purpose of this lab is for you to outline general primate traits and compare and contrast physical (morphological), physiological (functional), and behavioral traits in humans and non-human primates.
Workstation 1: Mammal vs. PrimateInstructions:
Observe the skull traits and the relative size of different parts of the skull in the three mammals below–a cat, a black bear, and a macaque (a type of Old World monkey).
Explain three traits that differentiate the primate from the two non-primates. Explain means you must do more than list. For example, do not write “the teeth”. Please be specific and descriptive.

Workstation 2: Is it a Primate?Instructions:
Observe the 3D models below (Sample A, Sample B).
Decide if the model is depicting a primate based on your observations. If it is not a primate, explain why it is not (e.g., what trait(s) tell you it is not a primate?). If it is a primate, explain why it is (e.g., what trait(s) tell you it is a primate?)

Workstation 3: Strepsirrhini vs. HaplorhiniInstructions:
Observe the 3D model of the potto skull below.
List three Strepsirrhini traits you observe. The traits must be distinguishing features of the Strepsirrhini primates and not found in the Haplorhini primates.

This 3D skull above is from a potto. The picture below is a potto. <\/p>\n
Observe the 3D model of the chacma baboon skull below.
List two Haplorhini traits you observe. The traits must be distinguishing features of the Haplorhini primates and not found in the Strepsirrhini primates.

This 3D skull above is from a chacma baboon. The picture below is a chacma baboon. <\/p>\n
Observe the 3D model of the mystery primate skull below.
Is this mystery primate a Strepsirrhini or a Haplorhini? Explain how you arrived at your answer.

Workstation 4: Anthropoids–Platyrrhini (New World monkeys) vs. Catarrhini (Old World monkeys, apes, and humans) Observe the 3D models below (Sample A, Sample B).
What is the dental formula in each sample
Describe the molar morphology (especially the cusps) in Sample A and in Sample B. Which sample has bilophodont molars?
Based on your observations, which sample is a platyrrhine and which sample is a catarrhine?

Workstation 5: Hominoids Apes and humans are classified as hominoids. The partial classification of hominoids is as follows:
Order: Primates
Suborder: Haplorhini
Infraorder: Anthropoidea
Parvorder: Catarrhini
Superfamily Hominoidea
Instructions:
Observe the chimpanzee skull below.
Identify (name or list) two observable traits that make the chimpanzee a Haplorhini primate rather than a Strepsirrhini primate. For example, do not write “canine teeth” or “two orbits for the eyes” because these traits do not distinguish Haplorhini primates from other groups of primates. Identify (name or list) one observable trait that makes the chimpanzee a Catarrhini primate rather than a Platyrrhini primate.
Identify (name or list) two anatomical\/morphological traits that make the chimpanzee a hominoid (a member of the Superfamily Hominoidea). All hominoids should have the two anatomical\/morphological traits you list.
