BIO 181 - PNCSU (final exam)
1. The idea that most speciation is gradualism.
slow and uniform is known as
2. Darwin's work on the Galapagos Inheriting acquired characteristics
Islands led him to derive all of the
following concepts, EXCEPT:
3. People who are wealthy, and only assortative
marry people who are wealthy who
have blond hair and blue eyes are
practicing a form of _____ mating.
4. To the west of Wallace's Line in biogeography
Southeast Asia are organisms re-
lated to Asiatic species. To the east
of the line, there is a mixture of
species of Asian and Australian
origin. This is an example of:
5. Northern elephant seals have re- Bottleneck Effect
duced genetic variation most like-
ly due to being hunted. Hunting
reduced their population size to as
few as 20 individuals at the end of
the 19th century. Since then, their
population has rebounded to over
30,000, but the genes still have
much less variation than the genes
in a population of Southern ele-
phant seals that were never hunt-
ed. This is an example of...
6. A phylogeny drawn in the shape of cladogenesis
the letter Y represents...
7. Sharks and humans excrete the convergent evolution
same type of excretory product.
This is an example of...
8. evolution
, Our ancestors had much biggerjaws
than we do, which helpedthem chew
a tough diet, tear apartmeat, etc.
Their teeth also woredown quickly.
Wisdom teeth (thirdmolars) grew
later in life, andhelped our ancestors
continue toeat. Today, ~35% of
people areborn without wisdom
teeth. This is an example of:
9. Two members of the initial Amish Founder Effect
migration to Pennsylvania in 1744
shared the recessive allele for El-
lis-van Creveld syndrome, which
results in a long narrow chest
and shortening of the limbs. More
Amish people have these traits
than the surrounding non-Amish
population. This is an example of...
10. Although Jean-Baptiste Lamarck's acquired
work was important in the devel-
opment of evolutionary thought,
he was wrong because he believed
that characteristics were initially
_____.
11. A population that is infinitely large not evolve
and in which mating is completely
random is mostly likely to:
12. All of the following EXCEPT which Heterozygosity
one are mechanisms / modes /
forces of evolution?
13. Evolutionary changes within a microevolution
species are most accurately re-
ferred to as:
, 14. The only source of new genetic mutations
variation (material) is / are _____ .
15. Which of these would support a Mating is random
population remaining at genetic
equilibrium / NOT evolving? (In
other words, which of these would
not cause a population to evolve?)
16. The concept that the tempo of punctuated equilibrium
evolution is marked by isolated
episodes of rapid speciation be-
tween long periods of little or no
change is known as:
17. One way species evolve is by... diversification
18. Bart Simpson believed that mice independent variable
exposed to radiowaves would be-
come extra strong, so he per- dependent variable
formed an experiment, and placed
11 mice in front of a radio for a control group
day. He compared these 11 mice
to another 11 mice that had not
been placed by the radio. Bart's
test consisted of a heavy block
of wood that blocked the mouse
food. He found that 8 out of the
11 radio-waved mice were able to
push the block away. Seven out of
the 11 other mice were able to do
the same.
Distance from radio; How near /
close to the radio the mouse were
Number of mice who pushed the
block away
Mice not exposed to the radio
