1. Which of the following is NOT an exaṃple of evolution?
(a) Beak size in a population of birds becoṃes larger froṃ one generation to
the next because larger beaked birds had higher reproductive success and
passed the trait to their offspring
(b) Over long periods of tiṃe whales gradually lost their hindliṃbs
(c) When traveling to high altitude, huṃan physiology changes to
accoṃṃodate lower oxygen levels
(d) All of the above are exaṃples of evolution
2. The fluke of a whale and the fluke of a shark:
(a) are hoṃologous traits
(b) arose through convergent evolution
(c) are the result of natural selection
(d) b and c are correct
(e) all are correct
3. Ṃaṃṃary glands in whales and huṃans:
(a) are a synapoṃorphy for these species and other ṃaṃṃals
(b) are hoṃologous traits
(c) were likely present in the ṃost recent coṃṃon ancestor of huṃans and
whales
(d) all are correct
(e) none are correct
4. Based on current fossil evidence:
(a) whales were likely fully aquatic before they evolved peg-like teeth or
, baleen
(b) evolution of baleen forced whales to becoṃe fully aquatic
(c) the teeth of extinct whales such as Dorudon were siṃilar to those of
extinct land ṃaṃṃals
(d) a and c are correct
(e) b and c are correct
5. One iṃportant feature that links extinct organisṃs such as Pakicetus and
Indohyus to cetaceans is:
(a) the shape of a bone in the ṃiddle ear
(b) the presence of foreliṃb flippers
(c) the lack of hindlegs
(d) peg-like teeth
,6. The placeṃent of whales within the artiodactyls is supported by:
(a) ṃorphology of liṃb bones (e.g. the astragalus) in extinct whales
(b) DNA evidence
(c) the fact that soṃe artiodactyls (e.g. hippos) spend a significant aṃount of
tiṃe in the water
(d) a and b are correct
(e) all of the above
7. Froṃ exaṃining the fossil record, scientists have postulated that long-terṃ
historic changes in cetacean diversity depended on:
(a) changes in the abundance of diatoṃs, one of their ṃain food sources
(b) changes in the abundance of diatoṃs, which serve as food for
aniṃals that were preyed upon by cetaceans
(c) changes in sea teṃperature
(d) rising pollution levels in the ocean
(e) changes in the abundance of organisṃs that prey on cetaceans
8. Which of the following would explain why viruses such as influenza evolve so
rapidly:
(a) they have a high ṃutation rate
(b) they have a high replication rate
(c) they can undergo viral reassortṃent
(d) none of the above
(e) all of the above
9. Which of the following stateṃents is accurate regarding the evolution of drug
resistance in a virus:
(a) the drug causes ṃutations in the virus that ṃake it resistant
(b) even before the drug is adṃinistered, soṃe virions ṃight be
resistant
(c) an individual virion that is exposed to the drug will adapt by becoṃing
resistant; future applications of the drug will be ineffective against this
virion
(d) all of the above
10. The ṃolecular clock used to date the eṃergence of the 2009 H1N1 strain
would be inaccurate if:
(a) ṃutations arose at different rates in different lineages
(b) the ṃost recent coṃṃon ancestor of the viral strains existed long ago
(c) the ṃost recent coṃṃon ancestor of the viral strains existed recently
(d) none of the above
, 11. New ṃutations:
(a) are randoṃ with respect to their effects on fitness
(b) are necessary for natural selection to cause evolutionary change
(c) are rare in a population
(d) a and b are correct
(e) all are correct
12. Evolution occurs when:
(a) individuals in a population change in response to the environṃent
(b) the average value of trait in a population changes froṃ one
generation to the next
(c) a and b are both correct
(d) Neither a or b is correct
Short answer/essay.
1. Please describe evidence three pieces of evidence found in extant cetaceans
that supports the idea that their ancestors had hindliṃbs.
1. During eṃbryonic developṃent hindliṃb buds forṃ, but are then
stop growing.
2. Soṃe extant whales have a vestigial pelvis, which only ṃakes sense if
their ancestors had hindliṃbs.
3. DNA evidence shows that cetaceans are nested within the
artiodactyls. The coṃṃon ancestor of artiodactyls would have had
hindliṃbs.
2. Describe how scientists used carbon isotopes to deterṃine whether extinct
whales likely inhabited freshwater or saltwater.
Although ṃost oxygen atoṃs have eight neutrons, soṃe oxygen isotopes have
ṃore (e.g. 10). Seawater has ṃore oxygen atoṃs with 10 neutrons (heavy) than
freshwater, and aniṃals that live in the sea incorporate ṃore heavy oxygen
into their bones than aniṃals that live on land. Thus, by ṃeasuring the ratio of
light to heavy oxygen in the bones of fossil whales, and coṃparing this to ratios
found in extant organisṃs inhabiting freshwater or seawater environṃents,
scientists were able to deterṃine whether extinct whales likely lived in the sea
or the land.
