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?
Answer1. 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:
Answer1. Fossils
2. Embryology
3. Biochemistry/genetics
4. Comparative anatomy
Question
Define the theory of natural selection.
AnswerOrganisms 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. Use and disuse
2. Inheritance of acquired characteristics
Question
Describe the idea of use and disuse
AnswerAn 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?
AnswerHe does not explain the
genetic basis for variation within a
species.
Question
What is a Theory?
AnswerA theory is a statement or model that has been tested and confirmed many times
Define Fossil
Question
Any trace or remains of an organism that has been preserved by natural
processes
Answer
Write the fossils in order from oldest to youngest
Question
5,3,1,4,2
Answer
Homologous or analogous structure?
Question
Homologous
Answer
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
How can we use embryology
to find which organisms have a similar ancestor?
Question
AnswerEmbryology compares the
early stages of development of different species to find
similarities
Question
Darwin stated that evolution was driven by ______ ________.
Saturated Monounsaturated Polyunsaturated
Trans Fat
Answer
Natural selection
Question
List the six points of Charles Darwin’s theory
of evolution?
Answer1. 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
QuestionDoes Charles Darwin
support gradualism or punctuated equilibrium?
Answer
Gradualism
Question
Charles Darwin shares his birthday
with what American President?
Answer
Abraham Lincoln
Question
During what Era did the dinosaurs live?
Question
Answer
The Mesozoic Era
QuestionMore than 99% of all species that have lived
are now extinct. (True or False)
Answer
True!
Question
What are 4 major eras?
Answer1. Precambrian2. Paleozoic3. Mesozoic4. Cenozoic
Question
What are three ways that a mass extinction can
occur?
Answer1. Climate Change
2. Massive volcanic eruptions
3. Impact of a huge meteorite
QuestionHow is it possible that
humans (mammals) became the dominate
species during the Cenozoic Era
AnswerAfter 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.
AnswerAn allele is a trait.(A form of a specific gene)
QuestionWhat 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?
AnswerA 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?
Answer1. Mutation
2. Genetic Recombination
3. Genetic Drift
4. Migration
MAKE YOUR FINAL WAGE
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?
1. No mutations2. No gene flow can occur (No Migration)3. Random mating must occur4. The population must be large enough so that no genetic drift
can cause the allele frequencies to change.5. No selection can occur so that certain alleles are not selected
for, or against.
Final Answer
