change in DNA that can create new traits
  7. 10. process where organisms with helpful traits are more likely to survive and reproduce
  8. 12. differences in traits among individuals of the same species
  9. 14. study of how species are distributed across Earth
  10. 16. preserved remains or traces of ancient organisms
  11. 19. success, situation where some organisms survive and reproduce more than others
