CLASSIFICATION Prior Knowledge What is a species? Why are dogs
and cats in different species? Group Activity: paper and pencil Go
to your lab group. Take off one of your shoes. Group shoes
according to characteristics. ex. athletic, dress
Slide 2
CLASSIFICATION SHOES Athletic DressCasual Every shoe should be
described individually with the persons name it belongs to.
Slide 3
SHOE CLASSIFICATION How did you first classify the shoes? As
the groups got bigger, did the divisions change? What are some
other things that are categorized or organized into classes or
groups? ex. grocery stores

Slide 5
Naming Organisms Why do we need to name organisms? What is the
name of this organism? Why do scientist not want to use common
names?
Slide 6
The common name of many animals can be misleading. Ceylon
frogmouth (Batrachostomus moniliger) is a bird. Killer whales
(Orcinus orca ) are not whales, but dolphins.
Slide 7
Flying fish (Parezocoetus mesogaster) do not fly, but glide.
Galliwasp (Diploglassus lessorae) is not a wasp but a lizard.
Slide 8
Why do scientist not use common names? Confusing more than one
common name Misleading starfish is not a fish Why use a scientific
name? There is only one scientific name Felis concolor Classifying

Slide 9
Read pg. 300 - 304 What language is used for the scientific
naming? Latin ex. "E Pluribus Unum = one out of many or of many,
oneE Pluribus Unum Since 1873, the law requires that this motto
appear on one side of every United States coin that is minted. What
are the 2 parts of the scientific name? Genus (Latin for group)
species general description exact kind organisms share a major only
1 kind of organism characteristicwithin a genus Scientific
Name
Slide 10
Species name = describes the appearance or distribution of an
organism. Taxonomy : Science of the naming and classifying
organisms.

Recognizing Relationships Tell me something about each of these
organisms. Carnegiea gigantea Nymphaea odorata Canis familiaris
Peromyscus californicus Viola tricolor giant saguaro cactus
fragrant water lily domestic dog common California mouse three
color pansy
Slide 12
Genus + species names should be used when referring to an
organism. Species name alone is not enough. Drosophila melanogaster
is a fruit fly. Thamnophis melanogaster is a garter snake.
Slide 13
What is the correct way to write the scientific name?
drosophila melanogaster Drosophila melanogaster D. melanogaster Why
are scientific names in Latin? 1.The language does not change.
2.Its tradition. Universal 3.Dont have to rename millions of
species. Read pg. 301 * Always capitalize the Genus and not the
species.

He improved the system of naming plants and animals by a two
word name to identify the genus and species. binomial nomenclature
Carolus Linnaeus (1707 1778), a Swedish botanist whose original
name was Carl von Linne.
Slide 15
Matter of Fact: How many species are there ? No one really
knows how many species exist. Estimates of the total number of
species vary from 3 - 30 million to 10 100 million, depending on
the source. Taxonomists estimate that only 1.5 to 1.8 million
species have been identified, but there are no central archives.

Read pg. 305 - SPECIES What is the definition of a biological
species? A group of natural populations that are interbreeding or
that could interbreed, and that are reproductively isolated from
other such groups. Hybrids result of interbreeding by individuals
of different species usually infertile. * Usually artificially
brought about. mare + male donkey = mule Bengal cat = domesticated
cat + Asian Leopard cat
