Think 1.What traits do all animals have in common? 2.“ “ “ vertebrates have in common? 3.“ “ “ mammals have in common? 4.“ “ “ carnivores have in common?

Classification I can analyze biological classification systems.

Because of evolution there is great diversity of life!

CLASSIFICATION Scientists need to organize over 2 million organisms! Taxonomy: the study of classification of organisms Classification: grouping organisms based on common ancestors and characteristics. What are some common characteristics you can think of?

History of Classification How classification has changed over time?

At first… Classified organisms as either plants (plantae) or animals (animalia) Is every living thing a plant or animal?

Carolus Linneas Hierarchical system = classifies in levels uses clearly defined shared characteristics to classify organisms into each group represented by different levels

Classifications Kingdom < most general Phylum Class (Mammalia, Aves, Reptilia, and Amphibia) Order Family Genus Species < most specific

Carolus Linneas Binomial nomenclature = naming organism types with two names Second smallest level Smallest level Species: Genus: Homo sapiens Genus species

Systems of Classification What organism do you think this is based on the binomial (species name)? Canis familiaris Felis domesticus

Modern Classification Uses evolution!

CLASSIFICATION Scientists use the following criteria to classify organisms: – Structural similarities: similar fossils – Biochemical analysis: DNA, proteins and amino acids – Embryology: similar embryos

THINK What is classification? What were the 2 kingdoms at first? What is the most GENERAL level? What is the most SPECIFIC level?

Kingdoms

Review: What is the difference between a prokaryotic and eukaryotic organism? What is the difference between a unicellular and multicellular organism? What is the difference between an autotrophic and heterotrophic organism? What is the difference between sexual and asexual reproduction?

Gallery Walk Students will be able to identify the kingdom of an organism from its description. – Using your newfound knowledge of the taxonomy (classification), you must now help place each organism into the correct kingdom. Procedure 1.Look at the pictures of the organism. Read the paragraph describing the organism, its habitat, and its method of obtaining food. 2.Use your chart describing the characteristics of the six kingdoms to identify the kingdom the organism belongs to. 3.Place the name of the kingdom in the appropriate blank. 4.When you have identified the kingdom of each organism at your station, move to the next station as directed by your instructor. 5.Continue until you identify the kingdom of all 20 organisms.
