1. What term refers to the movement of a pathogenic or- Epizootic
ganism (a virus or bacterium) from an animal species
into humans?
2. What is the distinction between a theory and hypoth- A theory explains

of patterns and
data, and has
been well support-
ed by many empir-
ical tests, whereas
a hypothesis has

3. Does natural selection ALWAYS result in evolution? NO
4. Can natural selection occur without evolution? Yes
5. Can evolution occur without natural selection? Yes
6. Does natural selection operate on phenotypes? Yes
7. True or False: The expected frequency of any het- True
erozygote is two times the product of the respective
allele frequencies in a population following H-W as-
sumptions.
8. True or False: The expected frequency of any ho- True
mozygote is the square of the allele frequency in a
population following H-W assumptions.

16. The process of evolution via natural selection re- 1) limiting re-
quires several things, including...? (4) sources, and
therefore, some
kind of competi-

2) phenotypic vari-

influences how
well organisms
compete
3) a genetic basis
to the phenotypic
variation
4) an iteration of
