6. 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

7. 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.

8. 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?

9. 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

10. 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.

11. The 6-Kingdoms Archaebacteria Eubacteria Protista Fungi Plantae Animalia You should identify the main characteristics of each.

12. 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!!!!!!!

13. 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

14. 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

15. Test Topics (DK, K, R) Early classification Schemes Aristotle and Linnaeus Modern classification scheme Methods of classification Dichotomous keys Cladograms and Phylogenetic Trees Constructing Cladograms based on amino acid sequence

16. 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?
