1-3 Classifying Organisms Pages 28-37

Classification and Taxonomy Process of grouping things based on similarities Biologists put them into groups so they are easier to identify and study Taxonomy- Study of how organisms are classified

Early Classification Systems Aristotle (384 BC – 322 BC)- 1st to classify Divided animals into 3 categories: Fly Swim Walk/run/crawl

Early Classification Systems Carolus Linnaeus (1707-1778)- Father of modern taxonomy and ecology Looked at body structures, body systems, and how they got their food Devised a naming system for organisms (still used today) Binomial Nomenclature (next slide)

Binomial Nomenclature Each organism is given a 2-part name (Genus, species) Genus: (always CAPITALIZED) 1st part of name groups with similar, closely related organisms Example: (pumas, ocelots, house cats) Genus= Felis species: (ALWAYS lowercase) 2nd part of name with similar organisms that can mate and produce fertile offspring. Very Specific (only pumas) Similar to our 1st and last name (always Latin)

7 Levels of Classification Kingdom Phylum Class Order Family Genus Species King, Phil, Comes, Over, For, Good, Spaghetti

7 Levels of Classification Not based on where they live Based on Shared Characteristics King, Phil, Comes, Over, For, Good, Spaghetti Goes from Broadest (biggest) more specific Classifying an owl Figure 12 page 33 **Show classifications on OH

Evolution and Classification Charles Darwin- wrote theory about how species change over time Has had a major impact on how species are classified Evolution- The process by which organisms change gradually over time.

Classification Today Species with similar evolutionary histories are classified more closely together This is done by: Studying Fossils Comparing Body Structures of living organisms (Fig. 14 pg. 35) Comparing Early development Examining chemical makeup (Figure 15 pg. 36) skunks and weasels

Using the Classification System May be used for camping. (spiders, snakes, scorpions) Field Guide- Books with illustrations (pictures) that highlight differences. Taxonomic Key- Series of paired statement that describe the physical characteristics of different organisms (Dichotomous Key)
