Transcript of Animal Classification

The study of organisms

similarities and differences

Classification
Why are there so many different organisms on earth?
Earth's Diversity
Why do some of these different organisms have similar characteristics?
We can organize all LIFE by their
structure
and
function
Organization of Life
Group organisms together based on anatomical similarities
Scientists group all living things into the following six kingdoms
Classification
Domain: PROKARYOTES
Domain: EUKARYOTES
Classification:
The systematic grouping of organisms into categories on the basis of evolutionary relationships or physical appearance.
Make
observations
:
Ask
questions
Based on
observations
:
The questions have to have
"YES"
OR "
NO"
answers.
Radial Symmetry
Bilateral Symmetry
Asymmetrical
Animals
Archaebacteria
Bacteria
Domain
Kingdom
Phylum
Class
Order
Family
Genus
Species
We can organize these six kingdoms even further!
How Do We Classify Exactly?
Why Organize?

Allows us to keep track of the
3 to 10 million different living things
on Earth.
Protists
Fungi
Plants
Animals
Earth's Unity
1a. Does eat Meat.........go to 2
1b. Does not eat meat

2a. Is larger size........go to 3
2b. Is smaller size

3a. Is a carnivore
3b. Is an omnivore
Identify the Animal
Does it have a longer neck?
Does it have a shorter neck?

Does it not have stripes?
Does it have stripes?

Is the body covered in stripes?
Is the bosy not covered in stripes?
zebra
okapi
Archaebacteria
Protists
Fungi
Plants
Bacteria
Archaebacteria are found in extreme environments:

- boiling water
- thermal vents
- no
oxygen
- highly acidic environments
Complex and single celled.

There are many kinds and they are found everywhere - most are beneficial.
- many
sizes

and
shapes
Slime molds and algae are protists.

Sometimes they are called the
odds and ends
kingdom because its members
are so different from one another.

Protists include all microscopic organisms that are not bacteria, not animals, not plants and not fungi.
Examples of fungi:

- mushrooms
- mold
- mildew

Most fungi are multicellular and consists of many complex cells.
Plants are multi-cellular organisms that produce their own food.

Examples of plants:
- flowering plants
- conifers
- mosses
- ferns



With over 250,000 species, the plant kingdom is the second largest kingdom.
The animal kingdom is the largest kingdom with over 1 million known species

Animals can mate if they
are the same species!
Classification continued...
We name animals using
Binomial Nomenclature:
- “Binomial” =
two-name
- “Nomenclature” =
naming system









*Genus is always capitalized

-
Species is always lower-case
* Both are always italicized
There are 7 levels of classification that describe a species
Felis domesticus
Felis concolor
Felis rufus

Genus

species
Genus and species are the most specific levels of organization
How Do We Name Organisms We Classify?

Genus

species

Genus

species
Can be classified together because they all produce milk (mammal)
Can be classified together because they all have same characteristics.
(claws, fur, strong upper limbs)
More About The Kingdoms...
Example:
Does it has symmetry? YES.........
Next Q
Is it a circle?........YES...
It's a Sea Urchin!
Organize questions onto a chart called a
Dichotomous Key
.

Questions must have a
"yes" or "no"
answer.
The more levels of organization that two organisms share, the more closely related the two organisms are!

All organisms:
- have DNA
- can grow and develop
- reproduce
- respond to stimuli
- keep homeostasis (a balance)
- obtain and use energy
