1. Compared the human cells resulting
from mitosis, human cells resulting from
meiosis would have
a. twice as many chromosomes
b.the same number of chromosomes
c. one-half the number of chromosomes
d.one-quarter the number of chromosomes

7. There are 3 types of polar bears: one with thick coats,
one with thin coats and one with medium coats. It is fall,
soon to be winter. The temperature is dropping rapidly
and the bears must remain warm or they will freeze to
death. Many of the bears have approximately 2 cubs (baby
bears) each but due to extreme temperatures, many
mothers only have 1 cub left.
• Favorable adaptation Thick coats
• Unfavorable Adaptation Thin coats
• If speciation were to occur, which adaptation would the
species have?
Thick and medium coats
Identify The parts to Darwin’s Theory of
Natural Selection.
1.Differences among the organisms within a
species exists. variation
2.A species produces more offspring than can
actually survive. overproduction
3.Organisms will struggle with each other for
limited resources. competition
4.Overtime, a species can evolve into different
species. speciation
5.Organisms that are most fit will survive,
reproduce and pass on the trait to offspring.
Survival of the Fittest
The diagram above shows a series of bone
structures in four different species of
vertebrates. Explain how these structures
support the theory of organic evolution.
The similarity in structure suggests that
maybe these organisms evolved from a
common ancestor.
Let’s summarize…
1. Identify some sources of variation.
Sexual repro, genetic engineering, selective breeding,
mutations, migration
2. Identify the theory in which there is no
evolution for a long period of time followed by
brief periods of change.
Punctuated equilibrium
3. Identify TWO THINGS can cause a species
to become extinct?
• No variation within a species
• Major environmental change the species
cannot adapt to
4. Why are there large populations of bacteria
now resistant to antibiotics?
• A random mutation results in a small # of bacteria
being resistant.
• They survive, reproduce and pass on the resistance
to their offspring.
• Bacteria reproduce at a very fast rate leading to a
large population of resistant bacteria in a short
amount of time.

1. Identify the common
ancestor.

2. Identify species that
have become extinct.

3. Identify the species
that have not become

Which statement could best be inferred from
the information in this diagram?
(1) Evolution does not involve gradual change.
(2) Evolutionary changes can result in
extinction.
(3) Evolution begins with plants.
(4) Evolution produces organisms that all fill
the same niche.
Which population of organisms would be in
greatest danger of becoming
extinct?
(1) A population of organisms having few
variations living in a unchanging environment.
(2) A population of organisms having few
variations living in an changing environment.
(3) A population of organisms having many
variations living in a unchanging environment.
(4) A population of organisms having many
variations living in an changing environment.
The Florida panther, a member of the
cat family, has a population of fewer
than 100 individuals and has limited
genetic variation. What inference
can be made according to the
information given?
If the environment changes and the
panthers no longer have a favorable
adaptation, they could extinct.
“Evolution is the result of long
periods of stability interrupted by
geologically brief periods of
significant change.”
This concept is called:
1. gradualism
2. natural selection
3. geographic isolation
4. punctuated equilibrium
“Evolution is the result of slow and
continuous change over time.”
This concept is called:
1. gradulism
2. natural selection
3. geographic isolation
4. punctuated equilibrium
Which concept is not a part of the
theory of evolution?
(1) Present-day species developed
from earlier species.
(2) Some species die out when
environmental changes occur.
(3) Complex organisms develop from
simple organisms over time.
(4) Change occurs according to the
needs of an individual organism to
survive.
