Classification of Life
Christopherson
Group the
beads in the
bag on your
desk.
Briefly explain
how your
categorized
them in your
notes

Method by which biologists group and
categorize organisms.
What is Taxonomy?
Science of Classification
History of Classification: Aristotle
Grouped all living things
into two main groups:
Plants and Animals

Aristotle's view of
life was
hierarchical;
creatures could be
grouped in order
from lowest to
highest, with the
human species
being the highest.

Wake-up
1. How did scientific names get “out of hand”
during the Exploration Era?
2. According to Aristotle, group animals
together. For example, in your notes
yesterday, a bird, bat and butterfly were
together.
Carlos Linnaeus
Father of Taxonomy
Developed a
system for
universal system
for naming
organisms:
Binomial
Nomenclature
Binomial Nomenclature
Each organism is named using two Latin
descriptive words:
1. Genus: Group of closely related species
2. Species: Group of interbreeding organisms.

Rules for Binomial Nomenclature
1. Capitalize the
Genus and the
species is lower
case
2. Underline or
italicize both
genus and
species

rubrum. Write this correctly using binomial
nomenclature.
2. List the seven levels of taxonomic
organization from most specific to broades.
