Biology 182 ASU Exam 1/207 AccurateQuestions & Solutions
Key point #1 - -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. - -True! Fingerprints of human activity, spread of an invasive species,
Rapid change and global climate, habitat destruction, Deforestation
-What are three Worlds Views? - -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. - -USA responded with 40 % true
-True or False #3: Scientists believe in Evolution even though they currently
lack evidence for the theory. - -False! Based on know mechanisms: Natural
Selection, Mutation, and Genetic Drift
-Key Point #2 - -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. - -False! Not enough data to show trend.
-Single Temperature - -Datum
-Normal Temperature - -Mean (Average)
-Temperature Anomaly - -Deviation
-Mean Anomaly - -Standard Deviation
-Key Point #3 - -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. - -False! Climatologists tend to use a
thirty year period.
,-What does Replicating Observations do? - -Increases reliability of patterns
-What does Control Conditions do? - -Isolates effects of certain factors
-What does Random Subjects do? - -Decreases bias from uncontrolled
factors
-What is Creationism and Catastrophism? - -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. - -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? - -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? - -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 - -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. - -False!
-What book did Darwin write? - -The Origin of Species
-Phenotypes - -The trait that we see (look for def in book)
-True or False #7: Natural Selection occurs whenever some individuals
reproduce more than others. - -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. - -1. Heritable Variation
2. Differences in Reproduction
-Key Point #5 - -Natural Selection occurs whenever heritable phenotypes
cause some individuals to reproduce more than others.
, -True or False #8: Organisms evolve by natural selection. - -False! Not
organism but the population. Populations evolve not single organism.
-What did Darwin breed to display artificial selection? - -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. -
-True!
-Key Point #6 - -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. - -True! Traits can't evolve forever. (Verify the validity of this
explanation)
-What are the two ingredients are necessary for Natural Selection? - -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. - -False! We
wouldn't get red and white but a blend of the two colors according to the
blending inheritance theory.
-Key Point # 7 - -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? - -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? - -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. -
-True! In concordance with the theory of Blending Inheritance.
