hominini
the tribe to which humans and our direct ancestors belong, who are referred to as hominins
modern humans and now-extinct human species
from about 7 mya on
not the same as hominoid (apes and humans)
species of hominins
sahelanthropus tchadensis
ardipithecus ramidus
australopithecus afarensis
paranthropus boisei
homo habilis
homo erectus
homo neanderthalensis
homo sapiens
sahelanthropus tchadensis
earliest
7-6mya
West/Central Africa
relatively small canine teeth
small brain (slightly smaller than modern chimps)
extremely limited evidence
ardipithecus ramidus
opposable big toe
4.4mya
East Africa
a more bowl-shaped pelvis allows for some bipedal walking, but also had features of a climbing ape
grasping, unarched foot more suitable for climbing
brain the same size as a modern chimp
australopithecus afarensis
3.8-2.1mya
East Africa
thick chewing muscles
large zygomatic arches
growth cycle closer to modern chimps than modern humans
short growth period
less time for socialization
smaller cranial capacity than genus homo
paranthropus boisei
2.3-1.3mya
East Africa
megadontia: having large molar teeth relative to body size
thickest tooth enamel among hominins
robust features - sagittal crest, massive zygomatic arches
the bigger the cheekbones (zygomatic arches) are, the more surface area for large chewing muscles to attach
the more muscle, the greater ability to chew tough/abrasive food like raw vegetation
chewing muscles run under the zygomatic arch to connect to the lower jaw
homo habilis
2.8-1.44mya
still only in Africa
looks a lot like Australopithecines
better at tree climbing than us
place in genus homo has been questioned bc of similarity to Australopithecines
associated w/ Olduwan tools, but NOT the first confirmed toolmakers among hominins
homo erectus
1.9-0.5mya
1st known migration of member of the genus homo outside of Africa and into Asia
longer legs, s-shaped spine, bipedal
adapts to a wider variety of landscapes than previous hominins
associated w/ Acheulean tools and fire
homo neanderthalensis
300,000-30,000ya
Europe and Western Asia
stockier and more robust than modern humans
at some point, there was interbreeding b/w neanderthals and modern humans
homo sapiens
AMH (anatomically modern humans)
300,000ya
bigger cranial capacity
smaller teeth
around the world in 1000s of years
skull features
sagittal crest
zygomatic arches
brow ridge
dentition
cranial capacity
foramen magnum
sagittal crest
a bony ridge on the top of the skull formed by strong chewing muscles
zygomatic arches
cheekbones
large cheekbones that flare to the side - sign of powerful chewing muscles
brow ridge
ridge above the eyes that indicates the position of the face on the skull, relative to the brain case
dentition
tooth size and dental palate/arcade
big molars - sign of eating fibrous vegetation
cranial capacity
head size (indicates brain size)
foramen magnum
the opening at the base of the skull where the spinal cord enters and connects to the brain
position tells us how the skull sits on the spinal column and if posture was upright or horizontal
shared characteristics
traits or structures that are shared by all or most species in a group bc they are inherited from a common ancestor
derived characteristics
traits unique to a species that evolved after 2+ species who have shared a common ancestor diverged
3 morphological characteristics that make humans unique
bipedalism
brains
teeth
advantages of bipedalism
arms/hands are free to carry objects
reach higher
better view
long distance walking/running
heat regulation
foot absorbs shock
performing ballet
disadvantages of bipedalism
back, knee pain
circulatory system works harder
painful birthing process
skeletal changes associated w/ bipedality
foramen magnum
lumbar lordosis
bowl-shaped pelvis
longer lower limbs
angled femur
widened tibial plateau
foot as a stable platform
skeletal changes associated w/ bipedality - foramen magnum
in humans, it is anterior (under the skull, towards the center/front) to balance the head on the upright body
skeletal changes associated w/ bipedality - lumbar lordosis
s-shaped curvature of the spine allows for the upper body to be stabilized over the hips and lower limbs
skeletal changes associated w/ bipedality - pelvis
shorter and broader iliac blades
a bowl-shaped pelvis in hominins has a stabilizing function
helps to hold up the internal organs
allows for bigger muscles to attach
allows for upright walking
skeletal changes associated w/ bipedality - angled femur
inward-angled femur brings support of the lower limbs under the body/center of mass
skeletal changes associated w/ bipedality - wide tibial plateau
the place where the tibia meets the femur at the knee is broad enough to disperse force and acts as a shock absorber
skeletal changes associated w/ bipedality - foot
there is a platform for upright walking
the arch absorbs shock
this means that our big toes are smaller and don’t grasp
basic differences b/w chimp and human dentition
smaller canines
reduced shearing complex
shorter, wider jaws
diastema: a gap b/w the canines and adjacent teeth for the canine on the lower jaw
Why are hominin fossil so rare?
fossilization: when hard tissues (bone, teeth) slowly turn to stone and keep their shape
the fossil record is extremely limited
the conditions for making fossils is very specific
traits of australopithecines
large zygomatic arches (thick chewing muscles)
smaller cranial capacity than genus homo
bipedal - had anterior foramen magnum
more bowl-shaped pelvis than a chimp
big toe was in line w/ the rest of the toes (helps w/ bipedal walking)
Lucy
adult female Australopithecus Afarensis
3.2mya
discovered in Hadar, Ethiopia
significant portion of the skeleton
47/207 of bones
might’ve fallen out of a tree, but we don’t know
features of Lucy’s skeleton that made her bipedal
has anterior foramen magnum
like Ardipithecus Ramidus - more bowl-shaped pelvis than a chimp
unlike Ardipithecus Ramidus - big toe was in line w/ the rest of her toes to help w/ bipedal walking
Laetoli footprints
from Tanzania (East Africa)
about 3.6mya
footprints of australopithecines
one foot slightly in front of the other
shows a balanced stride and a pattern of walking
split into lineages (paranthropus vs. homo)
genus homo emerges from one of the australopithecine lineages 3-2mya, going a different direction from the robust australopithecines (genus paranthropus)
genus homo is associated w/ larger brains and the making and use of stone tools
Why do later hominins lose their fur?
humans are the only mammals that do not have fur
evolution of bipedalism - more ideal running body
allowed homo erectus to hunt using persistence hunting (chasing prey until it collapses from exhaustion)
no water break needed
persistence hunting lead to the risk of overheating
hominids w/ less fur could sweat more efficiently and cool down w/o having to take breaks in the shade and lose valuable hunting time
locomotion is connected to our loss of thick fur
What are the benefits of fire to hominins?
warmth for survival in cold climates
hominins can reasonably live in a wider range of climate
cooking food allows for a wider variety of foods to be consumed and makes it easier to chew, affecting chewing muscles
kills the parasites in meat during the process of cooking
neanderthals to know
Shanidar 1
Shanidar 3
La Chapelle-Aux-Saints 1
Shanidar 1
a male that lived into his 40s or 50s
b/w 35 and 50yo
missing hand
withered arm
fractured skull
fracture to the left side of his eye socket, which might have caused blindness or brain injury
he had bony growths in his ear canals, which probably impacted his hearing
he survived many years, around 2 decades, after the injuries were inflicted
strong evidence for neanderthals helping to care for one another and living in groups
looking after vulnerable community members = compassion
Shanidar 3
a male in his early 40s
probably broke/sprained his right ankle, which healed
ended up w/ bony spurs and degenerative joint disease in the ankle that caused him pain and limited his mobillity
has a groove on the top edge of the left 9th rib, which is evidence of a wound deep enough to have potentially collapsed his lung
La Chapelle-Aux-Saints 1
“The Old Man of La Chapelle”
erroneously framed as hunched
primitive caveman
b/w 25 and 35yo or older than 40yo
Svante Pääbo’s sequencing of the neanderthal genome
b/w 1-4% of neanderthal DNA has been incorporated w/ the DNA of some modern humans
neanderthal DNA could have been initially beneficial to modern humans, but is not beneficial today
if neanderthals and anatomically modern humans could produce viable offspring, our definition of species is called into question
genetic relationship b/w neanderthals and anatomically modern humans
two separate species that are still able to interbreed and produce viable offspring
DON’T think of them as the same species just bc they interbreed
What happened to neanderthals when they met AMH?
lived concurrently, some interbred and some fought
interbreeding and violent confrontation
JUST GUESSES - AMH are more cognitively advanced than neanderthals, climate change
we do NOT know why neanderthals declined and how AMH persisted
3 models of human origins
Recent African Origin Model
Multiregional Evolution Model
Multiple Dispersals Model
Recent African Origin Model
modern humans arose as a new species in Africa b/w 200,000 and 180,00ya
Multiregional Evolution Model
modern humans are only the most recent version of a single species, homo sapiens, that has been in Africa, Asia, and Europe for at least 2 million years
Multiple Dispersals Model
incorporates complexities in genetic datasets to argue that humans left Africa in multiple waves
tools to know
Olduwan
Acheulean
Mousterian
blade
Olduwan
core becomes tool
the core stone hits another stone (hammerstone) to create flakes
flakes have a sharp edge
etic term/given to the type of tool by anthropologists
associated w/ homo habilis
Acheulean
more symmetrical than olduwan tools
bifacial flaking produces a handaxe
better edges
follow predetermined forms
more varied in style
more complicated to make
flake pattern has to be more consistent
associated w/ homo erectus
Mousterian
flake become tool
different tools for different tasks (shows some specialization of tools)
Levallois technique
Levallois technique
flake-tool manufacture
flake is what become the tool, not the core
requires a lot of prep, but yields a higher quality tool
hammerstone prepares the core to make a specific kind of flake
a tortoise-shell shaped flake that has an acute angle
blade
a stone flake that is at least 2x as long as it is wide
an example of growing specialization of tools
based on the size of the core
core maintenance + core being used to create multiple tools
different blades serve different purposes
can also be used to make a scraper
tool specialization
the manufacture of special tools for a particular job
corresponds to more environments to adapt to as humans spread out across the globe and greater access to nutrition
some tools could have helped w/ clothing production (needles)
creative expression
an expansion in variety of stone and bone tools, adornment, abstract carving
symbolic expression - cave at Lascaux
20,000yo
France
paintings are painted on the walls of the cave
mostly images of animals
not sure what was used to paint the images (finger, spit?) and also how the images were painted (fire inside cave?)
storytelling
definitive evidence of humans rendering the human body artistically
symbolic expression - Venus figurines
sculptures from 20-25,000ya are also of women
ex. Venus of Willendorf from Austria and Venus of Brassempouy from France
Central Europe
there is a lot of emphasis on head, breasts, hips, thighs
Venus of Willendorf
a small female figurine/sculpture
found in 1908 in a village in Austria
11 cm tall
dates from about 25,000ya
no feet, very thin arms rested on top of her breasts, a reed hat
symmetrical
meant to be held
no context
other sculptures from the same period are also of women
Venus of Willendorf - Why do they call her “Venus”?
given the name of the goddess of love
assigning meaning as a goddess figure
fertility
prevailing modern cultural norms assume that nude women are renderings of Venus
artifact
an object made or modified by humans
a collection of meanings, relationships, cultural processes
materiality
having the quality of being physical or material
the objects made and used in any society combine to form its material culture
site
locations where evidence of past life and materials can be discerned
habitation site
places where people lived at some point in the past
archaeological methods
excavation
aerial/satellite survey
ground survey/surface collection
remote sensing
test pits
GIS
visual documentation
ground survey and surface collection
wide regional surveys can identify specific areas where an excavation should take place
ground survey - dividing a specific area into a grid pattern, walking over the area, collecting any artifacts that are exposed
walking an area can give archaeologists perspective on the landscape features and any places where concentrations of artifacts are more dense
remote sensing
produces pictures/schematics of a site
gives a fuller picture of a site than an excavation can allow
disturbs the site less than excavating
good way to preserve and figure the nuances of the site
test pit
a small excavation (a square of a meter or less) that is a preliminary way to assess artifacts below the surface of the ground, and if a fuller excavation is necessary
allow archaeologists to note stratigraphy
stratigraphy
layers of deposits
excavation
if test pits reveal artifacts or features, then archaeologists may choose to move forward w/ excavation of larger units (trenches)
detailed notes and photographs are taken throughout
artifacts are tagged and catalogued
feature
an attribute found in an excavation that was formed, created, or modified by humans
visual documentation
digital photography of the excavation process
artifacts in situ (in the place where the artifact was found)
after conservation/cleaning, recognizing that the process of excavation permanently destroys the original context
allows for reconsultability
GIS (geographical info systems)
laborious
can produce highly detailed digital maps for systematic analyses of sites and regions
What does it mean that archaeology is a destructive science?
excavation will permanently alter a context
those conditions can never be replicated
this doesn’t mean “don’t dig”
it means that both careful planning and thorough documentation are needed when excavation is occurring
How should we look at material objects?
easy to think about an object either in terms of its physical properties (dimensions, what it’s made of) or its aesthetic qualities (as art)
we should deepen and complicate these processes of understanding further
we put meanings to things based on our own cultural perceptions
Why do objects in museums have cards beside them?
familiarization of the object
defamiliarization of the object
constraints/guardrails on meanings - gives a functional or artistic interpretation and is not in situ/context
3 ways objects change
material change
meaning change
“hands” change
material change
the form or the use changes over generations
an individual object wears out/is modified
technical/style changes in the type of item
meaning change
the broader social significance changes due to a changing context
new or changing tech can have impacts on existing tech
“hands” change
an individual object passes into different hands and the significance/meaning changes
when a functional object is placed in a museum, its meaning changes bc of how it is being displayed and who it is being exhibited to
ethics of excavations, display, storage
questions of ownership
“Shouldn’t the people whose direct ancestors made or used these objects have some rights over these collections?”
“Who has has the moral right to display and interpret them?”
“Who has the right to say what significance they held?”
“Do the museums that own these objects have the right to say whatever they want about another culture’s objects, or should the people from whom the objects were collected have a say?”
Slack Farm (1987)
MS habitation site near the OH river in what is now KY, which included over 1000 Native American graves
after paying $10,000 for land rights to dig, looters desecrated the site
dug up the site
scattered skeletons and grave goods
led to publicity and public outrage
public outrage contributed to several legislative changes at the state and federal levels
changes for the greater protection of graves and of archaeological sites more generally
NAGPRA (Native American Graves and Repatriation Act) (1990)
law that established the ownership of human remains, grave goods, and important cultural objects as belonging to the Native Americans whose ancestors once owned the
repatriation
consultation w/ descendants
increased transparency in which institutions inform tribal rep’s of their holdings
can lead to petitions for the repatriation of objects
caveat - NAGPRA only covers materials from groups w/in the geographic bounds of the US even though Native American boundaries also included places in Canada and Mexico
repatriation
the return of human remains or cultural artifacts to the communities of descendants of the people to whom they originally belonged
modes of subsistence
the social relationships and practices necessary for procuring, producing, and distributing food
correlations are associations that correspond w/ a particular mode of subsistence (usually present but not guaranteed)
Neolithic revolution
when humans began to produce their food (growing crops and raising animals) rather than relying exclusively on foraging
hunting → food production (cultivating, farming, herding)
sometime around 10,000ya - plant and animal domestication practices develop independently in several areas
ramifications of food production, sedentism, agriculture
development of cities (monumental architecture)
writing
changing/limited diets
public health and epidemic diseases
social inequality
rise in war and human bondage
harder work
environmental problems
ramification - development of cities
city: a relatively large and permanent settlement, usually w/ a population of at least several 1000 inhabitants
more people = bigger workforce
monumental architecture
ex. Mohenjo Daro
ramification - writing
begins in Mesopotamia around 5,600ya
allows for storage, flow, retention of info
played a key role in economic life, interpersonal communication, literature and poetry
ex. Complaint Tablet to Ea-Nasir (3,700yo)
ramification - changing/limited diets
diets tend to rely on a small number of plant/animals species
diets based on crops are generally less varied, less nutritious, less healthful
trade-off - crop yields are more reliable and larger
ramification - public health and epidemic diseases
sedentary, dense populations allow diseases to spread more easily and stay longer in a population
increased need for sanitation in areas where people are packed together (not always met)
potential for disease to jump from animals to humans when they are living together closely
ramification - social inequality
public property → inequality
evidence of both poverty and social inequality in certain contexts
resources are not shared, but owned
egalitarianism often gives way to more elaborate systems of stratification
relatively less stratification and sharing → unequal access to wealth and power
hereditary succession keeps power in certain lineages, smaller numbers of people control resources
ex. large mortuary architecture in Egyptian pyramids (multiple people working to honor an individual), King Tut (ornate tomb that includes extravagant wealth, but he wasn’t a memorable king bc he was young when he died)
ramification - war and human bondage
property → conflict over property, resources, territory
social stratification and inequality gives way to greater distinctions → slavery and other forms of human bondage
ramification - harder work
greater demands for labor to maintain systems of food production
greater modification of land for more intensive agricultural practices
ex. Inca terrace farming at Moray

terrance farming at the Inca site of Moray
adapts land that is not otherwise suitable for agricultural production
stone retaining walls forming terraces that absorb sunlight to protect crops from frost
crucible effect - kept the center of the depressions warm, allowed for different crops to be grown than what could be grown at high altitudes
ex. tomatoes, pumpkins, tobacco, etc.
making their warm weather conditions at a high elevation allowed for healthier and more diverse diet
What does terrace farming allow?
different crops can be grown than what could be grown at high altitudes → healthier and more diverse diet
ramification - environmental problems
degradation of land
pollution
decrease in biodiversity
sedentism
year-round settlement in a particular place
effects of sedentism
permanent dwelling and storage
people tend plants and herd animals in the same place over and over again, making domestication easier
permanent demarcation of land and resources leads to private property
mass storage of items in pits/baskets (ceramics and pottery)
ceramics for aesthetics
