What planet is
Chewbacca from?
Kashyyk
• Back to Board
Who did the voice for
Shaggy in the original
Scooby Doo series?
Casey Kasem
Back to Board
List 2 characteristics
that help make a
population evolve
quicker
Sexual Reproduction
and a high mutation
rate
Back to Board
Would the Vegetarian Finch,
Cactus Finch, Woodpecker
Finch and Large Tree Finch all
be able to survive on an island
together? If not which ones
would be competing
No the vegetarian finch and cactus
finch may compete for food.
The woodpecker finch and large
tree finch may compete for food as
well.
• Back to Board
What did Lyell and Hutton
determine that helped
spark Darwin’s theory of
Natural Selection
Geologic Process always
staying the same, and the
environment always
changing
• Back to Board
Name 3 different
species Darwin found
on the Galapagos island
Tortoises, Finches,
Iguanas, Armadillos,
Insects.
• Back to Board
If one species of bird
reproduces in August and
another in March what kind
isolation would keep gene flow
from happening between these
species?
Temporal isolation or
Reproductive Isolation not
for geographic reasons
• Back to Board
How does punctuated
equilibrium help explain
why there have not been
many “transition” fossils
found?
There was not much
time for fossils of these
transition species to
form
• Back to Board
Were Neanderthals and
Homo erectus around at
the same time?
No they were not
Back to Board
What is wrong with
Lamarck’s Theory of
Acquired Characteristics?
An Individual cannot change
their genotype therefore the
acquired traits are not heritable
Cannot change your phenotype
that much
• Back to Board
What two new details of
Natural Selection have
been added to Darwin’s
original theory?
Traits must be genetically
heritable
and
Variation comes from changes
in genetics and is a good thing
• Back to Board
Why are there structures
within an organism that
are very small and serve
no function? What are
these referred to as?
Vestigial Structures- at one
point they served an important
function but no longer do and
have shrunk in size because of
this
• Back to Board
Why are bacteria cells
able to make human
insulin? How does this
support Evolution?
All organisms use the same DNA
and Amino Acids in their cells.
This is because a very early
common ancestor had this and
passed this trait on
• Back to Board
How does studying
early stages of an
embryo help support
evolution?
You can see many similarities
in a variety of different
organisms embryos
• Back to Board
Which one of these
fossils is the oldest?
The Fossil of organism A.
The deeper the fossil is
found within the earth the
older it is.
• Back to Board
Is the Human or the
Chimpanzee more closely
related to the Gorilla?
They are both equally
related to the gorilla
• Back to Board
True or False
Life Gets more complex
and more diverse as time
goes on?
True: Life was much simpler
and less complex when it first
started off
• Back to Board
What do homologous
structures show?
They show similarities in
structures that are not being
directly effected by Natural
Selection
• Back to Board
Two species forming
because of differences in
behaviors like courting
dances and songs is an
example of what?
Behavioral Isolation
• Back to Board
Why can disruptive
selection eventually
lead to creation of two
different Phenotypes?
Two extremely different
phenotypes will form to help
fill two extremely different
environmental factors
(Ex. seed size)
• Back to Board
What phenomena is
this an example of?
The Bottleneck Effect
• Back to Board
Random Riddle
They are triplets
• Back to Board
What effect would
geographic isolation
have on a population?
Could lead to speciation,
Gene flow will not occur
between populations and
each population may be in a
different environmental
factors.
• Back to Board
What two effects could
the founders effect
have on a population?
Lose Diversity and
Change ratio of traits
present in the
population
• Back to Board
What is Hardy
Weinberg principle?
A population’s allele
frequency should
remain constant unless
an outside factor acts
upon it.
• Back to Board
What is the number of
times each different
allele shows up in a
population?
Allelic Frequency
• Back to Board
What is selective
breeding?
The planned breeding
of individuals to bring
out a desired trait
• Back to Board
What is an allele?
A form of a phenotypic
trait located on a
specific area of a
chromosome
• Back to Board
How can Sexual
Reproduction change a
phenotype without
changing the genotype
Gene Recombination
may combine old allele
in new advantageous
way
• Back to Board
What causes Natural
Selection to occur in a
population?
The Environment
• Back to Board
Why is diversity so
important to the
survival of a species?
Increases the chances
of an advantageous
phenotype being in the
population
• Back to Board
Natural Selection can
only act upon what part
of an organism?
The phenotype of an
organism
• Back to Board
Why would an organism
that reproduces asexually
and has a low mutation
rate not have a good
survival rate?
Would not create much
genetic diversity
• Back to Board
How is the modern theory of
evolution different than
Darwin’s Theory of Evolution
Organisms with the best
inheritable genes will survive
(not just the most fit will
survive)
• Back to Board
What is the definition
of Evolution?
Change in a population
over time
• Back to Board
How do Mutations
relate to Evolution?
Changes the Genotype
which changes the
phenotype
