• Objective: SWBAT use classification system in order to organize living things.
• On a piece of paper…Look at the following four pictures:
1. Put the four objects into TWO groups. What would you call the groups?

Agenda• Group: Let’s Organize Random Objects!• Individual: Classify Extra-Terrestrials!• Seven Levels of Classification• What makes a species a species?
–LIGERS and TIGONS

Classifying Random Objects!• Take all the objects out of the bag• Discuss:
--what do ALL the objects have in common?--what characteristics do some objects have that
other objects do not?
• Sort the objects into FOUR DIFFERENT GROUPS!• Write down the four classification groups onto
the notecard/paper and turn it FACE DOWN on the table!

Get a piece of paper ready for:“Classification Notes”
• What is a classification scheme?• CLASSIFICATION SCHEME– each living
organism is classified using the following scheme, from broadest to most specific:
• Kingdom Phylum Class Order Family Genus Species

What is the best way to prove that 2 species are closely related?• Using DNA to prove that organisms are
related is the best way!• The more matches in DNA means that the
more the 2 species are related!Put this in your notes!Explain what two species are related!

Exit Quiz:1. Coyotes and gray wolves have a high degree of relatedness. What
explains their high degree of relatedness?
Part of the food web in Yellowstone National Park is shown below. Gray wolves were reintroduced into Yellowstone National Park in 1995. Two years later, the population of coyotes had decreased by 50%. Coyotes were found in all habitats of the park before the gray wolves were reintroduced. Now, coyotes are most often found in the hills and mountains.Coyotes and gray wolves have a high degree of relatedness. Which of these best describes why the two species are closely related?

The figure here shows the skeletal structure of a seal's flipper and a monkey's arm.
The skeletal structures of the flipper and the arm are similar, even though they have different functions. Seals use their flippers for swimming, while monkeys use their arms primarily for grasping and lifting.
A. Which of these explains why the skeletal structures of the seal's flipper and the monkey's arm are similar?
B. Seals and monkeys have a common ancestor. C. Seals and monkeys have identical DNA sequences. D. All of the same genetic mutations occurred in seals and monkeys. E. All of the same vitamins are used for bone formation in seals and
monkeys.
