Who originated the idea of a "struggle for existence" among organisms competing for limiting
resources?
The pampas of Argentina and the grasslands of Australia are populated by mammals that are
superficially similar and play similar ecological roles, but are not closely related. This is an
example of:
What generates the most genetic variation in a population of sexually reproducing organisms?
Which of these structures is a vestigial structure?
What causes the similarity in homologous structures?
How does a large, well adapted population change, evolutionarily, and why? (in terms of the
predictions of punctuated equilibrium).
Which of these is an example of a developmental changes be cued by the environment, which is
an adaptive 'acclimation'?
Which of the following is FALSE regarding genetic drift?
Which statement is FALSE regarding peripatric speciation
Who authored the theory of peripatric speciation?
The most impressive evolutionary changes are large-scale changes in body plan, like the
evolution of legs from fins. How do these changes probably occur?
What is the term for the genetic change that often occurs in a new population that colonizes a
new area, simply because of sampling error?
What is best defined as "differential reproductive success among genetically different
organisms."
When a population crashes due to exposure to a new illness, which genes are likely to
experience genetic drift and which will experience change in frequencies due to selection?
Which pair of structures are analogous structures?
1. Malthus
2. Community convergence
3. Independent assortment
4. Pelvis in a whale
5. Common ancestry
, 6. Changes a little because selection and drift are weak
7. Development of a ‘helmet’ by Daphnia in the presence of fish
8. It only occurs in small populations; large populations don’t experience it
9. It occurs when a population is divided in half by a barrier of inhospitable habitat (river,
canyon, road, field, burned lands, etc.)
10. Ernst Mayr
11. New regulatory patterns change how genes are expressed
12. Founder effect
13. Natural selection
14. Genes for resistance to the illness will be selected for, genes unrelated to the illness will
experience drift
15. Bat wing and insect wing
Which figure displays an 'interaction effect' between genetic and environmental effects that is
indicative of a response to selection (adaptation)?
Medicine has reduced death at childbirth dramatically, reducing the variance in offspring
survivorship. What has happened as a consequence?
What type of results are most indicative of 'adaptations'?
What is the best definition of sexual selection?
Which of the following is NOT a component of selection?
What causes the similarity in analogous structures?
At what temperature is pure water most dense?
What type of selection is most likely to lead to a polymorphic population?
Suppose we have 10 genotypes of a clonal plant. When we grow these plants under "ideal"
conditions, they grow to the same tall height. When we grow them in poor soil, they are grow
to the same short height. What is the primary determinant of plant height under these two
conditions?
This is a speciation event caused by populations diverging in different places; often under
different selective pressures.
In this type of selection, the modal, intermediate phenotype has highest reproductive success.
Selection for individuals with an intermediate phenotype is called:
resources?
