***Quiz over Evolution by Natural Selection (10/27 lecture material) on TUESDAY.***
1. How do Species and Population differ?
i. Species:
Evolution by Natural
Selection
ii. Population:
2. Which is the smallest unit that can evolve; species or population?
3. What is Evolution?
4. Microevolution vs macroevolution
5. The people involved and their Proposals (word bank below)
__________ Developed the study of fossils, opposed evolution, Advocated catastrophism
_______________ Founded taxonomy, believed Creater designed each species for a specific
purpose, “for the greater glory of God”
______________ Developed a theory similar to Darwin’s… 20 years after
____________ 1st to state evolutionary change but had the wrong mechanism. Hypothesized that
species evolve through use and disuse and through the inheritance of acquired traits.
_____________ First scientist to carry out a thorough study of the living world, developed an
early classification system, established the modern concept of a species
__________ This person’s view on life was descent with modification
____________Advocated Uniformitarianism (mechanism of change are constant over time)
_________ Claimed that every organism was an example of a perfect essence, or type, created
by God
_________ Proposed that species were organized into a fixed sequence based on increasing size
and complexity
A. John Ray B. Carolus Linnaeus C. Georges Cuvier D. James Hutton/Charles Lyell
E. Jean-Baptiste de Lamark F. Charles Darwin G. Alfred Wallace H. Plato I. Aristotle

6. Would you describe Charles Darwin as an observational biologist or an experimental
biologist?
7. What island and what type of bird did Charles Darwin much of his research?
8. Darwin’s publication in 1858 was called what?
a. He did not use what term in the publication?
b. Species change through ____________
c. Species are related through descent from a common ___________
9. A hypothesis that has been tested and is well supported by data is known as?
10. What are some of the evidences of change?
11. Natural vs. Artificial Selection
12. List Darwin’s 4 postulates.
13. Fitness vs adaptation vs selection
14. Everything listed below are common ______________
 Evolutionary change occurs in organisms
 Adaptations occur because organisms want or need them
 Organisms sacrifice themselves for the good of the species
 Evolution perfects organisms
15. Darwin perceived adaptation to the environment and the origin of new species as
____________
Review
1. Recombination frequency
In a particular animal species, a long tail (T) is dominant to a short tail (t), and a blonde hair (B)
is dominant to grey hair (b). When a TtBb female is mated with a ttbb male, the observed
distribution of offspring is as follows 1000 offspring with a long tail and blonde hair, 100
offspring with a long tail and grey hair, 500 offspring with a short tail and blonde hair, and 50
offspring with a short tail and grey hair. Based on these offspring, what is the approximate
recombination frequency?
2. Which event is NOT unique to meiosis?
A. Formation of a bivalent through synapsis
B. Replication of chromosomes
C. Crossing over of nonsister chromatids through a chiasma
3. What is homology?
A. A difference that exists in species due to evolution
B. A similarity that exists in species descended from a common ancestor
C. A similarity that exists in a species because of siblings
4. Meiosis results in the formation of how many daughter cells?
A. 2
B. 3
C. 4
5. How many possible daughter cell combinations are there for an organism with a
diploid number of 8?
6. You have a cat with short fur (ff) and green eyes (Gg).
-What type of cross would you perform if this cat were to mate?
-How many different types of gametes can your cat produce, and what are they?
7. According to the biological species concept, two organisms are considered to be
different species if they
A. Look different
B. Live in different habitats
C. Are members of different populations
D. Cannot mate and produce viable, fertile offspring
8. Which of the following scientists developed a theory of evolution that was very
similar to Charles Darwin’s?
A. James Hutton
B. Alfred Wallace
C. Georges Cuvier
D. Jean-Baptiste de Lamarck
