  1. CLASSIFICATION What does the word classify mean? • 1. Classify -

  2. Why do Scientists Classify? __________________________________ _______________! Need to keep organized! (Easier to study!) ...just like we need to keep grocery stores organized so that it is easier to shop!

  3. Why do Scientists Classify? • Taxonomy =________________________________________________________. Useful because: ____________________________________________________________________.

  4. WHAT’S IN A NAME? • Scientists have a system for naming all the living organisms on earth. • The system was________________ • __________________________. • Developed__________________. • Linnaeus designed Bi = Nomial =

  5. Binomial nomenclature: _________ _______________________________________________________________________________________________________________________________________.

  6. Linneaus’_________________________ Each species of a living thing is given a________ _______. EX: Just like your first and last name First Name (______) • Tells______________________________________________. __________(_______) • Tells______________________________ • ________________________________.

  7. Linneaus’ System of Scientific Names • Example:Scientific Name for a dog _________________ • Scientific Name for a Timber Wolf _________________ • Scientific Name for a Coyote _________________ • Notice that the word __________ is used in all of these names. _______________________________. • ___________________________________________. • _____________________________________________.

  8. 3. or both words are underlined Canisfamiliaris DO NOT underline space between words!!! Linneaus' System of Scientific Names Binomial Nomenclature - Rules Example:Canis familiaris 1. 2.

  9. Now that you know the three rules of writing scientific names, let's try one: Common Name: Genus: (Derived from the Latin word Hominid, meaning “man”) Species: (The Latin word for “wise”) Scientific name: _________________.

  10. How Are Living Things Classified? • There are ___________in _____________________ • ____________________. • As one goes from the ______________________________________________________________. • As one goes downward _________________________________________.

  11. How Are Living Things Classified Cont’d? • ___________: • ___________: A ___________of a kingdom. • ___________: Each _________ is divided into • ___________: • ___________: Each order is divided into families • ___________: Each family is divided into genera • ___________:

  12. How Are Living Things Classified Cont’d? Classwork: Write an original catch phrase for the categories of classification so that each word in the phrase begins with the letter of the category in their correct order from largest to smallest Example:Kids play cards on fat green stools Species Phyllum Order Family Kingdom Class Genus

  13. HOW CLASSIFICATION WORKS __________________: The ring-tailed lemur

  14. KINGDOM There are 6 Kingdoms: ________________ (Animal Kingdom) ______________ (Plant Kingdom) _____________ (Fungus Kingdom) ________________(Ancient Bacteria) _______________ (Advanced Bacteria) _______________ (Protists) There are a total of TWO MILLION SPECIES within all the Kingdoms! We must narrow it down!

  15. PHYLA EXAMPLES There approximately________________________... Approximately_________________. (Much better than 2 million, but still a lot!) Porifera- ________________________. ___________– stemmed from the greek word “cnido”, these are animals that _______________. Chordata- _______________________. ___________- the body of the animal is segmented and has no jointed limbs _______________-these are marine animals that have ________________.

  16. CLASS EXAMPLES There are ____________________________. _____________The Latin word Reptili means “creepy”, or___________________. Class Amphibia- Amphi= double bia=life, _____________ ________________________________________. _______________- The Latin word mammali means to suckle. ______________________________________ ____________________________. Class Aves- “Avi” means to fly. These are flying animals.

  17. CLASSIFICATION • So far the Ring-Tailed Lemur belongs to: • Kingdom- Animalia • Phylum- Chordata • Class- Mammalia Which taxonomy level comes after class? _________________________

  18. ORDER EXAMPLES In class Mammalia, there are 13 total orders that make up about 5,000 species. Getting closer! Order Metatheria- _________________ (development completed in a pouch). Order _______________- This is where the carnivorous mammals belong such as raccoons. Order Chiroptera- Chiro=hand, ptera= wing. Mammals that use_____________________. Order Rodentia: mammals with __________ __________________________. Order Primates- mammals that have _________________________________________.

  19. FAMILIES WITHIN THE PRIMATE ORDER The primate order consists of 10 families and approximately 350 species. Hominidae (___ species)- Latin word meaning _______________. Pongidae (28 species)- ______________. Cebidae (46 species)______________. Cercopithicidae (48 species)- Old world monkeys Lemuridae (____ species) The large lemurs, the Latin word Lemur means “___________.” Chosen for their ghostly faces and (for some) nocturnal habits.

  20. GENERA WITHIN THE LEMUR FAMILY Eulemar- the brown lemurs Hapalemur- small lemurs that eat bamboo Lemur- ____________________(________________).

  21. Kingdom: Animalia Phylum: Chordata Class: Mammalia Order: Primates Family: Lemuridae Genus: Lemur Species: Catta Scientific Name: Lemurcatta From this classification, we know that the ring-tailed lemur is an ________________________________________________________________________________________________________________________.
