1. WARM-UP: What do you call these animals?
Turn in review if you didn’t yesterday. Have out Taxonomy WS for me to check.
WARM-UP: What do you call these animals?
Common Names: Red bird Rabbit
Cardinal Bunny
Northern Cardinal Hare Jack Rabbit
Scientific Names: Cardinalis cardinalis Lupus californicus

2. What would you call this
What would you call this? Guy, man, person, human, human being, boy…common names go on and on and on, but he has an actual name!!! Just like you have a real name to identify you, so do organisms!

3. Taxonomy
The science of naming and classifying organisms

4. Classification System:
Domain:
Kingdom
Phylum
Class
Order
Family
Genus
Species
Goes from inclusive (broad/includes many animals) to specific (SPECIes = SPECIfic)
Now includes an additional level above Kingdom called “domain”
There are 3 domains:
Bacteria
Archea
Eukarya
What do you notice about this? Student responses: goes from wide to small; many animals in the top layer, only 1 in the bottom layer; there’s 7 different species in the top layer, and the one bear on the bottom layer. What does Eukarya remind you of? (eukaryotes) and what do eukaryotes have? (nucleus) Are animals (humans) eukaryotes? So what domain is this example representing? (eukarya) they need to add it. If Eukarya means they’re eukaryotes and have a nucleus, what do you think Bacteria and Archea are? (prokaryotes – no nucleus)

6. CFU: Why do we need a naming system?
: Carolus Linnaeus
Set up a classification system based on morphology (how they looked)
Developed a naming system called binomial nomenclature
(bi = two, nomial = name)
First word: Genus and is capitalized
Second word: species and is lower case
Both are in italics
Written as: Genus species
Ex. Homo sapiens
H. sapiens
Still used today. The universal language for scientists always written in Latin (scientific language) because it hardly ever changes and what was used in the very beginning.
CFU: Why do we need a naming system?

7. Taxonomic Keys (Dichotomous key)
A key used to help identify and name an organism based on morphology
You work through paired statements, selecting the correct one until the name is given

8. Phylogeny: the evolutionary history of an organism
Scientists construct a phylogenetic tree or a cladogram to show the history
Can tell you three things:
That the organisms all came from a common ancestor
How related the organisms are
When the organism branched off and was formed
CFU: What is the common ancestor on the tree?

9. Cladogram used to show the evolutionary history of organisms
Can also show derived characters – when a particular characteristic first began
Circle one of the derived characters and label it a derived character

10. Writing Prompt
Must be at least 1.5 pages long. In complete sentences answer the following: Why is lab safety important? Give examples of lab safety. Ex. you can give a lab safety rule and talk about why it’s needed, what could happen if it wasn’t followed etc.

11. Answer the dichotomous key/cladogram Questions on your own
