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.
