Bio 124 Exam 1 Review UPDATED
ACTUAL Exam Questions and CORRECT
Answers
what does it mean for a structure to be homologous? - CORRECT ANSWER - it is the
same structure, with a different function
what are traits, small changes over a period of time, adaptation to the environment, changes in
population/community? - CORRECT ANSWER - evolution
Do individuals evolve or populations? - CORRECT ANSWER - populations
what did Darwin note about current species? - CORRECT ANSWER - that they are
descendants of ancestral species
how is evolution defined by Darwin? - CORRECT ANSWER - descent with modification
evolution is the change in the __________ ___________________ of a population from
generation to generation - CORRECT ANSWER - genetic composition
what can evolution be viewed as? - CORRECT ANSWER - a pattern and a process
what challenged traditional views of a young Earth inhabited by unchanging species? -
CORRECT ANSWER - the darwinian revolution
how did Aristotle view species? - CORRECT ANSWER - as fixed
how did Aristotle arrange species? - CORRECT ANSWER - on a scala naturae (ladder of
nature)
,who interpreted organismal adaptations as evidence that the Creator has designed each species
for a particular purpose? - CORRECT ANSWER - carolus linnaeus
what was carolus Linnaeus the founder of? - CORRECT ANSWER - taxonomy
what is the branch of biology concerned with classifying organisms? - CORRECT
ANSWER - taxonomy
what did carolus Linnaeus develop? - CORRECT ANSWER - the binomial format for
naming species (binomial nomenclature)
what helps lay the groundwork for Darwin's ideas? - CORRECT ANSWER - fossils
where are fossils found? - CORRECT ANSWER - in sedimentary rock layers or strata
what changed the ideas of evolution - CORRECT ANSWER - paleontology
the deeper the fossil is found in the strata, __________________ - CORRECT ANSWER -
the older the fossil
what does paleontology do and who developed it? - CORRECT ANSWER - creates
timeline and scale of how things changed
Georges Cuvier
what can we deduce from dramatic change in flora/faunal fossils? - CORRECT
ANSWER - major environmental change could have caused this, a new predator
introduced (change of community), or climate/physical/chemical change could have caused this
because these all change what is successful
, who said that earth's surface changing in slow continuous actions - CORRECT
ANSWER - James hutton and charles lyell
what did Lyell propose that strongly influenced Darwin's thinking? - CORRECT
ANSWER - that the mechanisms of change are constant over time
what was the prime theory of how things changed over time for a while and who hypothesized
it? - CORRECT ANSWER - - species evolve through use and disuse of body parts and the
inheritance of acquired characteristics
-lamarck
what is different between Lamarck's ideas and darwinism? - CORRECT ANSWER -
Lamarck says that there is only one species (ex. a giraffe stretches its neck overtime)
what is wrong with Lamarckism? - CORRECT ANSWER - - forgets genetic association
- says that things get more complex and the more complex the better
what is an example of how Lamarckism works - CORRECT ANSWER - the idea that
muscle tone can be passed on to offspring
what are examples of artificial selection - CORRECT ANSWER - dog breeding,
agriculture, etc.
what explains the adaptations of organisms and the unity and diversity of life? - CORRECT
ANSWER - descent with modification by natural selection
what did Darwin think about the age of the earth? - CORRECT ANSWER - thought that
earth was more than 6,000 years old
what did Darwin hypothesize about species from south america - CORRECT ANSWER -
that they had colonized the Galapagos and speciated on the islands
