Final Jeopardy
10 points
True or falseA vestigial structure in one
organism can be defined as a
reduced form of a functional
structure

30 points
True or false –
Darwin developed his
theory of evolution

on the HMS
Beagle
20 points
Pollinators and flowering
plants – moth and a comet
orchid – are examples of
____________.
20 points
Pollinators and flowering
plants – moth and a comet
orchid – are examples of
coevolution
30 points
Modified True or false:
Punctuated Equilibrium
and Gradualism are two
models that describe the
cause of speciation.
30 points
False, Both describe the
RATE of speciation, not
the cause
40 points
Modified true/false
Inbreeding in a population
leads to individuals that are
heterozygous for many traits
40 points
False, inbreeding leads to more
homozygous traits in individuals
50 points
Modified True/False
The Hardy-Weinberg Principle says that
evolution will not occur in a population
unless allelic frequencies are acted on by
forces that cause change
50 points
True, the Hardy-Weinberg principle
says that evolution will not occur in a
population unless allelic frequencies
are on by forces that cause change.
10 points
In terms of population
size (large or small) and
amount of mutations
(few or many) Which
combination would
provide the greatest
potential for evolution?
10 points
Having a small population
with many mutations will
provide the greatest potential for
evolutionary change.
20 points
Bird wings and insect
wings are examples of
_____________
structures
Bonus 10 points: do they
have a common
ancestor, yes or no?
20 points
Bird wings and insect wings are
examples of Analogous structures
Bonus 10 points: do they have a
common ancestor, yes or no?
NO common ancestor
30 points
Snake pelvis and human
appendix are examples
of __________ structure
30 points
Snake pelvis and human
appendix are examples
of vestigial structure
40 points
Bones of the bird wing, whale
pectoral fin and reptile forelegs are
examples of _________ structures
Bonus 10 points: Do they show a
common ancestor- Yes or no?
40 points
Bones of the bird wing, whale pectoral
fin and reptile forelegs are examples
of homologous structures
Bonus 10 points: Do they show a
common ancestor- Yes
50 points
Superficially similar features molded
by natural selection in very different
species would be classified as
__________ structures.
“Superficial” means that it only
appears to be the same from the
outside, but is totally different on the
inside
50 points
Superficially similar features molded
by natural selection in very different
species would be classified as
Analagous structures.
“Superficial” means that it only
appears to be the same from the
outside, but is totally different on the
inside
10 points
If Derived traits are
recent, then _________
traits are more primitive
10 points
If derived traits are more recent, then
ANCESTORAL traits are more primitive
20 points
If a population of
organisms is in genetic
equilibrium, then the
_____________
principle is expressed.
20 points
If a population of organisms is in
genetic equilibrium, then the
HARDY-WEINBERG
PRINCIPLE is expressed.
30 points
In general, if a population
diverges and becomes
reproductively isolated, then
__________ has occurred.
30 points
In general, if a population diverges
and becomes reproductively
isolated, then SPECIATION has
occurred
40 points
If no physical barrier
separates a diverging
population as it becomes
two distinct populations,
then _________ has
occurred.
40 points
If no physical barrier separates a
diverging population as it becomes two
distinct populations, then Sympatric
speciation has occurred.
30 Bonus points: NAME the other type of
speciation and give an example…
50 points
If a species is suddenly introduced into a
new habitat (Example: the cichlids that
once lived in Africa’s Lake Victoria) then
__________ might occur.
50 points
If a species is suddenly introduced
into a new habitat (example: the
cichlids that once lived in Africa’s Lake
Victoria) then Adaptive Radiation
might occur.
10 points
Modified True/False:
A mutation is a random
change in genetic material
10 points
TRUE, A mutation is a
random change in
genetic material
20 points
Modified True/False
Any change in the allelic
frequencies in a population
that is due to chance is called
founder effect.
20 points
FALSE
Any change in the allelic
frequencies in a
population that is due to
chance is called
Genetic drift
30 points
Modified True/False
A population of ants declines to a very
low number. When the ants’ habitat is
turned into a park for picnics by humans,
the population of ants rebounds. This is
an example of natural selection.
30 points
False
A population of ants declines to a very low
number. When the ants’ habitat is turned
into a park for picnics by humans, the
population of ants rebounds. This is an
example of bottleneck
40 points
Modified True/False
Humans either born below-normal or abovenormal birth weights have a lower chance of
survival than those with average birth
weights. Thus, human birth weights vary
little. This is a form of natural selection
called stabilizing selection.
40 points
true, Humans either born below-normal or
above-normal birth weights have a lower
chance of survival than those with average
birth weights. Thus, human birth weights
vary little. This is a form of natural selection
called stabilizing selection.
50 points
Modified True/False
Embryos of different organisms exhibit
homologous structures during early
development, but later become totally
different structures in adult form. This
indicates that the organisms evolved from
different ancestors.
50 points
False
Embryos of different organisms exhibit
homologous structures during early
development, but later become totally
different structures in adult form. This
indicates that the organisms evolved from
common ancestors.
Final Jeopardy
Name the 5 different
mechanisms of evolution
Final Jeopardy Answer
Mechanisms of evolution include:
genetic drift (founder effect, bottleneck),
gene flow,
nonrandom mating,
mutations, and
natural selection (which would include:
stabilizing selection, disruptive selection, and
directional selection)
