Unit 8: Classification How do we organize life? You woke up this morning and your little brother had eaten all the cereal. You need to run to the grocery store to pick up Frosted Flakes. Explain

how you would tell someone where to get the Frosted Flakes from. STEP BY STEP! Why do we group things? -

how they are similar find where new organisms belong differences between organisms tell which ones are related Taxonomy -The science of classification is called

taxonomy -Taxonomist are like living organism detectives searching for new organisms and trying to find where they belong How has Taxonomy Changed? -The way we group organisms has changed

over time because we know so much more about animals/plants etc than we did before -Technology allows us to see relationships Old Method: Aristotle Old method invented in the 300s BC was by philosopher named Aristotle, he called his

method the Ladder of nature grouping organisms from most complex to least complex - He didnt have a microscope so he was leaving out a huge group of organisms 2 Original Kingdoms: 1. Animals

a. Blood i. Live Babies ii. Laid Eggs b. No Blood 2. Plants Old Method: Aristotle

- At this point there was no method for naming organisms - Each scientist used his own method based on what he thought was most important Ex. Animal furry bark; Animal furry meow Linneaus

Carl Von Linne: created a universal system for naming organisms Everyone would use the same names Linneaus

Created a category with the most diversity and then made subgroups of each category

Howd we fix the naming problem? Linneaus decided we would give each organism a two part name (sort of like us) Called Binomial Nomenclature Binomial Nomenclature Two Part Name

Genus Species Latin Name How to remember the taxa? At your tables come up with a sentence to help you remember the DKPCOFGS Ex. Did King Phillip come over for good soup?
