1. Classification

2. Scientists of all nationalities have agreed to use Scientific names for species.
Scientific names use the binomial system (Genus species)
There is a hierarchy of taxa from domain to species.
A classification group (normally) contains all the species that have evolved from a common ancestor.
Classification
Helps to identify species and
Helps identify characteristics shared by all species within a group.

3. The hierarchy of taxa There are three Domains Eukaryote Eubacteria

4. Binomial Nomenclature
Sometimes new evidence causes
scientists to move a species from one group into another.
I grouped plants according to how many anthers they had. This has completely changed.
Scientists still use my system of binomial nomenclature.
Every species has a latinised name
composed of:
it’s Genus (with a capital letter) and its species (without a capital letter)
Carl von Linné - (1707–1778), a Swedish botanist, invented the modern system of binomial nomenclature. Biologists have given him a Latin name = Carolus Linnaeus

5. Scientific classification of the Dog Flea
This is a simple illustration of the classification of a single species.
Each taxonomic group contains fewer species as you go down the table.
