Unit Title: Linnaeus’ Legacy – How we arrange the diversity of Life
Purpose/Rationale: In studying biology, the diversity of life can be overwhelming. This
challenges the ability to recognize the underlying similarities between species. It is important to
be able to recognize the key characteristics that species share or differ from one another.
Understanding taxonomy and classification aids in understanding the environmental and
physiological factors that influence which traits develop. This helps us understand why life turned
out this way.

I. Perform a search to find sites that list the complete taxonomy for species. You may choose to use either of
the sites listed below:
www.plantkingdom.com/magnphyt.htm
http://www.tolweb.org/tree/home.pages/popular.html
Each column represents a taxonomic group
First column is Domain, second is kingdom, etc
II. Choose two organism and list the complete classification for those two organisms. You should choose
distinct organism. This means that they should be no closer related than order level. List this information
below.
III. What kinds of traits would you expect to find on your organism according to this information. If you
need help interpreting this information be sure to speak with me with enough time to hand in the project on
time!
(depends on chosen organism. Can describe locomotion, eating habits, type of reproduction, etc)
Note: There are millions of organisms on this planet. You have two days to locate a site and describe some
characteristics. This means that you should not have the same organism as your friends!! Choose a unique
organism!

Period:
There are three sections to this exam: multiple choice, definitions and short answer. Record all your responses on the answer key
provided as well as the number on your test, only answers placed there will be graded. You will be graded according to the test you
describe as taking (by indicating the number). The total number of points for the test is 85. Once your exam has been graded, you
will need to submit your explanation for the correct response on any question you did not receive full credit on in order. Your
explanations will be graded out of 15 points.
I. Multiple choice: 2 points each.
1. In the early stages of development, the embryos of birds and reptiles resemble each other in many ways. This
resemblance suggests that they
(1) belong to the same species
(2) are adapted for life in the same habitat
(3) share a common ancestry
(4) are both animal-like protest
2. According to Darwin’s theory of evolution, differences between species may result from
(1) the disuse of body structures
(2) the transmission of acquired characteristics
(3) natural selection
(4) mutagenic agents
3. The concept that new varietites of organisms are still evolving is best supported by the
(1) increasing need for new antibiotics
(2) increasing number of individuals in the human population
(3) decreasing number of new fossils in undisturbed rock layers
(4) decreasing activity of photosynthetic organisms due to warming of the atmosphere
The evolutionary pathway of seven living species are shown in the diagrams below:

4. Which two species are likely to have the most similar DNA base sequences?
(1) B and G
(2) E and G
(3) B and C
(4) C and D

5. Even though the finches on the various Galapagos Islands require different biotic and abiotic factors for their
survival, these finches would most likely be grouped in the same
(1) species, but found in different habitats
(2) kingdom but found in different ecological niches
(3) species and found in the same biosphere
(4) population but found in different ecosystems
6. The presence of some similar structures in all vertebrates suggests that these vertebrates
(1) all develop at the same rate
(2) evolved from different animals that appeared on Earth at the same time
(3) all develop internally and rely on nutrients supplied by the mother
(4) may have an evolutionary relationship
7. Linnaeus provided the modern synthesis of classification with his consistent application f a system of
(1) binomial nomenclature
(2) cladistics
(3) phylogenetic systematics
(4) natural selection
8. Which of the following would be a statement most likely supported by Lamark?
(1) four out of five hyena pups die because of a lack of resources in the environment
(2) the occurrence of new forms is a random event produced by a change in heritable factors
(3) the wings of a butterfly and the wings of a bat are analogous structures
(4) the long neck of a giraffe is a result of its ancestors continually trying to reach higher branches
9. A phylogenetic tree provides all of the following information except
(1) the time of divergence between
(2) a framework with which to classify organisms
(3) a hypothesis of whether similar characteristics have a common origin (homologous) or are convergent
(analagous)
(4) the evolutionary relationship among the taxa is unclear
10. Imagine taxonomic classification is like a living tree. If “kingdom” is represented by the “trunk”, what are the
large branches coming off the trunk?
(1) class
(2) order
(3) family
(4) phylum
11. In scientific names, the genus is never:
(1) lower case
(2) italicized
(3) abbreviated
(4) underlined
23
II. Definitions: 6 points each
1. Classification: a technique by which scientists sort, group and name organisms for easier study.
2. Speciation: the process by which new species are thought to arise from previously existing species.
3. Species: a biological grouping of organisms so closely related that they are capable of interbreeding and
producing fertile offspring
III. Short Answer: 9 points each
1. Imagine you’re a scientist returning from an expedition in the Sargasso Sea with a peculiar organism that is
apparently unknown to science. How can you begin to classify the organism? Describe the steps you will take
(step-by-step).
Need to list the characteristics the organism has. Have to compare to other organism and determine what it
has in common with other to place into each piece of classification scheme.
2. Arrange the following from more to less specific:
genus
family
species
species
genus
family
kingdom
kingdom
Explain why some organisms can be placed together is some of these categories but not all. (What makes each
unique? How does this reflect their evolutionary history?)
The more specific the classification the more traits in common and the more closely related the organisms
are to each other.
3. What problems could arise if a phenetics and a cladist were to design a key together? What (vocabulary) words
are important to each?
P – equal weight to all characteristics, group by similar characteristics
C – only meaningful characteristics due to evolutionary history (shared derived
characteristic)
They can disagree on what characteristics are meaningful.
4. Define binominal nomenclature. What two segments of hierarchical classification does it include? Why is it
better than using common names?
2 name naming system. Genus Species. Eliminates confusion since common names can vary by region.
5. Why is it incorrect to refer to organisms as being primitive or lower in phylogenetic trees?
Implies the other animal is advanced or higher but both have spent the same about of time evolving
