Life Sciences Evolution Exam Guide

Acme Guide: Evolution exam

 

Theories  
Cell Theory What are the key points regarding this theory?

Why is a cell a fundamental unit of life?

Abiogenesis In this theory, where did new species come from?
Evolution  
  How is “fixity of species” related to theory of evolution?

Why does sexual reproduction contribute to diversity of species?

What is the most reliable method to dating the earth’s age?

When is a population considered adapted to minor environmental fluctuations (changes).

How is an inherited variation related to the environment?

What are two examples of the rate of change in evolution?

What are four definitions of evolution and why?

(consider process, theory, change in gene pool and diversity in species)

How is structure and function related homologous, analogous and vestigial structures?

What are four forms of indirect evidence? Provide an example.

What are three reasons why fossils may create some confusion in regards to creating a phylogenic tree.

Lamarck Did the organism change to the environment or did the environment change the organism in Lamarck’s theory and law?

What was his theory?

What was his law?

What are some examples of his theory and law?

What is an example of “an acquired characteristic”

Darwin  
  What are Darwin’s six specific points?

How did Darwin link “natural selection” to “artificial selection”?

Why is struggle for existence linked to Malthus

Why is Wallace linked to “survival of fittest”?

In both Lamarck’s and Darwin’s theories, is the source of genetic variability discussed? Why not?

Darwin’s ideas was based upon overpopulation and survival of the fittest, why?

   
Evolution in action In the case study of English Peppered Moths, what is the source for change in colour of the moth?

In the case study on amino acids and insects, how is biochemical indirect evidence linked to “degree of relatedness”?

  In the case study with mosquitos and DDT, some mosquitos developed resistance to DDT. How would Lamarck and Darwin explain this?
  If an animal “develops” a trait to catch prey, is this a proof of an acquired characteristic?
  Lamarck states some animals “develop” an acquired characteristic vs Darwin says “nature selects”. What is the difference in the role of environment on the organism for these two theories?
  In the case study of horses, what type of selection and rate of evolution is occurring?

In the “Barbellus” lab, how is geological evidence linked to phylogenetic trees?

Definitions  
  If an organism does not have “genetic potential” to adapt then the species becomes what?

What does the term “assurance” mean?

What does “fundamental” mean?

What does “fluctuate” mean?

  What is directional selection? Example

 

  What is stabilizing selection? Example
  What is disruptive selection? Example
  What is an example of evidence that is not indirect evidence?
  What is the difference between convergence and coevolution?
  What is “speciation” and how is it linked to isolation mechanisms?

 

  How is speciation linked to adaptive radiation?
  How is adaptive radiation linked to divergence of a species?
  In an interbreeding population of organisms, what is a fertile offspring called?

If two species interbreed and create nonfertile species, what are they called?

  If someone visited the Hawaiian Islands and noticed 10 species of butterflies while going from island to island, how could they explain the diversity of species by looking at Darwin’s evidence in the Galapagos Islands? What would be the role of isolation mechanisms, adaptive radiation, overpopulation, fitness of species and types of selections such as disruptive, stabilizing and directional selection.
