What Is Life?
Life Comes From Life
Francesco
Redi
designed one of the
first controlled
experiments. In his
experiment, Redi
showed that flies do
not spontaneously
arise from decaying
meat.

What is taxonomy?
Taxonomy
is the branch
of biology concerned with
the grouping and naming
of organisms
Biologists
who study this
are called taxonomists
Why classify?
To
To
help us study the earth
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 confusion
It is always written in the
Latin Language
Genus…
A
genus consists of a group
of closely related species
Other animals in the Canis
group include dogs and
coyotes
The genus name is always
Capitalized
Species...
A
species consists of animals
that can mate and produce
fertile offspring
Only wolves are known as
lupus.
The species name is always
lowercase
An animal is known by
two names…
Canis
lupus is the scientific
name for a gray wolf.
Canis is the genus name
lupus is the species name
This system uses a binomial
nomenclature
Binomial Nomenclature
Bi
means two
Nomen means name
A binomial nomenclature
is a classification system
using two names to
identify an organism
Who is Carolus Linnaeus?
Carolus
Linnaeus was a Swedish botanist
Developed a 8-level (taxa) classification
system based on similarities between
organisms
Aristotle and Classification

Many hundreds of years
before Linnaeus, a
Greek scholar named
Aristotle developed a
classification system for
animals. Aristotle first
divided animals into
those he considered to
have blood and those
he did not. This graph
shows Aristotle’s
classification system for
“animals with blood.”

Inferring:

In Aristotle’s
classification, where
would a cow be
classified? A whale?

Predicting:

Would Aristotle’s
classification system be
used today? Explain.

How does it work?
There
are 6 broad kingdoms
Every 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)

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)
