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?”

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

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

Start of activity…Tuesday

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

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

Sorting Tree Examples..

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.

Museum of Natural History: 33 million things

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

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:

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.

Let’s look at some animals

Devil Cat

Ghost Cat

Mountain Lion

Screaming Cat

Puma

Florida Panther

Cougar

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 Confusion in Using Different Languages for Names copyright cmassengale

23 Latin Names are Understood by all Taxonomists copyright cmassengale

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 Carolus Linnaeus 1707 – th 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

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

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

BONUS: How to preserve a specimen

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

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.

32 Darling Darling Katy Katy Perry Perry Came Came Over Over For For Good Good Soup! Soup!

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

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?

Describe 2 conclusions that can be made from this information.

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?

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

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.
