3. Joke of the Day: A set of Jumper Cables goes into the bar… Bartender says… “I will serve you but you had better not start anything!!!”

4. Quiz Alert Who? YOU! When? Next Class What?

5. Unit 6:Classification of Living Things

6. All Living Things… Are classified by certain characteristics Are put into categories based on similarities and relationships to other living things Have a certain DOMAIN, KINGDOM, PHYLUM, CLASS, ORDER, FAMILY, GENUS, and SPECIES that they belong to!

7. Did you know… …that approximately 1.9 Million species have been Classified so far? …that at least 1 Million of these are insects? …that it is believed that MANY others exist and just haven’t been discovered yet?

8. The process of arranging something according to shared qualities or characteristics. What does Classification mean?

9. How do we Classify?  Structural (anatomy and physiology)  Biochemical (enzymes, proteins, DNA)  Cytological (cell structure)  Embryological (growth and development)  Behavioral (patterns of actions)  Fossil (related to other organisms?)

10. Why should we Classify organisms?

11. Remember who this is? Lepus arcticus Arctic Hare Snowshoe Hare Polar Rabbit Poolhaas (Dutch) lièvre arctique (French) Scientific Name: Common Names: Is this a problem?

12. There is Confusion in Using Different Languages for Names

13. …but Latin Names are Understood by all Scientists

14. Defining Classification Classification: (Taxonomy) The scientific discipline where scientists “classify” organisms and group them in a logical manner. Based on what….? Anatomical Structure Cell Structure DNA Growth and Development Behavior

15. History of Taxonomy Carolus Linnaeus: “Father of Taxonomy” In 1735 … Developed the basis for our modern classification system.

19. Quick Classification Activity: Get out your Bell Ringer for Today… You already listed your 8 favorite organisms. Next… Quickly separate them into 2 logical groups based upon a characteristic or behavior. Next…Separate those two groups into 4 groups based upon a different characteristic or behavior. Finally…Separate those four groups into the 8 individual species based upon a different characteristic or behavior.

21. Scientific Naming Binomial Nomenclature: A two-word naming system Why? To eliminate the confusion that arises when people use common names

22. How? –Latin –Two Names: Genus and species –Always written in italics. –Genus is capitalized –Species is lower cased First Name Second Name Genus species Example: Lepus arcticus Other Examples: Ursus arctos (Grizzly Bear) Ursus maritimus (Polar Bear) Ailuropoda melanoleuca (Panda Bear) Scientific Naming

23. Which TWO are more closely related? Scientific Naming

24. http://www.backofthecerealbox.com/2012/07/nine-animals-that- got-screwed-when.html Here are some animals that got screwed when they were handing out Scientific Names! Bison bison Chinchilla chinchilla Iguana iguana Mephitis mephitis Rattus rattus Ghecko ghecko Lynx lynx Gorilla gorlla Mops mops

Grizzly bearBlack bearGiant panda Red fox Abert squirrel Coral snake Sea star KINGDOM Animalia PHYLUM Chordata CLASS Mammalia ORDER Carnivora FAMILY Ursidae GENUS Ursus SPECIES Ursus arctos Section 18-1 Go to Section: Classification of Ursus arctos (Grizzly Bear) Do Ursus arctos and Ursus maritimus belong to the same species?

27. SCIENTIFIC NAMING PRACTICE: WRITE YOUR NAME USING BIONOMIAL NOMENCLATURE Mcfarlandus scotticus My Scientific Name is…. Sounds Latin? Two words? Genus and species? Genus is capitalized? Entire scientific name is italicized?

28. What do you do if you think you have discovered a New Species?

29. Collect a specimen! Run a Dichotomous Key

30. Dichotomous Key (Biological Key)  Tool used by biologists to identify an unknown organism  Series of paired statements of anatomical description that leads to an identification.

31. Dichotomous Key Step 1 If fish shape is long and skinny then go to step 2 If fish shape is not long and skinny, then go to step 3 Step 2 If fish has pointed fins, it is a trumpet fish If fish has smooth fins, it is a spotted moray eel Step 3 If fish has both eyes on top of the head, then go to step 4 If fish has one eye on each side of the head, then go to step 5 Step 4 If fish has long whip-like tail, it is a spotted eagle ray If fish has short, blunt tail, it is a peacock flounder Step 5 If fish has spots, then go to step 6 If fish does not have spots, then go to step 7 Step 6 If fish has chin "whiskers," it is a spotted goat fish If fish does not have chin "whiskers," it is a band-tail puffer Step 7 If fish has stripes, then go to step 8 If fish does not have stripes, it is a glassy sweeper Step 8 If fish has a v-shaped tail, it is a squirrel fish If fish has a blunt tail, it is a glass-eye snapper 123 456 798 Always start here!
