Question
Define Evolution
Answer
The genetic changes in
a species over time.
Question
State the difference between
gradualism and
punctuated equilibrium
Answer
Gradualism - evolution over millions of
years
PE - rapid evolution over 100 to 1000
years
Question
What are three reasons
for a population of a
species to evolve?
Answer
1.
Environment
2.
Food
3.
Predator
Question
Who contributed the most to
the modern theory of
evolution?
Answer
Charles Darwin
Question
The four main ways we
can support the theory of
evolution are:
Answer
1.
Fossils
2.
Embryology
3.
Biochemistry/genetics
4.
Comparative anatomy
Question
Define the theory of
natural selection.
Answer
Organisms that are better adapted to
their environment are “selected” to be
able to survive and reproduce, passing
on their favorable traits to their
offspring.
Question
What were Lamarck’s
two main points in his
theory of evolution?
Answer
1.
2.
Use and disuse
Inheritance of acquired
characteristics
Question
Describe the idea of use
and disuse
Answer
An organism would be able to develop
a trait by using or not using it and
then that trait would be passed onto its
offspring
Question
What did Charles Darwin
not explain in his theory of
evolution?
Answer
He does not explain the
genetic basis for
variation within a
species.
Question
What is a Theory?
Answer
A theory is a statement or
model that has been tested
and confirmed many times
Question
Define Fossil
Answer
Any trace or remains of an organism
that has been preserved by natural
processes
Question
Write the fossils in order
from oldest to youngest
Answer
5,3,1,4,2
Question
Homologous or analogous
structure?
Answer
Homologous
Question
What are vestigial
structures?
Answer
Vestigial structures are structures
that are in an organism but have
reduced in size and serve little or not
function
Question
How can we use embryology
to find which organisms
have a similar ancestor?
Answer
Embryology compares the
early stages of development of
different species to find
similarities
Question
Darwin stated that
evolution was driven
by ______ ________.
Answer
Saturated
Natural selection
Monounsaturated
Polyunsaturated
Trans Fat
Question
List the six points of
Charles Darwin’s theory
of evolution?
Answer
1.
Competition
2.
Overpopulation
3.
Speciation
4.
Variations
5.
Adaptations
6.
Natural Selection
Question
Define speciation and
what is one way that
it could happen?
Answer
The formation of a new species.
One way this could happen is because
of geographic isolation
Question
Does Charles Darwin
support gradualism
or punctuated
equilibrium?
Answer
Gradualism
Question
Charles Darwin
shares his birthday
with what American
President?
Answer
Abraham Lincoln
Question
Question
During what Era did the
dinosaurs live?
Answer
The Mesozoic Era
Question
More than 99% of all
species that have lived
are now extinct.
(True or False)
Answer
True!
Question
What are 4 major eras?
Answer
1.
2.
3.
4.
Precambrian
Paleozoic
Mesozoic
Cenozoic
Question
What are three ways that
a mass extinction can
occur?
Answer
1.
Climate Change
2.
Massive volcanic eruptions
3.
Impact of a huge meteorite
Question
How is it possible that
humans (mammals)
became the dominate
species during the
Cenozoic Era
Answer
After the Mesozoic Era many
of the reptiles became extinct
and some mammals survived.
The mammals that survived
were able to evolve!
Question
Define Punctuated
Equilibrium
Answer
States that a species stays the same
for extended periods of time and
then over a hundred years a rapid
change occurs.
Question
Define what an allele is.
Answer
An allele is a trait.
(A form of a specific gene)
Question
What is convergent evolution?
Answer
Convergent evolution is when
different species become similar due
to the environmental pressures.
Question
What would cause the allele
frequencies to change in a
gene pool?
Answer
A favorable trait would
cause an allele frequency
to change over many
generations
Question
What are the four ways that
new traits are introduced to
a gene pool?
Answer
1.
Mutation
2.
Genetic Recombination
3.
Genetic Drift
4.
Migration

BETWEEN 1-10 POINTS
Final Question
Hardy-Weinberg’s Law states
that a population would not
evolve if 5 things occurred.
What are those five things?
Final Answer
1.
2.
3.
4.
5.
No mutations
No gene flow can occur (No Migration)
Random mating must occur
The population must be large enough so that no genetic drift
can cause the allele frequencies to change.
No selection can occur so that certain alleles are not selected
for, or against.
