- What is natural selection? How was it derived from artificial selection
- What are the implications of natural selection (hint: see discussion in the Stein and Rowe text on directional natural selection and watch closely Dawkins’s discussion just after Falwell makes his Watchmaker metaphor in Origins of Species.
- Give examples of natural selection (hint: Darwin’s finches on the Galápagos Islands; look for that discussion in the Stein and Rowe. text. How did the 1977 study by the Grants test that theory regarding finches on Daphne Major? What did they find out in a later study in 1982?
- What is the other side of the equation of natural selection that Darwin could not have conceived of, given knowledge at the time? In other words, what is the real origin of species? Describe the mechanisms of this process, based on your readings of .genetics and mutation. Look it up in the Stein and Rowe. text and in the Power Point lectures.
- Why is mutation often regarded as a genetic error?
- On the creationist/intelligence design issue, what arguments of the evolutionary model would the advocates of ID have to address? see instances in the Stein and Rowe. text.)
- Learn the basics of cell structure, mitosis and meiosis, replication and mutation, and translation and transcription and explain how the tie into the evolutionary process. You may look these up in your text or in You Tube (15 points)
- What roles do gene flow and genetic drift play in evolutionary change? Again, you may look these up in your text or You Tube

What is natural selection? How was it derived from artificial selection?
Natural selection can be defined as the theory defined and proposed by Charles Darwin
regarding matters to do with evolution, and it works in such a way as a process that has
organisms with traits that are heritable being favored for survival and reproduction. These traits
then leave the organisms with more offspring compared to others with an increase in frequency
over generations. Artificial selection is described as the conscious intention of humans to select
features in particular in organisms which then improves their traits. Natural selection applies to
all organisms, which is inclusive of humans. Survival is of the fittest in this case based on the
ability of these organisms to survive in nature depending on the traits they have. Derivation of
natural selection from artificial selection occurred where humans can control the passing on of
specific traits between organisms while natural selection will be dependent on the possible traits
for survival (Stein & Rowe, 1993). Humans pick on desirable features to be passed on to
organisms in artificial selection which then leads to evolutionary change which is then
comparable to natural selection regarding favoring certain traits for the survival of organisms in
their desirable aspects.
What are the implications of natural selection (hint: see discussion in the Stein and Rowe
text on natural directional selection and watch Dawkins's discussion closely just after
Falwell makes his Watchmaker metaphor in Origins of Species.
About the implication of natural selection focusing on Dawkin's discussion after the
Watchmaker metaphor, natural selection can be said to be borrowed from the belief in God being
the designer of the universe. This is with reference to the world existing from everything
working together despite the sorrows that might accompany life. As much as other authors
believed in God is the designer of the universe, Dar...
