Where did Darwin make his most amazing observations?
What did he observe about the tortoises?
What did his observations make him think?
What did Hutton and Lyell propose?
What did Lamarck propose?
Why did Darwin think that the Galapagos finches descended from a common ancestor?
What is the difference between artificial selection and natural selection?
What does “survival of the fittest” mean?
9. ________________is the ability of an organism to survive and reproduce in its specific environment.
10. According to Darwin’s theory of _____________________________, the individuals that tend to survive are
those that have variations that best suit the environment.
11. What is a vestigial structure? List 3 examples.
12. The number and location of bones of many fossil vertebrates are similar to those in living vertebrates. Most
biologists would probably explain this fact on the basis of ________________ ancestor.
13. The similarities in embryonic development suggests that these organisms may share a _______________ancestor.
14. Charles Darwin viewed the __________________ record as a detailed record of _____________________ that
related extinct animals to modern animals.
15. How have horses changed over time?
16. Define evolution by natural selection-- ______________________________________
17. Define population--________________________________________________
18. Define Gene pool--_________________________________________________
19. Gene pools contain 2 or more _____________for a particular trait.
20. If an allele makes up one half of a population’s alleles for a given trait, its relative frequency is
_______________.
21. Define mutation--___________________________________________________
22. What are the 2 main sources of genetic variation?
23. A single-gene trait that has two alleles and that shows a simple dominant-recessive pattern will result in how
many phenotypes?
24. The number of phenotypes produced for a given trait depends upon number of ___________that control a trait.
25. The phenotypes for a typical polygenic trait can often be expressed as a ___________________ curve.
26. A polygenic trait can have many possible __________________ that give many possible
_____________________.
27. What are the 3 kinds of selection for populations?
28. Genetic drift tends to occur in populations that are __(large/small)________.
29. Define genetic equilibrium--_________________________________________________
30. Define geographic isolation, temporal isolation and behavioral isolation.
31. Although his idea was incorrect, Jean-Baptiste Lamarck was one of the first people to propose a scientific
explanation for ____________________.
32. Certain animal structures that have different functions in different species and develop from the same embryonic
tissues are called ____________________ structures.
33. If two populations have been reproductively isolated and can no longer breed and produce fertile offspring, the
process of _________________________ has occurred.
34. Why might a geographic barrier such as a large river cause the formation of a new species of small rodents but not
a new species of birds?
