CH.15 Classification Systems Taxonomy Taxonomy : - the science of classification

I.Why Classify? A.Reasons for Classifying 1.Convenience 2.Communication 3.Studying and understanding

B.Characteristics of Scientific Classification 1.Unique, universal name for organisms 2.Puts organisms into meaningful groups

II.Biological Classification A.Aristotle: - devised first classification system -2 kingdoms: Plants and Animals -2 problems: 1. superficial classification 2. used common names

B.Disadvantages of Common Names 1.Confusing Puma concolor -ex. mountain lion, cougar, puma, catamount, panther

2.Misleading - ex. starfish, jellyfish, cuttlefish, silverfish, crawfish

2.Misleading - ex. starfish, jellyfish, cuttlefish, silverfish, crawfish - none are fish

3.Language Problems -local names -names used by different languages

C.Carolus Linnaeus -developed modern classification system -Swedish botanist (1700’s) -2 important innovations:

Animalia Chordata Mammalia Carnivora Canidae Canis lupus Kingdom Phylum Class Order Family Genus Species 1.Hierarchy of Classification Groupings

King Phillip comes often for ginger snaps Animalia Chordata Mammalia Carnivora Canidae Canis lupus Kingdom Phylum Class Order Family Genus Species 1.Hierarchy of Classification Groupings

Kingdom Phylum Class Order Family Genus Species

- Order Carnivora

2.Binomial Nomenclature - two-word naming system: genus & species - gives a unique, universal name for every species Carolus Linnaeus

Honey Bee Apis pubescens, thorace subgriseo, abdomine fusco, pedibus posticis glabris, utrinque margine ciliatus Apis mellifera

a.Genus: -1st word, small group -usually a Latin noun, capitalized b.Species: -2nd word, particular type -Latin adjective, lower case

c.Examples: - Homo sapiens humans - Tyrannosaurus rex - Acer macrophyllumbigleaf maple - Acer rubrumred maple - Acer saccharumsugar maple - Sequoia gigantumgiant sequoia - Tsuga heterophyllumwestern hemlock - Pseudotsuga menziesiiDouglas-fir

III.Taxonomy Today -Classification systems change constantly - Taxonomists do not agree on how to classify organisms (lumpers vs. splitters) - Species is the only "real" (natural) taxonomic grouping

A.Taxonomy and Evolution - taxonomy reflects evolutionary relationships

Phylogeny of Bears MYA

-The greater the similarities in certain organic compounds, the more closely related organisms are. -DNA, RNA, & certain common proteins can be compared between organisms. B.Biochemical Taxonomy
