Why is observation important when
classifying things?
scientist need to observe the characteristics of
organism in order to group them together based on
their similarities.
Classification: Is the process of grouping things based on their similarities.
Why do Scientists Classify?
To help us study the earth
To help us organize all the species we discover . . .
To give every species a name based on a standard method so scientists from different countries can talk about the same animal without confusionIt is always written in the Latin Language
o Biologist use classification to organize living things into groups so that the organisms are easier to study
Who is Carolus Linnaeus?
Carolus Linnaeus was a Swedish botanist
Developed a 8-level (taxa) classification system based on similarities between organisms
An organism is known by two names…
For example:
oCanis lupus is the scientific name for a gray wolf. oCanis is the genus nameolupus is the species nameoThis system uses a binomial nomenclature
The first word in an organism's scientific name is its genus
genus: is a classification grouping that contains similar, closely related organisms
The second word in a scientific name describes a distinctive feature of an organism
Together, the two words indicate a species
A species is a group of similar organisms that can mate with each other and produce offspring that can also mate and reproduce
Binomial Nomenclature
Bi means twoNomen means nameA binomial nomenclature is a classification system using two names to identify an organism

How does it work?There are 6 broad kingdomsEvery living thing that we know of fits into one of the six kingdoms
Each level gets more specific as fewer organisms fit into any one group
A Sample Classification The lion belongs to the following groups: Kingdom Animalia (includes all animals) Phylum Chordata (includes all vertebrate
animals, as well as some other more primitive ones)
Class Mammalia (includes all mammals) Order Carnivora (includes carnivorous
mammals, from bears to raccoons to harbor seals)
Family Felidae (includes all cats) Genus Panthera (includes the great roaring
cats: lions, tigers, jaguars, and leopards) Species leo (lions!)
