Transcript of Intro to Classification

Why are you so special?
Classification
What does it mean?

The grouping of objects and organisms based on similar characteristics


Biotic or abiotic factors can be classified
Classification
What criteria did you use to group the cut objects?
Why do we need to classify organisms?
What is
Biodiversity?

Write down 5 characteristics you observe of the above organism
By the end of this next week, you will understand how to classify objects and organisms and create your own dichotomous key....


Say WHAT?!!!!

Within your group, organize the cut out the shapes in the bag into groups in any way you want.

You have 2 minutes
an effort to organize things so they are easier to understand

developed because of the Earth’s large
biodiversity

"The Diversity of Life"
High Diversity
Low Diversity
Highest number of different species

Tropical Rainforest
Lowest number of different species

Tundra

Who is responsible?
taxonomy
- the scientific study of how things are classified

Taxonomists
are responsible for grouping organisms

as taxonomists learn more about organisms, classifications
can change
Tools of
Taxonomists
Di
chotomous Key
Taxonomic Key
"divided into
two
parts"
always give
two
choices in each step
allows the user to group items with
similarities
as the groups become more specific, there are fewer items/organisms contained within
allows the user to identify
unknown
organisms
constructed so that the user is given a series of
choices
about the characteristics of the unknown organisms
by making the correct choice at each step of the key, the user is ultimately led to the identity of a specimen

Aristotle!!

Greek
Philosopher
first system of classification
(way way back in the
300BCs!!!)
Made
careful observations
(IMPORTANT in Science!)
Plants
Animals
...but HOW?!
How did Aristotle do it?
grouped animals based upon their


habitat
and the
way they moved
walk/run/crawl
swim
fly

Why did it work?
Why did it fail?
Using Aristotle's system of classification, classify the following organisms:
CONTRIBUTORS!
Who was Carolus Linnaeus?
Swedish scientist
1700's
liked Aristotle's work
made his own system
used careful observation
Linneaus' System
Bi
nomial
Nomenclature
Scientific name
"Binomial Nomenclature"
**names use
Latin
roots**
Composed of organisms' genus and species names
What is a species?
a group of organisms that can mate and produce fertile offspring

Binomial Nomenclature Requirements
written Genus species
Italicize the name so it stands out from other text

genus name is ALWAYS capitalized
genus name ALWAYS comes first

species name is ALWAYS lower case
species name ALWAYS come last

**similar to last name first, first name last
i.e. Smith Jane
Classification Today
3 Main Characteristics:
uses binomial nomenclature to create an organisms’ scientific name
organisms with similar evolutionary histories are grouped more closely together
7 levels of classification
7 Levels of Organization!
Kingdom

Phylum (pl. = phyla)

Class

Order

Family

Genus (pl. = genera)

Species
**although we will not study it, there is a level of classification above Kingdom called Domain
