Additional Anthropology Flashcards

 


 

Cards

Term
Subspecies
Definition
Shared geographic range of species, different phenotypic traits
Term
Population
Definition
Geographically seperated subset of species (term varies within question)
Term
Anthropometry
Definition
the study of sizes and measures of the human body
Term
Population Genetics
Definition
Genetic varation within and between groups of organisms
Term
Cline
Definition
gradual change in visible characteristic from one population to the next
Term
Fixed
Definition
When something is no longer polymorphic (having more than one form)
Term
Under what circumstances will alleles vary?
Definition
If there are at least two forms, the allele frequency is greater than one percent, and the trait is polymorphic
Term
Epipyseal Fusion
Definition
caps at the ends of bones fuse together at certain ages thus giving us something to gauge how old a person was when they died. Cartilage will califie too.
Term
What sorts of bone changes does one undergo through age? (There are two mentioned in slides)
Definition
Loss of trabecular bone and osteon cones in cortical bone increase with age.
Term
What bone is measured to give a height?
Definition
Femur length. 2.38 (femur length) = 61.41 = height + - 3.27
Term
metatherians
Definition
no placenta
fetus crawls from reproductive tract to pouch and nipple
(marsupials)
Term
Prototherians
Definition
Platypus and enchida
Born from eggs, but nurse
Term
Eutherians
Definition
Placental mammals
Term
preadaptation
Definition
an organisms use of an atomical feature in a way unrelated to the features original function
Term
Has a fully enclosed eye orbit
Definition
the gibbon and most other primates
Term
has a postorbital bar line in the back of he eye orbit but does not fully enclose it
Definition
the lemur and prosimians
Term
Visual Predation Hypothesis
Definition
suggested that arboreal predatory behavior accounted for the grasping hands and feet, and particularly the increased visual overlap and brain size
Term
Arboreal Hypothesis
Definition
enhanced visual motor systems and cognitive elboration is from arboreal life
Term
Generalized Dental formula of primates
Definition
2 incisors, 1 canine 2-3 premolars, 3 molars
Term
Encephalization
Definition
an animals brain size is directly related to its intelligence level
Term
Extended Ontogeny
Definition
extended period of dependence allowing for primates to have more culture
Term
Diurnal
Definition
active in the daytime
Term
Three characteristics of prosimians
Definition
Primitive - mobile ears, higher reliance on smell (wet noses), smaller brains
Term
Differences in the uterus' of Prosimians and Anthropoids
Definition
Prosimian - uterus bicornis (two horns)
Anthropoid - Uterus simplex (simple)
Term
Three characteristics of prosimians, loridea
Definition
nocturnal, aboreal, largely solitary
Term
Three characteristics of prosimians, tasiers
Definition
arboreal, nocturnal, carnivorous
Term
Platyrrhines have how many premolars? Catarrhines have how many premolars?
Definition
Platyrrhines (new world) 3
Catarrhines (old world) 2
Term
In terms of ectotympanic bone...platyrrhines have a --- and catarrhines have a ---
Definition
Platyrrhines have a ring, Catarrhines have a tube
Term
Characteristics of Callitrchidaes (aka Tamarins and Marmosets)
Definition
small body, polyandry, typically twins, a diet of tree exudates, fruits, and insects, digital claws
Term
Loph
Definition
an enamel ridge connecting cusps on a tooths surface
Term
bilophodont
Definition
refers to lower molars, in old world monkeys, that have two ridges
Term
Y-5
Definition
Hominoids' pattern of lower molar cusps
Term
Which critter has a tooth comb
Definition
Lemur, baby.
Term
Anthropoids
Definition
The higher primates monkeys old world and new world, apes, and humans.
Term
Prehensile Tail
Definition
A tail that acts as a kind of hand for support in trees, common in New World Monkeys
Term
Species
Subspecies
Populaions
Individuals
Definition
Thats the way it works. This will end soon.
Term
Cephalic Index
Definition
Head width / head length * 100
Term
Haplotype
Definition
Combination of alleles
Term
symplesiomorphy
Definition
a trait which is shared (cladidistic) with a common ancestor
Term
apomorphy
Definition
derived trait
Term
Sinodonts
Definition
first two are winged incisors with shovel shape pattern of teething. Often found in Native Americans
Term
Sundadonts
Definition
the other type of teeth pattern ided
Term
Phylogeny
Definition
Evolutionary tree reflecting relatedness and divergence of taxonomic groups
Term
Lactose dissarcharide
Definition
the process of lactase breaking down to simple sugars in young mammals, lactace decreases with age
Term
Lactace production is the dominant allele, homozygotes and heterozygotes can digest lactose
Definition
Lactoce tolerance f ound in populations with long history of diary
Term
Human Leukocyte Antigen (HLA)
Definition
diverse genetic system of linked loci on chromosome 6, controls immune response. Thus at low levels in a populations processors of the alleles have a greater resistence to infectious diseases. At high levels in a population diseases encounter alleles enough to evolve counter strategies
Term
Hypoxia
Definition
Oxygen starvation. When this happens at high altitude it leads to increased heart rate and increased breathing
