Evolution 4 – Measuring Evolution
Due Date: ____________________
Stamp: _________________
Textbook Reading: Ch. 23 Concept 23.1
Presentation Prezi: Evolution 4: Measuring Evolution
Supplementary Resources:

Crash Course Biology
o Population Genetics – When Darwin Met Mendel: Biology #18

Bozeman’s Science: Paul Anderson:
o Hardy-Weinberg Equilibrium
Big Questions:
 How is variation generated and maintained in a population?
 How do we know evolution is happening in populations?
 What aspects of a population contribute to evolution?
 How can evolution be qualitatively and quantitatively measured?
 How does measuring evolution help us understand how populations are
evolving?
Questions to Answer:
1. Explain the meaning of the saying “individuals are selected, populations
evolve”
2. How is variation generated in a population? How is it maintained?
3. Explain the relationship between the terms alleles, genes and gene pool.
4. Explain the relationship between the terms genotype and phenotype.
5. Explain the relationship between the terms homozygous and
heterozygous.
6. How is it possible that individuals with two different genotypes can have
the same phenotype?
7. Explain how each of the following features of a (hypothetical) population
in Hardy-Weinberg.
Equilibrium leads to that population not evolving over time:
1. Large population size
2. Random mating
3. No immigration/emigration
4. No net mutation rate
5. A constant environment
8. Answer questions A-C in the “Solving HW Problems” section of this
presentation.
A.
B.
C.
9. If no real population of organisms is in Hardy-Weinberg Equilibrium, why
is it a useful tool to study the effects of evolution?
Make Sure You Can:
(feel free to ask questions about them in class)
 Explain how variation is produced and maintained in a population.
 Define all new terms used in this presentation in your own words and give
descriptive examples.
 Explain how each source of evolution in a population affects variation and
selection.
 Use the HW theorem with facility (be able to move through all terms of
both equations)
 Apply the HW theorem to actual populations
Evolution 5 – Speciation
Due Date: ____________________
Stamp: _____________________
Textbook Reading: Ch. 24
Presentation Prezi: Evolution 5: Speciation
Supplementary Resources:

Crash Course Biology
o Speciation – of Ligers & Men: Biology #15

Bozeman’s Science: Paul Anderson:
o Speciation
Big Questions:
 What is a species?
 How can evolutionary changes in a population lead to the production of
new species?
Questions to Answer:
1. Explain what the “Biological Species” definition is. Describe its
strengths and weaknesses.
2. Why does a biological species have to be reproductively isolated from
other organisms?
3. Compare allopatric and sympatric speciation.
4. What is a ring species?
5. Briefly explain the following species barriers.
1. Habitat isolation
2. Temporal isolation
3. Behavioral isolation
4. Mechanic isolation
5. Gametic isolation
6. Reduced hybrid viability
7. Reduced hybrid fertility
8. Hybrid breakdown
6. Explain why the creationist claim that speciation has never been
observed is wrong.

Apply the biological species definition, and identify circumstances where it
is not applicable.
Explain the circumstances that can lead to the production of a new
species both allopatrically and sympatrically.
Define all species barriers described in this presentation, and provide
examples of these barriers.
Compare the common models of the pace of speciation, and cite evidence
that supports both gradualism and punctuated equilibrium.
Evolution 6 – Brief History of Life
Due Date: ____________________ Stamp: _______________
Textbook Reading: Ch.26 (26.1, 26.2)
Presentation Prezi: Evolution 6: Brief History of Life
Supplementary Resources:

Crash Course Biology
o Natural Selection: Biology #14

Bozeman’s Science: Paul Anderson:
o The Origin of Life – “Scientific Evidence”
o Abiogenesis
o Speciation and Extinction
Big Questions:
 How old is the Earth? Where did it come from?
 How did life begin?
 How have the history of life and the history of Earth influenced each
other?
Questions to Answer:
1. Science is based on observations. How can we begin to scientifically
investigate events that we were not around to observe?
2. With a ruler, draw a line that is 20 cm long. Divide the line into five 4 cm
segments. On a scale of each segment representing one billion years,
label the following events in the history of earth:
1. Formation of the earth
2. Origin of life
3. Evolution of photosynthesis
4. Evolution of eukaryotes
5. Evolution of multi-cellular life
6. The Cambrian explosion
7. First vertebrate land animals
8. Evolution of dinosaurs
9. Evolution of human beings
3. Explain the hypothesis, procedure and results of the Mill-Urey
experiment.
4. Why is it hypothesized that the evolution of RNA preceded the evolution
of DNA?
5. Explain the concept of “adaptive radiation”. Why have adaptive radiations
proceeded mass extinction events?
6. Why do some folks feel that we are living through the sixth “Great
Extinction”?
7. Explain how it is possible to get large changes in an organism’s
development with only a few changes to that organism’s genome?
8. What do Homeobox genes do in animals?
