5. What is Taxonomy?
The science or discipline of classifying organisms and assigning each organism a universally accepted name.

6. Why Classify?
To study the diversity of life, biologists use a classification system to name organisms and group them in a logical manner.
When taxonomists classify organisms, they organize them into groups that have biological significance.

7. Assigning Scientific Names
Aristotle
Greek philosopher who was the first to classify or group living things.
He classified organisms into two groups:
Plants and Animals
He subdivided those groups as well.
Plants were subdivided into: Herbs, Shrubs and Trees
Animals were subdivided based on their habitat and physical characteristics

8. Assigning Scientific Names
Carl Linnaeus
A Swedish botanist developed Binomial Nomenclature, a two- word naming system for naming all species on earth.
It is based on physical and structural similarities
Still used today

10. Common Names vs. Scientific Names
Common Names can be confusing, one organism can have many different names
The Cougar is also known as a: Puma, Mountain Lion or Catamount
Each organism only has ONE scientific name (species name)
No matter where you are in the world the Cougar is Puma concolor

11. Why does everything have a weird name in Biology?
Many things in science are named using Latin.
Why?
Latin is a dead language and won’t change meanings with slang or invention.

12. 4 Reasons for using Latin
dead language and will not change
not misleading like a common name
more descriptive
basis for many other languages; English, French, Spanish, Italian and Portuguese

13. Binomial Nomenclature
Each organism has a name consisting of two words
Examples:
Homo sapiens Tyto alba
Common Names:
HUMAN
Barn Owl

14. Binomial Nomenclature
Homo sapiens Tyto alba
The first part of the scientific name is the genus. This word is always written first and the first letter is capitalized. It appears in italics or is underlined.

15. It appears in italics or is underlined.
Binomial Nomenclature
Homo sapiens Tyto alba
The second part of the scientific name is the specific epithet or species name. This word is always written second and the first letter is lower-case.
It appears in italics or is underlined.

17. The 8 Levels of Classification
They are, from largest (most inclusive)
to smallest (most specific)
Domain (this is a relatively new level separates Archaea, Bacteria and Eukaryota)
Kingdom (separates plants from animals)
Phylum (separates into major groups within the Kingdom; plural: phyla)
Class (breaks Phyla down into smaller groups)
Order (even more specific)
Family (very similar characteristics)
Genus (reproductive grouping)
Species (most specific)

18. Most Inclusive
The more levels of classification that two organisms share, the more closely related they are.
Most Specific
