CLASSIFICATIONPrior 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

SHOES

Casual

Dress

Athletic

Every shoe should be described individually with the person’s name it belongs to.

shoe classification
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

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?

slide6

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.

slide7

Flying fish (Parezocoetus mesogaster) do not fly, but glide.

Galliwasp (Diploglassus lessorae) is not a wasp but a lizard.

slide8

Classifying Living Things NOTES:

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

slide9

Read pg. 300 - 304

Scientific Name

What language is used for the scientific naming?

Latinex. "E Pluribus Unum“ = “one out of many or of many, one”

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

characteristic within a genus

slide10

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
Recognizing Relationships Tell me something about each of these organisms.

giant saguaro cactus

fragrant water lily

domestic dog

common California mouse

three color pansy

Carnegiea gigantea

Nymphaea odorata

Canis familiaris

Peromyscus californicus

Viola tricolor

genus species names should be used when referring to an organism species name alone is not enough
Genus + speciesnames 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.

Read pg. 301

What is the correct way to write the scientific name?

drosophila melanogaster

Drosophila melanogaster

Drosophilamelanogaster

D. melanogaster

* Always capitalize the Genus and not the species.

Why are scientific names in Latin?

  • The language does not change.
  • It’s tradition. Universal
  • Don’t have to rename millions of species.
slide14

Carolus Linnaeus (1707‑1778), a Swedish botanist whose original name was Carl von Linne.

He improved the system of naming plants and animals by a two‑word name to identify the genus and species.

“binomial nomenclature”

matter of fact how many species are there
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.

7 Classification Groups

Kingdom - Phylum - Class -Order -Family -Genus –Species -

county city

street house

slide18

To help you remember the seven classification groups in order, remember this sentence:

Kingdom

Phylum

Class

Order

Family

Genus

Species

slide19

Notice how 1 Kingdom will have many phyla.

A phylum will have many classes…

One Kingdom will have 1000’s of species in it.

Mammalia

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 – usuallyinfertile.

* Usually artificially brought about.
