Classification of Life

Classifying Organisms Classification: is the
process of grouping things based on their similarities.
Non living things can be classified based up external features like hard vs. soft, round vs. triangular, or big vs. small.
Example: You could classify sports equipment based on it’s external features

It’s Your Turn-Classify This Now it’s your turn try
classifying the following items. Remember you can group them together based on a variety of physical characteristics.
Here’s your items: SCOTCH TAPE, PENCILS, RUBBER BANDS, STAMPS, MARKERS, ERASERS, RULERS, ENVELOPES, PAPER CLIPS, and PAPER.
Be Prepared to Share your Answer!!!

How did you classify things?
How did you classify things?
What was your criteria or external features you based your classification on?
Could you have picked a different characteristic and classified things differently?

Taxonomy Taxonomy is the scientific
study of how Living Things are classified.
There are 1.7 million known species of plants, animals, bacteria, etc.
There is constantly new organisms being discovered and it’s important for biologists to have all living things organized.

Classification is Important Classification is
important because… 1. It helps identify
unknown organisms 2. It helps us to
realize what types of organisms are surviving and why they are surviving.
3. It helps us organize information we learn about new organisms.

Why is Classification Important? Imagine you walk into a library and
ask for a book on “Whales” and the librarian says I know I have a book on whales its somewhere in here but I’m not sure where.
If you wanted to find your book on “Whales” you would have to look through hundreds and thousands of books to find the book you want. This would be a giant waste of time.
Classification systems are important because they organize our knowledge for us.
When things get sorted into groups it makes them easier to understand and it makes it easier to see the relationships between them.

Carolus Linnaeus Classification System
Carl Linnaeus was a Swedish scientist in the 1750’s. (notice the cool wig he must have been the talk of the town)
He developed a classification system that we still use parts of today

Carl Linnaeus Classification System
Linnaeus developed a naming system called binomial nomenclature where each organism is given a two part name.
The first part of an organisms name is its genus.
A genus is a classification grouping that contains similar or closely related organisms.
![Page 10: Classification: is the process of grouping things based on their similarities. Non living things can be classified based up external features like.](https://reader031.fdocuments.in/reader031/viewer/2022031809/56649d0a5503460f949dc35a/html5/thumbnails/10.jpg)
Carl Linnaeus Classification System The second part of the
naming system is the species.
A species is a group of similar organisms that can mate and produce fertile offspring in nature
What is the genus and species name for human beings?
Homo sapien Notice the Genus is
capitalized and the species is not.
When you go to the zoo they will often times have the genus and species names listed.

4 Organisms I have 4 Organisms
and I know their genus and species names. Of the following organisms which are most closely related?
1. Canis lupus 2. Megaptera
novaeangliae 3. Ailurus fulgens 4. Canis rufus

4 Organisms 1. Canis lupus
(Grey Wolf) 2. Megaptera
novaeangliae (Humpback Whale)
3. Ailurus fulgens (Red Panda)
4. Canis rufus (Red Wolf)

Classification Today Modern
classification has changed because often times in addition to classifying organisms on external characteristics we use genetic similarities. (If they have similar DNA)

Classification Today Classification today uses 7
levels to classify organisms. For example how many
people in this room live in Utah?
How many people have ever left the state of Utah?
How many people have ever lived somewhere besides Utah?
How many people have lived in a different country?
For each question your larger classification group gets smaller and breaks down into sub-groups.

to research an organism it has their classification groups on there

Classification Key Classification Key is a series of
paired statements that describe the physical characteristics of an organism. (This is also known as a Dichotomous Key or Taxonomic Key)
Taxonomic Keys helps you identify the organisms you are looking at.
Have you ever went hiking and wondered what the name of the trees, flowers, or insects around you are?
Money Taxonomy Key Have you ever played the 20
Questions Game? It uses the same principle in sorting similar characteristics until it knows what you are thinking

The 6 Kingdoms: To Be Continued…….
The Six Kingdoms that we divide life up into are: Archaebacteria, Eubacteria, Protists, Fungi, Plants, and Animals.
Some people now divide the kingdoms into 5 where they have combined Archaebacteria and Eubacteria into a Kingdom called Monera
