HOW WILL YOU REMEMBER THE ORDER????
Carolus Linnaeus : 1732, came up with the universal 2 word-naming system called _____________________________
based on the dead language called LATIN. Each organism has a _____________ and _____________________ name.
_________________ is written first and is _________________________. Can be underlined or italicized but not both.
________________ is written second and is _______________________. Can be underlined or italicized but not both.

Scientific names can tell scientists how closely related organisms are to each other.
Based on their names, you know that the baboons
Papio annubis and Papio cynocephalus do not belong
to the same:
a. Family
b. Genus
The bullfrog, Rana catesbeiana, is most closely related
to the _____________.
c. Order
d. Species
a. Spotted chorus frog, Pseudacris clarki

Cladograms
Background: Cladistics is the study of evolutionary classification. Cladograms show evolutionary relationships
among organisms. Comparative morphology investigates characteristics for homology and analogy to
determine which organisms share a recent common ancestor. A cladogram will begin by grouping organisms
based on a characteristics displayed by ALL the members of the group. Subsequently, the larger group will
contain increasingly smaller groups that share the traits of the groups before them. However, they also
exhibit distinct changes as the new species evolve. Further, molecular evidence from genes which rarely
mutate can provide molecular clocks that tell us how long ago organisms diverged, unlocking the secrets of
organisms that may have similar convergent morphology but do not share a recent common ancestor.
Questions:
1. Which organisms in the cladogram in the diagram above have fur and mammary glands?
2. Which organisms in the cladogram in figure 1 have jaws?
3. Based on the cladogram in figure 1, which shared a common ancestor most recently – a mouse and a
lizard or a mouse and a perch?
4. Which two organisms would you expect to have a closer matching DNA sequence for a gene that is
NOT under selective pressure in nature – Hagfish and Pigeon or Hagfish and Salamander?

SELF-QUIZ:
1.
What structure is common to all domains of living organisms?
A DNA
B Nucleus

D mode of reproduction.
4.
A table of animal characteristics is provided below:
Rodents, such as mice, have a notochord, hair, 3 inner ear bones, and produce milk. They have five
toes on each foot. Rodents, therefore, are classified as –

A allows scientists to classify organisms and assign each living thing a universally accepted name.
B makes certain that all future discoveries of organisms will fit into an existing category.
C prevents different countries from using their own languages for common names of organisms.
D provides a way to ensure that species will no longer change over time.
