Rules of Classification
Every living organism on Earth is classified and name according to a set of
rules. These rules are used by scientists all over the world.
Scientists use a two name system
Organisms are grouped by their scientific name. This comes from a name
system called Binomial Naming System created by Carl Linnaeus. Okay,
Binomial Naming is just saying that it is a name with two words.
( bi = means two)
Lets break this down,
First part of the name describes the genus and the second part describes the
species. For example Homo sapiens (Humans)

Taxonomy
The taxonomy is a way of classifying organisms is based on similarities between
different organisms.
Define Analogous Structure
Define Homologous Structure
Taxonomy Explanation
• This system of biological classification groups animals and plants by
characteristics and relationships.
• Scientists looked at the characteristics or traits that each organism
have in common, which allows them to connect common ancestry.
• This system allows scientists all over the world to speak in the
language of science.
Taxonomy Break Down
King Phillip Came Over From Great Spain
This system describes an organism in a series steps or rules of thinking.
Kingdom: The highest category into which organisms
are classified.
Class: Split organisms by major characteristics
(vertebrates/ exoskeleton /etc.
Order: is based on similarities of physical traits
Family: is based on similarities that are shared
Genus: Differentiate from others of the same family
Species: A group of similar individuals that can breed
and produce offspring.
Classify by arranging labels in the correct order
Kingdom
Animalia
Genus
Mammalia
Family
Felidae
Class
Chordata
Species
Carnivora

What is my scientific name?
Answer :
Leo
Kingdom, Animalia (animals); Phylum, Chordata (vertebrate animals); Class, Mammalia (mammals); Order, Carnivora (meat eaters); Family, Felidae (all cats); Genus, Panthera (great cats); Species, leo (lions).
Okay, let’s look on a bigger scale
Kingdoms fall under a larger group called domains.
There are three domains used in classification.
1. Eukarya – All eukaryotic species
2. Bacteria - prokaryote
3. Archaea – prokaryote
Common ancestor of all organisms
