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!)
