BIO 182 QUIZ 1 WITH COMPLETE
SOLUTIONS
Who developed palentology - Correct Answers -The study of fossils
by Cuvier
What did Lyell's perceive on the voyage of beagle - Correct Answers -adaptation
Who defined Natural Selection? what's the definition? - Correct Answers -Lyell
process in which individuals with favorable inherited rates are more likely to survive &
reproduce
What are the 3 observations of Darwin - Correct Answers -1. Unity of life 2. Diversity of
Life 3. Match of Organisms & enviornment
which evolve? populations or individuals? - Correct Answers -Natural selection acts on
individuals but only populations evolve
What causes adaptive evolution - Correct Answers -Natural selection
Microevolution - Correct Answers -change in allele freq. in a population over
generations
What is the prerequisite for evolution - Correct Answers -trait variation
Natural selection can cause what - Correct Answers -adaptive evolution (improvement
in match between organism & enviornment)
Genetic drifts reduces what - Correct Answers -genetic variation thru the loss of alleles
The smaller the sample, the greater change of random deviation from results
Difference between Founder & Bottleneck effect - Correct Answers -Founder- few
individuals become isolated
Bottleneck- SUDDEN reduction in pop size due to change in enviornment
Genetic variation - Correct Answers -caused by differences in genes or DNA segments
What is discrete character vs a quantitative character? - Correct Answers -Discrete:
single gene phenotypic diff
, Quantitative: 2+ genes phenotypic diff along population continuum
What are the 2 ways to measure genetic variation
Which cause evolutionary consequences - Correct Answers -Gene variability
Nucleotide variablitity
Genetric variability
Gene variability - Correct Answers -average % of heterozygous
Nucleotide Variability - Correct Answers -comparison of DNA sequences of pairs of
individuals
What are the 4 sources of gene variation - Correct Answers -New Alleles
Alter Gene # or position
Rapid Reproduction
Sexual Reproduction
Who viewed species as fixed and arranged them? - Correct Answers -Aristotle
Evolution is a - Correct Answers -process and pattern
Another term for evolution by Darwin - Correct Answers -descent with modification
Who is the founder of Taxonomy what else did he do - Correct Answers -Linnaeus
classify animals with binomial format
Fossils - Correct Answers -remains/traces of organisms from the past
What are the layers of fossils called and what does it tell us? - Correct Answers -Strata
that top layers are younger with more recent fossils
What is the principle of uniformitarinism
who came up with this - Correct Answers -mechanisms of change are constant over
time
Lyell & Hutton
What is Lamarck's hypothesis - Correct Answers -Evolve through "use or disuse"
What does Darwin drawing of a tree symbolize - Correct Answers -History of life is like
tree with branches
What is artificial selection? - Correct Answers -modified species by selecting/breeding
those with favorable traits
what are the 2 observations of artificial selection - Correct Answers -1. members of pop.
vary in inherited traits
