The Linnaean System of Classification
In the mid 1700's, he developed a 7-Level
Classification System based on similarities between
organisms
All organisms were classified as animals or plants
Levels of linnaean system
Kingdom : Animalia
phylum : Chordata
class : Mammalia
order : Carnivora
family :Canidae
genus :Canis
Species :Canis lupis

10. PUBLICATIONS
He published “SPECIES
PLANTARUM” in 1753 upon
which he classified about
5900 species of plants.
He published “SYSTEMMA
NATURAE” in 1758 which
contains classification of 4200
species of animals.

11. Linnaeus introduced Binomial
Nomenclature in 1758
In a binomial name , the first word
is called generic name or genus
name or genetic epithet & the
second word is called specific name
or species name or specific epithet.

12. Both these words are in Latin and
printed in italics and underlined
when typed or handwritten.
The generic name begins with a
capital letter and the specific
name with a small letter.

13. For example, the scientific name of man is Homo
sapiens,of which Homo is the generic name to
which the specific name sapiens belongs.
The scientific name of honey bee is Apis mellifera,of
which Apis is the generic name to which the specific
name is mellifera belongs
The name of a particular organism is scientifically same
all over the world.It is the most important advantage of
the use of binomial name (scientific name).

14. A quote showing his
love for plants is:
“If a tree
dies,plant another
in its place”
