Key point #1 Correct answer. Even the most desperate organisms share some features, suggesting
that

the single, nine random process generated diversity.

True or False #1: biodiversity on earth will likely decrease in the near future. Correct answer.
True! Fingerprints of human activity, spread of an invasive species, Rapid change and global
climate, habitat destruction, Deforestation

What are three Worlds Views? Correct answer. 1. Natural Evolution - Evolution by natural
process

2. Theistic Evolution - Evolution guided by God

3. Creation - Species created by God

True or False #2: Human beings, as we know them, developed from earlier species of animals.
Correct answer. USA responded with 40 % true

True or False #3: Scientists believe in Evolution even though they currently lack evidence for the
theory. Correct answer. False! Based on know mechanisms: Natural Selection, Mutation, and
Genetic Drift

Key Point #2 Correct answer. Biologists accept evolutionary theory because its predictions match
observations.

True or False #4: Extreme temperatures of 2015 are sufficient evidence to conclude that Earth is
warming. Correct answer. False! Not enough data to show trend.

Single Temperature Correct answer. Datum

Normal Temperature Correct answer. Mean (Average)

Temperature Anomaly Correct answer. Deviation

Mean Anomaly Correct answer. Standard Deviation

Key Point #3 Correct answer. When something varies over space and time, one must compare
sufficient samples to quantify effects accurately.

True or False #4: When calculating a normal temperature, one should include as many years as
possible. Correct answer. False! Climatologists tend to use a thirty year period.

,What does Replicating Observations do? Correct answer. Increases reliability of patterns

What does Control Conditions do? Correct answer. Isolates effects of certain factors

What does Random Subjects do? Correct answer. Decreases bias from uncontrolled factors

What is Creationism and Catastrophism? Correct answer. All species created in six days, Earth is
6,000 years old, species fixed, extinctions from catastrophe. Leading Biologist/ Paleontologist
who championed this science/theory/belief Georges Cuvier (1769-1832).

True or False #5: Darwin's worldview when leaving England would best be described as
Creationism. Correct answer. True! He was originally trying to become a doctor then clergyman
then he finally became a Naturalist and joined Captain Fitzroy on the H. M. S. Beagle.

What did Charles Lyell contribute to science in the context of Darwinian Evolution? Correct
answer. Charles Lyell (1797-1875) believed in the old earth ideologies and slow and gradual
change. (Old Earth theory - billions and billions of years old)

What do Charles Darwin, Charles Lyell, and Alfred Wallace have in common? Correct answer.
Wallace came to same "Natural Selection" idea at similar time as Darwin did. Lyell read from
Wallace's Report and Darwin's report

Key Point # 4 Correct answer. Darwin abandoned a theory of Creationism for a theory of
evolution that better explained his observations about life.

True or False #6: Darwin could not have proposed natural selection without abandoning the idea
of creation. Correct answer. False!

What book did Darwin write? Correct answer. The Origin of Species

Phenotypes Correct answer. The trait that we see (look for def in book)

True or False #7: Natural Selection occurs whenever some individuals reproduce more than
others. Correct answer. False! Not the only element that you need. The offspring has to be similar
to parents (heritable).

What are the necessary conditions of Natural Selection? Check the accuracy of this. Correct
answer. 1. Heritable Variation

2. Differences in Reproduction

Key Point #5 Correct answer. Natural Selection occurs whenever heritable phenotypes cause
some individuals to reproduce more than others.

True or False #8: Organisms evolve by natural selection. Correct answer. False! Not organism but
the population. Populations evolve not single organism.

What did Darwin breed to display artificial selection? Correct answer. Darwin breed a variety of
pigeons and the variety was created by artificial selection.

, True or False #8: Artificial selection requires heritable variation in a trait. Correct answer. True!

Key Point #6 Correct answer. Artificial Selection confirms the potential for populations to evolve
through natural selection.

True or False #9: Populations stopped evolving after twenty-five generations, likely because no
genetic variation in lethal temperature remained. Correct answer. True! Traits can't evolve forever.
(Verify the validity of this explanation)

What are the two ingredients are necessary for Natural Selection? Correct answer. 1. Phenotypic
Selection - Some phenotypes reproduce more than others.

2. Genetic Response - these phenotypes are at least partially heritable.

True or False #9: According to the model of Blending Inheritance, a mom with Red eyes and a
Dad with white eyes would produce a mixture of offspring: some with red eyes and some with
white eyes. Correct answer. False! We wouldn't get red and white but a blend of the two colors
according to the blending inheritance theory.

Key Point # 7 Correct answer. Biologists were wary to embrace Darwin's Theory, because it
seemed to conflict with evidence.

What did Hugo de Vries (1848-1935) contribute to science in the context of Darwinian Evolution?
Correct answer. Hugo de Vries brought up the idea of mutation. New genes could pop-up from
mutations to provide the necessary genetic variation for Natural Selection.

What would blending inheritance lead to? Correct answer. Blending Inheritance would lead to a
decrease in genetic diversity/variation. (Not a realistic theory for what is really occurring)

True or False #10: According to the theory of blending inheritance, a mating between a plant that
produces round peas and a plant that produces wrinkled peas would result in offspring that
produces slightly wrinkled peas. Correct answer. True! In concordance with the theory of
Blending Inheritance.

Key Point #8 Correct answer. Genetic Variation depends on particles that segregate but do not
blend during reproduction. (Something is passing on that can come back; some kind of trait.
Recessive Gene)

What model did Gregor Johann Mendel (1822-1884) to visualize and represent genotypes and
phenotypes? Correct answer. Punnet Square! (Capital Letter reps Dominant Allele; Lower Case
Letter reps Recessive Allele)

True or False #11: If some plants with round peas were heterozygotes (Aa), then these plants
should produce offspring with wrinkled peas when mated to plants with wrinkled peas (aa).
Correct answer. True! (Aa X aa = 2 Aa and 2 aa)

Mendel is a Math Genius Correct answer. Mendel using Mathematics and logical reasoning
provided a very provided a very powerful model for not just understanding why traits can be
