1 Today you will need: Writing utensil, Journal, New Bellwork sheet Bellwork for today: You will have homework tonight. WELCOME, MY NINJAS Write the question and answer it. “What are at least five things we classify in our world?”

2 HW: Classification Levels Search for the YouTube video “Classification Levels”Classification Levels by Alyssa Dolny. *Yes…you can expect a quiz.

3 Taxonomy Essential Question: Why is taxonomy important and helpful to scientists?

4 Start of activity…Tuesday

5 What is classification? Name some things that we classify into groups. Why do you think we (humans) classify things into groups?

6 CLASSIFICATION ACTIVITY -Online Shopping -Grocery Store (Sorting Tree) -Do It Yourself

7 Sorting Tree Examples..

8 A.Netflix B.Vehicles C.Toy Store D.Music E.TV Shows F. High School G.Sports Store Each chart must include SIX levels with at least FOUR examples per level.

9 Museum of Natural History: 33 million things

10 Classification is the grouping of objects or information based on similarities.

11 Taxonomy is the science of grouping and naming organisms. …… in other words, taxonomy is the process of classifying and naming biological (living) organisms. In Biology:

12 EVOLUTIONARY CLASSIFICATION Biologists group organisms into categories that represent lines of evolutionary descent not just physical similarities. Phylogeny: The study of evolutionary relationships among organisms.

13 Let’s look at some animals

14 Devil Cat

15 Ghost Cat

16 Mountain Lion

17 Screaming Cat

18 Puma

19 Florida Panther

20 Cougar

21 There are at least 50 common names for the animal shown on the previous 7 slides. Common names vary according to region. How could we fix this problem?

22 22 Confusion in Using Different Languages for Names copyright cmassengale

23 23 Latin Names are Understood by all Taxonomists copyright cmassengale

24 Benefits of Classifying Accurately & uniformly names organisms Prevents misnomers such as starfish & jellyfish that aren't really fish Uses same language (Latin or some Greek) for all names Sea”horse”??

25 25 Carolus Linnaeus 1707 – 1778 18th century taxonomist. Called the “Father of Taxonomy”. Classified organisms by their structure. Developed naming system known as binomial nomenclature. Two-word name (Genus and Species) copyright cmassengale

26 The genus name is written first (always Capitalized). The species name is written second (never capitalized). Both words are italicized if typed or underlined if hand written. Example: Felis concolor or F. concolor Which is the genus? The species? Binomial Nomenclature a two name system for writing scientific names. Turdus migratorius

27

28 28 Binomial Nomenclature Which TWO are more closely related? copyright cmassengale

29 BONUS: How to preserve a specimen

30 Basis for Modern Taxonomy Homologous structures (same structure, different function) Similar embryo development Molecular Similarity in DNA, RNA, or amino acid sequence of Proteins

31 Domain Kingdom Phylum Class Order Family Genus Species BROADEST TAXON Most Specific The major classification levels, from most general (broadest) to most specific A group at any level is a taxon. Multiple levels are taxa.

35 The six kingdoms in the classification system are: 1. Eubacteria 2. Archaebacteria 3. Protista 4. Fungi 5. Plantae 6. Animalia

36 Debrief 1.What characteristics do you think separate the different kingdoms? 2.What are some things you would classify in the kingdom Fungi? Eubacteria? Plantae?

37 Dichotomous Key Search for the YouTube video “ Dichotomous Key” Dichotomous Key by Mark Drollinger Complete the worksheet using the information in the video. Due TOMORROW. http://www.youtube.com/watch?v=M51AKJqx-7s

38 Walking Review (Friday)

39 OrganismCatWolfFly Kingdom Animalia Phylum Chordata Arthropoda Class Mammalia Insecta Order Carnivora Diptera Family FelidaeCanidaeMuscidae Genus FelisCanisMusca Species F. domesticusC. lupusM. domestica

40 1.What type of animal is Musca domestica? 2.From the table, which 2 animals are most closely related? 3. At what classification level does the evolutionary relationship between cats and wolves diverge (become different)?

41

42 4.What is the scientific name for the Canada goose? 5.Explain which two organisms are the most closely related. 6.Which taxa do the human and goose have in common?

43

44 7.At which taxon do the lion and lynx diverge? 8.Which kingdom does C. comatus belong to? 9.Which taxa do the lion and lynx have in common? 10. What is the scientific name for the lion?

45 African BuffaloBurchell’s ZebraGrant’s Gazelle Animalia Chordata Mammalia Artiodactyla Bovidae Synceruscaffer Animalia Chordata Mammalia Perissodactyla Equidae Equusburchellii Animalia Chordata Mammalia Artiodactyla Bovidae Nangergranti 11. Describe 2 conclusions that can be made from this information.

46 The mushroom sea squirt is in the same class as the common sea grape. The mushroom sea squirt is in the same family as the blue spot ascidian. The mushroom sea squirt is in the same order as the white speck tunicate. The mushroom sea squirt is in the same phylum as the starry skate. The information below describes the most specific levels of classification that the mushroom sea squirt, Sycozoa gaimardi, shares with four other organisms. 12. To which of the four organisms is the mushroom sea squirt most closely related?

47 13. Which of the beetles above must belong to the same family?

48 14. Four students researched the classifications of the following eight whales: killer whale, Orcinus orca gray whale, Eschrichtius robustus humpback whale, Megaptera novaeangliae pygmy right whale, Caperea marginata fin whale, Balaenoptera physalus minke whale, Balaenoptera acutorostrata North Atlantic right whale, Eubalaena glacialis bowhead whale, Balaena mysticetus The students were asked which two whales are most closely related and why. The table below summarizes the students’ answers. Based on the classifications, which student gave the correct answer to the question? StudentWhales Most Closely Related Reason 1killer whale and gray whale They are both mammals. 2humpback whale and pygmy right whale They are both whales. 3fin whale and minke whale They are both in the same genus. 4North Atlantic right whale and bowhead whale They are both in the same family.
