2. Significance of Classification
Helps to systematically organise the
diversity of organisms.
Helps to determine the relation between
organisms
Helps to trace the possible origins of
organisms
Helps to identify the great variety of living
things
3. What is Taxonomic order?
One common way of
classifying living things is
based in the Linnaeus
System of classification
which puts organisms into
Taxonomic Groups that
indicate their natural
relationships.
4. Eight Taxonomic Groups
Living things are
placed into the eight
taxonomic groups:
Domain, Kingdom,
Phylum, Class,
Order, Family, Genus
and Species based on
certain similarities
5. Diversity of Humans
Humans are a
species of
Homo
Sapiens and
are divided
into the
following:
6. DOMAIN
A domain is the top level
grouping of organism.
Organisms are classified
according to cellular
characteristics. Each
domain consists of a
number of kingdoms like
plant and animal
kingdom.
7. KINGDOM
A kingdom is the second
level of grouping. A
group of similar
kingdom forms a
domain. A kingdom
contains one or more
phylum.
8. Phylum
A phylum (division)
is a taxonomic
group of related or
similar organisms.
Each phylum
consists of a number
of classes.
9. Class
A class contains one
or more orders. A
group of similar
classes forms a
Division.
10. Order
An order contains one or
more families like
carnivore, omnivore
etc. A group of similar
orders forms a class.
11. Family
A family contains one
or more genera (plural
of genus). A group of
similar families forms
an order.
A family may be
divided in subfamilies.
12. Genus
The genus is a grouping
of similar and closely
related species.
The scientific name for
man is ‘Homo sapiens’
which means ‘wise man.
Modern man belongs to
genus Homo. The first
part reflects the genus.
This system is used to
name living thing.
13. Species
The two part naming
system (mentioned
in above section) is
used to name living
thing.
The second part of
the name sapiens
identifies the
species.
