Intro to Classification
Transcript of Intro to Classification
What does it mean?
The grouping of objects and organisms based on similar characteristics
Biotic or abiotic factors can be classified
What criteria did you use to group the cut objects?
Why do we need to classify organisms?
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....
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
"The Diversity of Life"
Highest number of different species
Lowest number of different species
Who is responsible?
- the scientific study of how things are classified
are responsible for grouping organisms
as taxonomists learn more about organisms, classifications
choices in each step
allows the user to group items with
as the groups become more specific, there are fewer items/organisms contained within
allows the user to identify
constructed so that the user is given a series of
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
Getting to know
first system of classification
(way way back in the
(IMPORTANT in Science!)
How did Aristotle do it?
grouped animals based upon their
way they moved
Why did it work?
Why did it fail?
Using Aristotle's system of classification, classify the following organisms:
Who was Carolus Linnaeus?
liked Aristotle's work
made his own system
used careful observation
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
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!
Phylum (pl. = phyla)
Genus (pl. = genera)
**although we will not study it, there is a level of classification above Kingdom called Domain
King Phillip Came Over For Green Spaghetti
Within your group, create your own mnemonic device
# of Kingdoms
Greatest # of organisms
only 1 organism can have a particular species name
Genus (pl.= genera)
Phylum (pl.= phyla)
