Evolution Retake Prep
1) I can restate Darwin’s Postulates for Natural Selection
1. Restate Darwin’s four postulates for natural selection.
2. Although never stated by Darwin, what is his theory sometimes called?
3. Restate Darwin’s theory of natural selection.
4. Organisms that are best adapted to their environment will be most likely to:
5. How are new genes introduced into the environment?
6. Describe how lizards with the ability to jump higher and catch flying insects would come about from a
genetic and phenotypic standpoint.
7. Explain why a population of or squirrels would look different on either side of a desert if they both share a
common ancestor?
2)I can provide an accurate definition for evolution (11 points)
1. Define evolution.
2. Natural selection acts on ____________ while evolution acts on ____________ .
3. Give three examples of species that humans have modified through artificial selection.
4. What is the main mechanism for evolution or how do variations in populations come about?
The organism Pakicetus is the common ancestor for both
hippopotami and whales. It lived along shorelines and
was largely carnivorous.
Pakicetus
5. Explain how a population of organisms
diverged from Pakicetus and became a population
of whales. Please reference two anatomical features in your
description.
6. What would happen to the population if the climate grew
very cold?
7. Explain why tuberculosis and many other bacterial diseases
are becoming harder to cure.
8. In regards to artificial selection, describe the diagram at
right. Account for similarities and differences.
3) I can describe evidence for evolution including: fossils, homologous structures, embryology, and genetics/molecular
biology. (10 points)
1. How do paleontologists use fossils to explain evolution?
2. What is a homologous structure? Give one example.
3. What is an analogous structure? Give one example.
4. How would you describe embryos of different organisms very early in development?
5. What does it mean to say “there is biochemical evidence for evolution”?
6. All living organisms on Earth have the same type of DNA, but in different amounts.
a. True
b. False
4) I can explain a species distribution using natural selection theory.
5) I can map speciation and establish evolutionary relationships given fossil evidence. (10 points)
1. What event allowed mammals to evolve?
2. What is the difference between natural selection and artificial selection?
3. Give an example of a population in the wild evolving due to natural selection.
4. Reproductive isolation is a pattern of evolution that occurs when two populations _____ interbreed with
each other.
a. can
b. want to
c. start to
d. cannot
5. Explain why the statement “humans came from monkeys,” does not properly explain the theory of
evolution.
6. Create a scenario where two organisms living in the same place at the same time might diverge into two
distinct species.
