Final Jeopardy
1 - $100

Scientist that believed Earth’s geologic features
formed as a result of gradual processes and
Floods, earthquakes, and glaciers of the present
do not cause great destruction of Earth’s
surfaces.

Charles Lyell
1 - $200
Said that humans tend to produce more offspring
than nature can support. Food production
increases at a slower rate than population.

Thomas Malthus
1 - $300
Believed that Nature selects those individuals w/
favorable traits to leave more offspring that are
better suited or FIT for their environment
Descent with modification occurs over time.
Each living species has descended, with changes,
from other species over time

Charles Darwin
1 - $400
The oldest fossils are found in ______ rock
 The oldest, more simple rocks are found in the
lowest or highest layer?


Sedimentary and Lowest
1 - $500

The two ways to determine the age of fossils?

Relative Dating and Radioactive Dating
2 - $100

Animals that live in similar ecological conditions
are exposed to similar pressures of natural
selection. These animals evolve different
characteristics. True or False?

False
2 - $200
Similar structures but different functions
Structures develop from same clump of embryonic
cells.

Homologous
2 - $300
Structures / organs that are reduced in size; do
not seem to serve a useful function.

Vestigial
2 - $400
Because embryos of vertebrates are very similar in
early development, the same groups of embryonic
cells develop in the same order and in similar
patterns to produce tissues and organs. This
implies they share a common ancestor. True or
False?

True
3 - $100

Adaptations being selected for increase an
individual’s fitness in the environment

Natural Selection
3 - $200


5 requirements of Natural Selection
Variation, Over-population, Struggle for
Existence, Fitness, and Adaptation over time
3 - $300

Helpful mutations lead to adaptation by
increasing fitness and decreasing the death rate.
What will happen to the frequency of the helpful
mutation?

It will increase
3 - $400

How does natural selection apply to survival of
the fittest?
The individuals that survive to reproduce more
often have variations that are best suited to the
environment (survival of the fittest). As the
environment changes, favored traits and allele
frequencies will change, causing the population to
evolve
4 - $100

Consists of all genes, including all the different
alleles that are present in a population.

Gene Pool
4 - $200

Random change in allele frequencies that occurs
in small populations and doesn’t work to
produce adaptations

Genetic Drift
4 - $300

The transfer of alleles or genes from one
population to another; also known as gene
migration.

Gene Flow
4 - $400

Members of an original species can no longer
breed together to produce fertile offspring. They
are considered 2 separate species.

Speciation
4 - $500
1)___Two populations are capable of interbreeding but
have differences in courtship rituals or other reproductive
strategies that involve behavior
2)____a barrier that physically separates members of a
species into two or
more groups.
3)____Form of reproductive isolation in which two
populations reproduce at different times
1) Behavioral
 2) Geographic
 3) Temporal

5 - $100
1. Members at one end of distribution curve have a
higher fitness than those in the middle or at the
other end of the curve.
2. This type of selection favors average individuals
and reduces variations in populations
3. When members at BOTH ends of the distribution
curve have a higher fitness than those in the
middle
Directional
2. Stabilizing
3. Disruptive
1.
5 - $200
This can lead to the evolution of two new
species.
2. Can lead to one population evolving into a new
species
3. Reduces variation in a population; evolution is
not likely to happen.
1.
Disruptive
2. Directional
3. Stabilizing
1.
5 - $300

What is the difference between gradualism and
punctuated Equilibrium?
Gradualism- Long time with gradual change
 Punctuated Equilibrium- Long, stable periods
interrupted by brief periods or more rapid
change

5 - $400

What is the difference between divergent
evolution (adaptive radiation) and convergent
evolution?
Divergent- type of evolution in which one
species evolves into two separate species
because it is adapting to different environmental
situations
 Convergent- type of evolution in which two
unrelated species evolve similar characteristics
because they are both adapting to the same
environmental situations

5 - $500

What are the conditions to maintain genetic
equilibrium?
1. There must be random mating.
2. The population must be very large. Genetic drift
has less effect on large populations than on small
ones.
3. There can be no movement into or out of the
population. Individuals may bring new alleles into
a population.
4. There can be no mutations.
5. There can be no natural selection. No
phenotype can have a selective advantage over
another.
Final Jeopardy
Imagine you’re given graphs that show the
number of flies with different phenotypes or wing
lengths. They live on an isolated island, where
flies compete with one another for food. As a
result, those flies with long wings fly 20 meters or
higher off of the ground. Those with short wings
fly less than 5 meters above the ground. Those
with intermediate wing length fly at an average of
12 meters off of the ground. Which natural
selection graph would show that the intermediate
(average) length is more successful and is the
most common length?
Stabilizing Selection
