1. Classification Taxonomy
A way of organizing living organisms
Showing ancestral relationships

2. History Linnaeus – Swiss – lived in the late 1700’s
Devised our scheme of taxonomy – naming living organisms
Binomial naming scheme
2 Latin-word name
Genus (small group of similar organisms)
Species (Specific name within that group)

3. Why do we classify?
Different regions call the same animal by different names
Panther, mountain lion, cougar - all the same animal called by different names regionally
Puma concolor
What is the animal’s genus?
Species?
Organizational scheme by similar qualities into groups of related organisms

4. Mammals What qualities do all mammals share? Homologous structures……
Remember from before – whale, bat, cat, human forearm – we are all MAMMALS
These structures help to show common ancestry and relatedness
Warm-blooded, nurse their young, bear live young, have fur

5. Relationships All Mammals
Lion Leopard Rabbit
Which are more closely related?
How do we know

6. How classification schema show these relationships:
Lion Animalia Chordata Mammalia Carnivora Felidae Panthera P. leo
Leopard Rabbit
Animalia Animalia
Chordata Chordata
Mammalia Mammalia
Carnivora Lagamorpha
Felidae Leporidae
Panthera Oryctolagus
P. pardus O. cuniculus

7. How to remember the levels
Kingdom - (animal, Plant, Fungus, Archaea)
Phyum ( chordate/non-chordate)
does it have a backbone?
Class (mammal, aves, reptilia)
Order (carnivore, rodentia, ungulate, Primate)
Family - (felidae [cats], canidae [dogs],
hominidae [humans]
Genus – (leo, panthera, felis)
Species – Panthera pardus (leoplard)
Kinky

Sex

9. How many different classes are represented in this chart?
How many Orders are represented in this chart?
Is a catbird more like a chicken or a lion?
How do you know from the classification chart?
What kind of animal is a catbird – how do you know from the chart?

10.  5- Kingdoms
Plantae – Can produce their own food from sun and carbon dioxide. Cells have cell walls for support
Animal – take in food and nutrients from other sources. No cell walls – animals have bones for support
Fungus – obtain food through decomposing other organic material
Bacteria – Single cell or unicellular. - No nucleus
Protists – single cell organisms – some are animal-like, some plant-like, some fungus-like

11. What does this cladogram show about the relationship of the 5 animals?

12. Which Kingdom?
Make their own food
Unicellular
Decomposers

13. 3 Domains Eukaryotes – organisms with cells with a nucleus to hold DNA
We are eukaryotes as are plants
Prokaryotes – have no nucleus – DNA is free floating
Bacteria are prokaryotes
Archeae – Similar to prokaryotes – recently put it their own domain
