DO: Today we will learn about the history of
classification
DQ: Why do we have a classification
system?
WHAT IS
CLASSIFICATION?
CLASSIFICATION IS grouping things
according to similar characteristics (Examples
of characteristics are size, shape, color,
behavior, etc…)
Biological classification systems name &
organize living things in a logical and
meaningful way.
DEFINITIONS
Taxonomy: the study or practice of
classifying living things
Basis of a classification/taxonomic
system: the characteristic that is used
to decide what things are placed in
which groups during the process of
classification
History of Classification
1) Aristotle:
A. Lived around the year of 384 BC
B. Designed a classification system for organisms
1. The basis of his taxonomic system was the characteristic
of movement.
2. First: He divided ALL living things into two
groups/kingdoms:
Those that can move
from place to place
ANIMALS
Those that cannot move
from place to place
PLANTS
3. Second: He divided the group called animals
(can move) into 3 groups according to the way
they moved: fly, walk, swim
History of Classification
2) Today’s system:
– A. Basis of today’s system: similarity of structure
(ex.: skin covering, DNA)
– B. The system used today has 5 kingdoms. Listed
from the kingdom of the simplest organisms to the
kingdom of the most complex organisms, these 5
kingdoms are:
1) Moneran Kingdom (simplest organisms)
2) Protist Kingdom
3) Fungi Kingdom
4) Plant Kingdom
5) Animal Kingdom (most complex organisms)

Classification – definitions – Part A
1) unicellular: made of one cell
2) multicellular: made of more than one
cell
3) autotroph: an organism that gets its
energy by making its food in its body
4) heterotroph: an organism that gets its
energy by eating other organisms
