Classification copyright cmassengale

2 copyright cmassengale
Species of Organisms There are 13 billion known species of organisms This is only 5% of all organisms that ever lived!!!!! New organisms are still being found and identified copyright cmassengale

3 What is Classification?
Classification is the arrangement of organisms into orderly groups based on their similarities Uses same language (Latin or some Greek) for all names Classification is also known as taxonomy Taxonomists are scientists that identify & name organisms copyright cmassengale

4 copyright cmassengale
Early Taxonomists 2000 years ago, Aristotle was the first taxonomist Aristotle divided organisms into plants & animals He subdivided them by their habitat ---land, sea, or air dwellers copyright cmassengale

5 copyright cmassengale
Carolus Linnaeus 1707 – 1778 18th century taxonomist Classified organisms by their structure Developed naming system still used today Called the “Father of Taxonomy” Developed the modern system of naming known as binomial nomenclature Two-word name (Genus & species) copyright cmassengale

6 copyright cmassengale
Standardized Naming Binomial nomenclature used Genus species Latin or Greek Italicized in print Capitalize genus, but NOT species Underline when writing Turdus migratorius American Robin copyright cmassengale

7 Binomial Nomenclature
Which TWO are more closely related? copyright cmassengale

8 Classification Groups
Taxon ( taxa-plural) is a category into which related organisms are placed There is a hierarchy of groups (taxa) from broadest to most specific copyright cmassengale

9 Hierarchy-Taxonomic Groups
Domain Kingdom Phylum Class Order Family Genus Species BROADEST TAXON Genus and species are the two names used to identify specific organisms in the binomial system of classification. Division is used for plants. Most Specific copyright cmassengale

Cladogram Diagram showing how organisms are related based on shared, derived characteristics such as feathers, hair, or scales Shared history Clade: branch w/ a group of species that include a single common ancestor Unique history Shared or derived character time Node-speciation occurred- share a more recent common ancestor copyright cmassengale

14 copyright cmassengale
Is the chimp more closely related to a human or a Rhesus monkey? What features do Rhesus monkey, chimps, and humans share? Do the Rhesus monkey and chimp share a more recent common ancestor than the Rhesus monkey and Spider monkey? Primate Cladogram copyright cmassengale
