Questions Pre-assessment
Instructions:
• Read each question carefully and do the
following:
– Identify the concept being tested by the
question
– Put the question in your own words
– Ask the question a different way
– Answer the question
Classification Quiz
• The steps of the classification scheme, in
order, are:
• Who has more in common, organisms in the
same Family or in the same order?
• Members in the same Class must also
belong to the same (Phylum, Genus, or
Order)
• A group of related classes is:
• Write your name as if it were a scientific
name.
Notes on Classification
• Taxonomy=The science of Classification
• Taxonomy has always been of interest to
people trying to understand the natural
world
• Aristotle-1st classification scheme which
had 2 groups-plants and animals. Each
group also had a subgroup based on where
they lived.
• What are the problems with this scheme?
Carl von Linnae
• Swedish aristocrat-very interested in plants and
had A LOT of time on his hands.
• Became not only interested in classifying, but
also in a common naming system that anyone
could understand.
• Came up with Binomial Nomenclature (Bi=2,
Nom=Name, clature=system-you can do the
rest) using Latin Names
• Became a celebrity-his house is still a tourist
attraction.
• Because of his fame and love for latin,
changed his name to Carolus Linnaeus
How does Binomial
Nomenclature work?
• Modern classification uses KPCOFGS (you
know what these are;-)
• The Scientific, Binomial name, is simply
the last two names from the classification
scheme written as follows:
• Genus species or sometimes: G. species
• Notice, the first name is ALWAYS
capitalized, and the last is ALWAYS lower
case. Also, the whole thing is italicized OR
underlined.
The 6-Kingdoms
•
•
•
•
•
•
•
Archaebacteria
Eubacteria
Protista
Fungi
Plantae
Animalia
You should identify the main characteristics
of each.
Modern Classification Example
•
•
•
•
•
•
Kingdom: Animalia
Phylum: Chordata
Class: Mammalia
Order: Primates
Family: Hominidae
Genus: Homo (notice the italics and
capitalization!)
• Species: sapiens
• Guess the mystery animal!!!!!!!
Modern Classification
• The overall goal of classification is to
determine evolutionary relationships and
group closely-related individuals
• This used to be accomplished using
characteristics, however, since times have
changed, we now examine DNA to find
relationships
Cladograms and Phylogenetic
trees
• Cladogram-.graphic representation of the
evolutionary relationships between species.
Different from a phylogenetic tree in that each
split only branches into two (bifurcation), and
based on a derived character.
• Phylogenetic Tree-graphic representation of a
classification system based on evolutionary
relationships and when things evolved.
• See overhead for examples

Self-evaluation
• Figure out your score without extra credit and
compare it to your score with. Are you
surprised at the difference? Why or why not?
• Did you actually use your study plan to
prepare for this test? If so, do you think that
you need to change it? How?
• Thinking about your quiz scores for this past
unit, would you say that you improved on
this test?
• What will you do next time to improve your
grade or keep a good grade?
