Anthropology Exam #1 Flashcards
What is a primate?
Mammals (2 types):
- Monotremes (lay eggs)
- Therians (live birth)
What are 3 major categories of traits useful in characterizing the primate order?
- Morphological Traits
- Life History/Patterns
- Sociability & Flexibility
What is Primate Pattern?
> Set of Traits
>General Tendencies
State 3 Morphological Traits.
- Hands & Feet
- Dentition
- Senses & the Brain
Name Hands & Feet characteristics.
> 5 digits (fingers)
Prehensility
Opposable Thumb
Nails not claws
What is Prehensility?
The ability to grasp.
What does “opposable” mean?
Operates independently.
Name two types of grips.
- Power Grip
2. Precision Grip
What does it mean to have a prehensile tail?
Can grip/grasp with tail.
Name Dentition characteristics.
> Retained primitive dental characteristics
>Reduced number of teeth
What are primitive dental characteristics?
4 types of teeth: incisors, canines, premolars, & molars.
What is a “tooth comb” an example of?
A specialization; this is a primitive trait in species.
What is the dental formula?
The number of each kind of tooth is given for one-quarter of the mouth.
What is the dental formula for a general mammal?
3.1.4.3
What is the dental formula for a human?
2.1.2.3
What are 4 features of the category of Senses & the Brain?
- Enhanced Vision
- Color Vision
- Olfaction
- Expanded Primitive Brains
Describe the components that contribute to a primates enhanced vision.
Forward facing eyes + overlapping fields of vision = stereoscopic vision.
What does stereoscopic vision contribute to?
Depth perception
What is a post-orbital bar? (describe)
A bony ring around the eye.
What type of vision do most primates have?
Color vision
What is color vision?
The ability to differentiate different wavelengths of light.
Name & describe 3 types of views (hint: -chromatic)
- Monochromatic: no greens, blues, or reds.
- Dichromatic: only blues & greens
- Trichromatic: blues, greens, and reds.
What is the most common view amongst mammals?
Dichromatic
What are opsins?
Color receptors in the eyes located on the surface of the cones in the retina of the eye.
What does the retina contain that allows for vision?
Photoreceptors (cones & rods)
Which of the two, cones or rods, contain opsins?
Cones (allow for color vision).
What types of view do the following demographics have?
- Monkeys in Africa/Asia
- Apes & Humans
- Monkeys in the Americas
- Diurnal Lemurs
- Nocturnals
- Trichromatic
- Trichromatic
- Di- and Trichromatic
- Dichromatic
- Monochromatic
What are advantages of seeing in color?
Can pick up on visual cues, and better forage.
What is the advantage of dichromatic vision?
> Breaking the color camouflage
>not distracted by colors
What is olfaction?
The action or capacity of smelling; the sense of smell. (less important)
Are primate olfactory structures larger or smaller in primates?
Smaller
Describe primates’ brain size in relation to body size.
Primates have larger brains relative to body size.
Name the parts of the brain (primates).
Brain stem, cerebellum, cerebral cortex.
What is the brain stem responsible for?
Physiological Functions
What is the Cerebral Cortex responsible for?
interpretation, memory, & thought.
What are Life History Patterns?
traits associated with the biological life cycle.
What are 4 traits of the Life History Patterns?
A. Longer gestation period
B. Reduced number of offspring
C. Longer infant dependency
D. Longer lifespan (45+ years)
In regards to Primate Patterns, describe sociality & flexibility.
> highly social, live in a social group
> flexible to environmental change
Who studies primates?
> anatomists
biologists/zoologists
psychologists
anthropologists (only since 1950’s)
What does Anthropology split into?
> Biological Anthropology
>Sociocultural/archaeology/linguistic anthropology
What is primatology a subsection of?
Biological Anthropology
Why study non-human Primates?
To better understand human biological evolution.
State 3 goals of anthropological primatology.
- Elucidate humans’ origins using a comparative approach
- Human/Non-human primate interfacing (interacting)
- Applied primatology
Define ethnoprimatology.
ecological/cultural interconnectedness across time & space.
In regards to elucidating human origins using a comparative approach, what are some points of comparison?
> Anatomy/Physiology/Behavior
How similar/different
Human Uniqueness
Describe Applied Primatology.
Study behavior–>informs captive management conservation efforts.
What are 2 major research settings in which anthropologists study primates? Give examples.
- Captive Settings ex. zoos, laboratories.
2. Field Settings ex. native habitats, free ranging.
List advantages of a captive setting.
- controlled environment
- increased observability
- ability to manipulate subjects/environment
- kinship records
> amenable to cognitive tasks & social behavior/kin
What is the disadvantage of captive settings?
Not typically able to observe what the subjects are truly capable of.
What topics are typically studied in captive settings?
Psychology & Biology
What topics are typically studied in field settings?
Ecology, feeding, and ranging.
List 2 advantages of field settings.
- High Generalizability
2. More typical behavior
List 3 disadvantages of field settings.
- Low observability
- Observer presence
- Logistical issues
Define Taxonomy.
Means of organizing/ordering biological diversity via a series of commonly accepted names for organisms.
What system do we use to name organisms, and who developed it? What two components make up the name?
Binomial Nomenclature, developed by Carolus Linnaeus. Name is the genus + the species.
What are examples of human-primate interface?
Ethnoprimatology, roadside monkeys, provisioning.
Define Anthropolgy.
The study of humanity/ human behavior.
What is Anthropological Primatology?
The study of non-human primates; a subfield of Anthropology.
Why are primatologists ditching the terms “New World” and “Old World” when describing the geographical location of monkeys?
The terms have traces to its colonialism in its background.
How do primates move about their environment (locomotion)?
> Quadrupedalism
>Arboreal Quadrupeds >Suspensory Locomotion
