Biology 182 ASU Exam 1Key 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.
