Directions: Read the worksheet below and answer the questions!
1

The scientific name for humans is Homo sapiens. What genus are humans in?

2

Why do you think that Linnaeus based his system of classification on physical simililarites alone, as opposed to utilizing molecular and genetic similarities? (think about when this was all happening)

3

Carolus Linnaeus developed a scientific naming system that is still used today. Fill in the flow chart with details about Linnaean taxonomy.

2

Why are physical similarities among species NOT always the result of being closely related?

1

Create your own mneumonic!

8

How are the levels of Linnaeus’ classification system organized? List them below. (include domain in this list)

4

Contrast the two domains Bacteria and Archaea and describe their key differences.

1

Which cell structure distinguishes members of domain Eukarya from other organisms?

2

Woese’s evidence lead him to change Linnaeaus’ 6 kingdom scheme to one with 3 overarching domains, followed by 6 kingdoms. The chart above show the 4 Kingdoms of Eukarya. Describe his rationale behind it.

4

Matching. Match the name of the kingdom on the left with the correct description on the right. Write or type the correct line next to the correct term.

Introduction: Keys are tools that provide a systematic (step-by-step) way to identify plants and animals. A series of choices are made based on the organism's characteristics to discover its identity. This fish key is based on body shape and physical features. It is a nontraditional key that is designed to help you identify a few of the fish that you may find in the aquatic habitats of Hard Bargain Farm Environmental Center.

Directions: Click on a numbered circle in the picture below to begin classifying that fish. This activity is completed when you have identified all 10 fish in the habitat.
