BIO 202 FINAL EXAM 2024 WITH 100% CORRECT
VERIFIED ANSWERS.
1. Which of the below statements is false
A. Only the fossil record offered support for evolution
B. Evolutionary change is the result of natural selection
C. Evolution can be documented in the fossil record
D. Populations evolve, no individuals
E. The fossil record confirms that natural selection as the determining factor in
evolution: A. Only the fossil record offers support for evolution
2. What conditions did biologist conclude were responsible for evolution of the
shape of beaks of the various species of finches on the Galapagos Island?:
Limiting food resources forced exploitation of few resources leading to beak
evolution
3. The smallest capable unit of evolution is: a population
4. Analogous structures, such as the fins on fish and whales are most often
associated with which type of evolution?: Convergent
5. Mammals and placentals evolved separately on different continents, yet they
have developed similar phenotypes under small selective pressures. This is an
example of.....: Convergence
6. The sharp reduction of the gene pool and the numbers of population surviving
through a severe epidemic is an example of...: The bottleneck effect
7. Speciation due to a behavioral change in one segment of the population in the
same locale is called: sympatric speciation
8. The evolution of different forms from the same lineage when exposed to
different selective pressures is called: divergence?
9. A subspecies is defined as a group or population of individuals of a species that
displays geographical variation. In areas where subspecies come in contact with
each other, intermediate or intergrade forms may arise. These intermediate
forms come about by: gene flow
10. Which of the following is the name of the ship on which his famous voyage took
place: HMS Beagle
11. Artificial selection is different from natural selection because: individuals are
actively bred for desired traits with no regard for natural selection
, 12. In a population of seed cracker finches, individuals have either large bills or
small bills because of types of seeds they feed on. This is an example of:
disruptive selection
13. The fusiform shape seen in fast swimming predators of different lineages in an
example of...: convergent evolution
14. Which of these is NOT an example of pre-zygotic isolation
A. Mechanical isolation
B. Temporal isolation
C. Behavioral Isolation
D. Ecological Isolation
E. Hybrid Inviability: hybrid inviability
15. Generation of new species from a progenitor population requires what event:
Reproductive Isolation
16. Random changes in allele frequencies of small populations is known as: genetic
drift
17. A drastic reduction in species diversity that is followed by a radiation of new,
unique species: punctuated equilibrium
18. DNA sequences in many human genes are very similar to the sequences of
corresponding genes in chimpanzees. The most likely explanation for this is:
humans and chimps share a relatively recent common ancestor
19. Reproductive isolating mechanisms
A. Prevent interbreeding between different species
B. Prevent gene flow
C. Reinforce genetic divergence
D. all of the above
E. none of the above: all of the above
20. Stabilizing Selection: favors intermediate forms of a trait
21. Several species of sea urchins may inhabit the same tide pool and their
reproductive periods overlap. Although they practice external fertilization, they
seldom interbreed because eggs produce chemicals that are only attractive to
sperm of their own species. This is an example of a __________ barrier
involving __________: prezygotic, gametic isolation
22. Which of the following is the correct definition of gene flow: The transfer of
alleles into or out of a population by movement of individuals
