In this unit, the summary is shown in blue, and the underlined words are vocabulary; the animation and video hyperlinks are shown in orange.

 Scientists classify the diverse number of organisms on the planet in order to learn and study from them into hierarchical groups.  In this unit you will learn how scientists classify living things; the science of taxonomy. ◦ the arrangement of organisms into orderly groups based on similarities

 Von Linne [AKA Carolus Linnaeus] was the Swedish biologist who in the mid- 1700’s developed the biological system of classification. ◦ 7 taxonomic levels [or taxa] ◦ kingdom to species  Video Video

1.A common name eliminates confusion caused by regional name differences. ◦ EX crayfish, crawdad, mudbug are all common names for…. ◦ Cambarus bartoni fangq/food/HuifangCookings/edited/crawfish.jpg

◦ Mountain lion, panther, cougar and puma are all common names for... ◦ Puma concolor

◦ Roly poly, pillbug, and wood louse are all common names for... ◦ Armadillidium vulgare

2.organizes large amounts of information 3.Classification also reveals evolutionary relationships between organisms

 When instructed, pick up a colored piece of paper at the front to create your mnemonic foldable.  Each pod will need some scissors.

 Domain  Kingdom  Phylum  Class  Order  Family  Genus  Species

 Domain is the most recently added 8 th taxonomic level, which is even more inclusive than a kingdom.  There are 3 domains shown above – 2 are prokaryotic, 1is eukaryotic. ◦ Video Video

 Six kingdoms of life:  4 Eukaryotic Kingdoms ◦ Animals ◦ Plants ◦ Fungi ◦ Protists  2 Prokaryotic Kingdoms ◦ Archaebacteria ◦ Eubacteria y_abocOeLKk/TpuITAAu8VI/AAAAAAAAHuw/SJdeqGFpZ8E/s1600/six+kingdoms+tree+of+li fe+.gif

 A species is a group of organisms that are very closely related and can breed fertile offspring.  Video Video

 In Latin, nomenclatura = ◦ nomen "name"+ calare "to call"  Scientists give each organism a name in classification which consists of two parts: ◦ genus + species [specific epithet]. ◦ Typically use Latin because it is universal [worldwide] and not widely spoken, therefore, the meaning is not likely to change.

EX Tyrannosaurus rex translates to “tyrant lizard”+“king.”

 Always in italics  Genus name is written 1 st, capitalized  Species name is written 2 nd, NOT capitalized  EX scientific names ◦ Homo sapiens (modern man) ◦ Felis catus (common housecat) ◦ Video Video
