Presentation transcript:

Linnaeus’ Taxonomy Taxonomy is any method of classification.

Reasons for Using a Classification System: n Clarification of species n Allows for world-wide research

How Linnaeus’ System Works:

Kingdom: n The largest and most general taxon –Type of cells –Number of cells –Method of getting food

Kingdom: Animalia n Eukaryote: well defined nucleus n Multicellular: more than one cell n Heterotroph: food from an outside source

Kingdoms are Divided into Phyla:

Phylum Chordata: n Backbone n Paired appendages

Phyla are Divided into Classes:

Class: Mammalia n Diaphragm n Hair/fur n mammary glands

Classes are Divided into Orders:

The Primate Order: n Complex Brain n Opposable thumb n Stereovision n Separate radius and ulna n Fingernails

Types of Primates: n Apes n Humans n Prosimians n Monkeys –New World –Old World

Prosimians are: Lemurs & Tarsiers Ringtail Lemur Philippine Tarsier: Tarsius syrichta

Orders are Divided into Families:

Characteristics of Hominidae: n Walk upright n Small face and teeth relative to other primates n Large brain capacity

Families are Divided into Genera:

Characteristics of the Genus Homo: n Largest cranial capacity of any primate. n Cranial capacity increases with time.

Genera are divided into Species Homo erectus neanderthalis vs. sapiens sapiens

Modern Humans Homo sapiens sapiens Leonardo Da Vinci
