3. TAXONOMY

4. What is Taxonomy
Science of grouping and naming organisms based on similarities.

5. What are the modern taxonomic levels we will use in Zoology?
Dear
Domain
Mneumonic Device
King
Kingdom
Phillip
Phylum
Came
Class
Over
Order
For
Family
Great
Genus
Spaghetti
Species

6. According to this diagram, what is the biggest, most general category?
Kingdom
What is the smallest, most specific category?
Species

8. Which two organisms are most closely related?#1 #2 #3 #4

acuta
Humans Lion Tiger Pintail Duck
Which two organisms are most closely related?
2 & 3
Which organism is the least related to the other three? #4

9. What is this animal called?
Cougar, Mtn lion, Puma?
Depends on where you live…
The names used above are common names.
Scientists use scientific names when referring to organisms.
Using scientific names reduces confusion of using regional names.

10. What’s in a name… a scientific name…
Always written in Latin (old, dead lang.)
Italicized when typed, underline when written
First word is always capitalized genus name (ex: Homo)
Second word is always lowercase species name (ex: sapien)
A dog, Canis domesticus

11. Scientific names cont’d…
Species name can represent:
Color- ex: Acer rubrum is a red maple
Who discovered it- ex: Cyriopalus wallacei is a beetle discovered by Alfred Russell Wallace
Place where discovered- ex: Aplysia californica is a California Sea Hare

12. The NEW category… the DOMAIN…
Domains are categories that are larger than kingdoms.
Three domains
Bacteria
Includes Kingdom Eubacteria
Archaea
Includes Kingdom Archaebacteria
Eukarya
Includes protists, fungi, plants, animals

13. some autotrophic, most chemotrophic prokaryote “extremophiles”

some autotrophic, most chemotrophic
prokaryote
“extremophiles”
Bacteria
Eubacteria
autotrophic and heterotrophic
bacteria, E. coli
Eukarya
Protista
most unicellular
heterotrophic or autotrophic
eukaryote
ameba,
paramecium, algae
Fungae
most multicellular
heterotrophic
mushrooms, yeast
Plantae
multicellular
autotrophic
trees, grass
Animalia
humans, insects, worms

14. How are cladograms used in Zoology?
Show evolutionary relationships
Show when certain traits evolved
Like a family tree
Everything from the perch up has jaws. Organisms below jaws never developed that trait
Everything from the lizard up has claws/nails. Organisms below that trait do not have that trait.

15. Which two animals are more closely related?
Which two animals are least closely related?
Chimp & Bonobo
Gibbon & Human

16. What do scientists observe to determine placement of an unknown organism?
Biochemical similarities (DNA)
Morphology (structures)
Physiology (similar working parts)
Developmental similarities (embryos)

17. When are dichotomous keys used?
1. Type of tool used to identify unknown organisms.
2. Use a series of steps to identify an organism starting with its most general traits & ending with its most specific traits.
How to read one:
Read 1st two statements. Which ever is correct about your organism, follow the instructions. Keep doing this until you reach a scientific name.
