Rules of Classification Date

Objective: Who was Linneaus and what did he do?Be able to write a Scientific Name

correctly.Memorize and understand how the Levels

of Classification work.

Vocabulary Matching1. Classification ?

2. Biologist ?

3. Taxonomy?

A. The process of grouping things based on their similarities including their evolution and relatedness (putting into groups)

B. The scientific study of how living things are classified (process of identifying, describing, naming and assigning to a group)

C. A life-study-person who classifies organisms so it’s easier to study them

Recent New Species

Why Classify? Currently there are 2-1/2 million identified organisms Approximately 1 million still waiting to be identified in rainforests Unknown amount in waters not yet explored

1750’s Carolus LinneausProblems: Names like

“Oak with deeply divided leaves that have no hairs on their underside and no teeth around their edges”

was much, much, much too long and confusing.

By accident scientists saw Linnaeus’ notes in the margin with a shortened two part descriptive name of the organisms.

Deeply divided-

no teeth

“Binomial Nomenclature”- a two part-scientific descriptive name in Latin.

Genus- first part-describes closely related organisms.

species- second part-similar organism that can mate and produce fertile offspring in nature and may describe its habitat or color.

Example:

-needs to be italicized when typed Homo sapien ( man -wise, rational)

-underlined when handwritten Homo sapien

Examples of Binomial Nomenclature:

Organisms Genus Species

Pumas Felis concolor(the same color)

Ocelets Felis paradalis (spotted & like a panther)

House cat Felis domesticus(of the house)

Ursus horribilis

????????

“bear-feared”

Binomial Nomenclature Avoids Confusion

For example:

Common Names Scientific Name

Long straw pine Pinus taedaIndian pine

Many common names:

puncturevine, caltrop, cathead,

yellow vine, goathead,

burra gokharu and bindii

One Scientific Name: Tribulus terrestris

Starfish ?

Sea horse ?

Sea cucumber ?

Jelly fish ?

Reindeer moss ?

Know what items are being classified Make many observations about the things to be classified Classify the things based on the observations Try to group the most similar things together. When grouping living things, place the most similar organisms in the same species. The largest, or most general group of living things is the kingdom.
