Classification Assignment
This assignment is designed to introduce/review taxonomic classification of living organisms.
Use http://learn.fi.edu/tfi/units/life/classify/classify.html to answer the following:
1. Who was the scientist that developed the orderly system of classification still used today?
2. A Binomial is a two-part name. What are the two parts that make up this name?
3. Linnaeus classified organisms mostly on physical appearances. What has impacted the way life is
classified today?
4. Click on the link that says “Biological Classification.” What does the word species mean? _____
5. What is the “technical” definition of a species?
Use http://www.ric.edu/ptiskus/Six_Kingdoms/Index.htm to answer the following:
1. Name the 6 kingdoms agreed upon by most scientists. Draw a picture to represent each, and write
down 2-3 facts about each kingdom.
2. Into which kingdom(s) are bacteria placed?
3. Which kingdom could be referred to as little eukaryotic creatures swimming around in a drop
of water (contain cilia or flagella)?
4. Which one of these kingdoms do not move or contain chlorophyll and therefore
cannot make their own food.
5. Which kingdom is many celled and contains chlorophyll which enable them to
make their own food?
Use the following website to answer these questions.

6. Using the illustration, list the 8 levels of classification.
7. Identify the classification of humans from kingdom through species.
(Give the names of all the levels from kingdom through species).
8. Use a web search and identify the classification names of the Rhesus monkey from kingdom
through species.
9. How is the classification of man different than the classification of the Rhesus
Monkey you answered in question #9?
Use http://www.biology.iupui.edu/biocourses/N100/2k23domain.html to answer the following
questions:
10. Name the 3 domains of modern classification. Beside each domain, list the
kingdoms that are included.
11. How does modern classification differ from previous classification systems?
Use the website http://www.biologycorner.com/worksheets/cladogram.html#.VSfwsPnnRM0 to
answer the following questions:
12. What is a cladogram?
13. How is “Evolutionary Classification” different than what was done in the past?
14. Use the information to explain what is meant by “Derived Characters.”
15. Examine the sample cladogram, each letter on the diagram points to a derived character, or
something different (or newer) than what was seen in previous groups. Match the letter to its character.
Note: this cladogram was created for simplicity and understanding, it does not represent the established
phylogeny for insects and their relatives.
1. ______ Wings
2. ______ 6 Legs
3. ______ Segmented Body
4. ______ Double set of wings
5. ______ Cerci (abdomenal appendages)
6. ______ Crushing mouthparts
7. ______ Legs
8. ______ Curly Antennae
16. PART II - Create Your Own Cladogram
To make a cladogram, you must first look at the animals you are studying and establish characteristics that
they share and ones that are unique to each group. For the animals on the table, indicate whether the
characteristic is present or not. Based on that chart, create a cladogram like the one shown above.
Cells
Backbone Legs
Hair
Opposable Thumbs
Slug
Catfish
Frog
Tiger
Human
DRAWING OF YOUR CLADOGRAM
17. Use this link to do an interactive cladogram activity:

you have analyzed your answers, draw in the correct cladogram with derived characteristics below.
