QUESTIONS
1.
How does a natural classification system differ from an artificial classification system? Which is the
best?
2.
Why does a taxonomist need an in depth understanding of biological evolution?
3.
In what way would it be helpful for a taxonomist to compare the amino acid sequences or triplet
sequences in DNA of various organisms?
4.
List types of criteria that are used to classify organisms. Include in your answer a discussion of
homology and analogy.
5.
Describe the Linnean system of classification.
6.
Name the five Kingdoms, give examples and list the characteristics of each.
7.
A new classification category above the kingdom(the Domain) has been proposed and is gaining
acceptance. What are the three domains? What are their characteristics?
