Biological Taxonomy

  • There are at least 50 common names for
  • the animal shown on the previous 2 slides.
  • Common names vary according to region.
  • Soooo……why use a scientific name?
    • 1. unique identifier for everything
    • 2. everything fits into the whole
slide4

Biological Taxonomy

  • We only know about a tiny fraction of the
  • organisms that exist or have existed on Earth.
  • Taxonomists give a unique scientific name to each species they know about whether it’s alive today or extinct.
  • The scientific name comes from one of two
  • “dead” languages – Latin or ancient Greek.
  • Why use a dead language?
  • Every organism fits into a tree of life that has levels of organization ending with most specific.
slide5

Life is everywhere on this planet in amazing

variety: how do you make sense of it all?

slide6

Making sense of life: The tree of life

  • All living organisms are related
  • The tree is a picture of how everything relates
  • Different branches on the tree represent different groups
  • This is a very simple version, the tree really looks more like this…
organizing life history
Organizing life:History
  • Aristotle 2000 years ago. Organized organisms by visible features and where they live 1) plants and animals 2) where each thing lives-- in ocean or on land
  • Linneaus in the 1700’s. Swedish, he invented two name system, father of taxonomy. Still using physical characteristics, just more specific.
  • Evolutionary biologists say the tree relationships should reflect organisms common evolution. For example: Linneaus put bats with birds, because they both fly. Evolution says bats are mammals and are therefore closer to humans, dogs and cows.
  • DNA biochemistry changes some relationships, confirms others. Platypus is and example.
  • Today Tree of Life Web Project

Tree of Life Web Project
  • All of life is being described and organized
  • The relationships of different living things is being confirmed by modern methods (DNA, Biochemistry)
  • It is a world wide cooperative project
  • Huge and ambitious
slide9

a two name system for writing scientific names.

  • The genus name is written first (always Capitalized).
  • The species name is written second (never capitalized).
  • Both words are italicized if typed or underlined if hand written.
  • Example: Felis concolor or F. concolor
  • Which is the genus? The species?

Binomial Nomenclature: two names

slide10

Now we have a name so

where does each organism fit?

Kingdoms: most general

Genus: very specific

Species: just that one kind

So for every

organism

That exists

on the planet

There is an exact place

In the tree.

King Philip Came Over For Good Soup helps you remember.

slide14

Big circle represents kingdom, next phylum, next class etc. Is A or B

Correct?

vvv

A

B

Kingdom phylum class order family genus species

slide15

The levels are like nested boxes or circles. Biggest is kingdom,

next class etc. Is A or B Correct?
