True/ False Questions.
The fossil record supports:
1. Change
2. Sexual selection
3. Stasis
4. Inheritance of acquired characteristics
Allopatric Speciation:
5. Is when there’s no geographic isolation
6. Depends upon high gene flow
7. Is a vicariance event
8. Is exemplified by squirrels in the grand canyon
9. Depends upon behavioral isolation
Non-adaptive evolution:
10. Occurs with genetic drift
11. Is more likely in large populations
12. Is stopped by gene flow
13. Can lead to heterozygosity

Alleles:
15. Can be homozygous
16. Occur at loci
17. Are inherited from both parents
18. Are alternative version of genes
19. Code for amino acids
Evolution:
20. Occurs through changes in gene frequencies in a population
21. Was first explined by Darwin through descent with
modification
22. Artificial selection refutes it
23. It shows patterns of transition
24. Is only evident in the fossil record
Mutations are:
25. Always beneficial
26. Occur when necessary
27. A change in base pairs
28. An origin of genetic variation
Write essays about the following.
1.What is Reverse Dimorphism? Describe an example.
2. Draw graphs showing normal developmental trajectory and then
how it can be altered by heterochrony to produce different end
results. State examples.
3. Describe the three germ layers and give several examples of
what each gives rise to.
4. What are the four determinants of development
(morphogenesis)? Give a brief definition of each and then
DESCRIBE one developmental experiment and what is showed.
6. Describe the process of blastulation (please include a drawing).
7. Describe the process of gastrulation (please include a drawing)
8. Give 2 examples of neurulation errors and their causes
9. What are 3 predictions of patterns of development of transitions
in
evolution? Give examples of each. (OR state the three predictions
one can make if he knows that evolution—descent with
modification—happens.)
10. What are the 2 points on Darwin’s “On The Origin of
Species”? Give brief description of each.
11. Give examples of non-adaptive evolution.
12. What are the three modes of selection in adaptive evolution?
Draw a graph for each and give an example of each.
13. Discuss the relationship between parental investment, sexual
selection, and sexual dimorphism. Please graph the proper curve
that
represents STRONG dimorphism to monomorphic VS. ratio of
male to female parental investment.
14. What one factor is central to all concepts of speciation? Justify.
15. Make a list of prezygotic and post-zygotic isolating
mechanisms, with examples of each.

change” given in class? Describe each model.
