What planet is Chewbacca from?
Kashyyk

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 andVariation 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 FalseLife 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
