Classification Guided Practice1. In the cladogram, what species is most primitive?

2. In the cladogram, what species is least primitive?

3. What traits does the lizard have?

4. What traits does the salamander have?

5. What is the chimp most closely related to?

6. Is the lizard more closely related to the salamander or the perch?

Check Your Understanding

1. Binomial nomenclature: ________ names

2. Naming organisms: Genus ____________________________

3. Define primitive:

4. The most primitive organisms are drawn on the (top right or bottom left) of the cladogram. (circle

one)

5. On a phylogenetic tree, closely related organisms are drawn (closer together or further apart). (circle

one)

Classification Independent Practice1. Put the taxa in order from BIGGEST to SMALLEST

Class, Family, Genus, Kingdom, Order, Phylum, Species

2. For each subquestion, decide which is a bigger group:i. Phylum or species?

ii. Kingdom or class?

iii. Order or family?

3. What is binomial nomenclature?

4. What are the formatting requirements for binomial nomenclature?

5. Use the chart below to answer all the subquestions

Classification of Three Mammals: Blue Whale, Ferret, and Domestic CatKingdom Animalia Animalia AnimaliaPhylum Chordata Chordata ChordataClass Mammalia Mammalia MammaliaOrder Cetacea Carnivora CarnivoraFamily Mysticeti Mustelidae FelidaeGenus Balenopora Mustela FelisSpecies Balenopora physalus Mustela furo Felis catusCommon Name Blue Whale Ferret Domestic cat

A. Where do the blue whale and the ferret differ from each other?

B. Where do the domestic cat and the ferret differ from each other?

C. Is the ferret more closely related to the blue whale or the domestic cat?

D. How many levels of classification do all three animals share?

Cladogram Independent Practice

Examine the sample cladogram below, 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.

Classification Homework Use the chart below to answer all the subquestions

1. Where do the house cat and the dog differ from each other?

2. Where do the wolf and the gopher differ from each other?

3. Where do the fly and the dog differ from each other?

4. Where do the house cat and the red fox differ from each other?

5. Is the dog more related to the fox of the wolf?

6. Is the fox more related to the house cat or the dog?

7. Is the gopher more related to the fly or the wolf?

8. What two animals are most closely related?

Cladogram Homework 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.
