5. Biological Classification
Assign a universally accepted name to each organism (Latin)
2. Place organism into groups that have biological meaning
Based on similarities in structures mainly
Many scientist are pushing for a complete DNA grouping; more detailed/precise but a “closest gets more messy before it gets organized affect.”

6. 8th century – Carolus Linnaeus developed a naming system
System called binominal nomenclature; printing of the scientific name is the Genus & species.
Presentation is important!
Underline or italicized
Only the genus is capitalized.
Ex: Acer rubrum
These characteristics can be
placed into a dichotomous key,
a key to help others to identify
a species
13. The binomial system of classification was developed by:
A. Darwin
B. Wallace
C. Linnaeus
D. Malthus
10. In printing scientific names, it is conventional for only the ____ to be underlined or italicized.
A. Binomial
B. Genus
C. Species
D. Kingdom
Canis lupus familiaris
Genus species subspecies

8. The diagram shows a dichotomous key and a picture of a fruit
According to the key, the fruit comes from which species of tree?
Fraxinus americana
Fraxinus nigra
Acer platanoides
Acer negundo

9. Which is more closely related?
Use the visual above to answer the following:
Are bats or cats more closely related to the gray wolves?
Using what you can infer from the figure, what are characteristics of animals in the order Carnivora?

10. Cladogram
Cladogram: A hypothesized evolutionary tree that proposes how species may be related to each other through common ancestors.
Derived Characteristics:
Traits use to figure our evolutionary relationships
Traits shared by some species but are not present in others
The more closely related a species = more derived characteristics

Backbone  amniotic egg  hair  live young  placenta
Toad  Iguana  platypus  Kangaroo  Squirrel

11. HOW TO READ AN EVOLUTIONARY TREE
Fish Bird Human Rat Mouse
Common ancestor of mice and rats
Time
Common ancestor of mice, rats, and humans
Common ancestor of mice, rats, humans, and birds
Need to show if a rat is more closely related to a mouse or to a bird… easy… what about a human to a mouse or bird?
Point out the common ancestor and who it is closely related to. - TEST QUESTION
11. Which plant, shown in the cladogram below, did all the other plants shown evolve from:
  A. Spikemosses
B. Quillworts
C. Clubmosses
D. Flowering plants
southeastregionscienceconnection.weebly.com
Common ancestor of mice, rats, humans, birds, and fish
At this point, a speciation event occurred and the ancestral species split into two species. This shows which groups are closely related, not which ones are more primitive or advanced.

12. Various types of evolutionary trees
Why does DNA often have the “last word” when scientists are constructing evolutionary relationships?
No matter the style of tree, all represent possible evolutionary pathways of certain organisms and relationships.

2. The Florida Panther was once considered to be a subspecies of cougars and given a special trinomial taxonomy of Puma concolor coryi. Current scientists however, have studied the Florida Panther and removed the subspieces classification to only Puma concolor. Which of the following would most likely explain why the classification of the Florida Panther changed.
New genetic evidence suggests a much closer relationship between the Florida Panther and other cougars.
Shared features between the Florida Panther and other cougars were also found in newly discovered organisms in the world.
Advanced technologies have shown a large difference in cell structure between the Florida Panther and other cougars.
Trinomial naming conventions are no longer used by longer used by scientists because only the genus and species are important in taxonomy.

3. An analysis of DNA and RNA sequences can be used to classify organisms. A dendrogram, such as the one shown below, is based on molecular data. It can be used to represent evolutionary relationships within a group of organisms that are hypothesized to have descended from a common ancestor.
Which statement is best supported by the information in this dendrogram?
Lesser pandas are more genetically similar to giant pandas than they are to raccoons.
Brown bears are more genetically similar to giant pandas than they are to sun bears.
Lesser pandas are more genetically similar to raccoons than they are to giant pandas.
The bear species are all more genetically similar to dogs than they are to giant pandas.
