What makes humans unique compared to other species
large brains (highly intelligent), bipedal, reliance on culture
epoch
a period of time in history or a person’s life, typically one marked by notable events or particular characteristics.
epochs in order, fossil apes to hominids
oligocene (25mya), myocene (23-5 mya), pliocene (5-2.5 mya), pleistocene (2.6 mya-11.7kya)
oligocene
25mya
divergence of monkeys and apes (in dentition for example)
myocene
23-5mya number and diversity of apes expands throughout africa to europe and asia
-40 genera of apes
today we have just 3 genera and 4 species
pliocene
5-2.5mya
- forests replaced by grasslands led to extinction of most apes
- important speces existed still
pleistocene
- 6mya to 11.7kya
- abundance ofthe genus Homo
Hominins
directly involved in modern human evolution
- bipedalism as defining characteristic
- adaptability to the changing mosaic environment
Sahelanthropus tchadensis
in myocene
- 6-7 mya
- fossil info based on cranium
- v flat face unlike the great apes but like humans
- BUT brain was more like a human than an ape
- position of foramen magnum suggests bipedalism
Ardipithecus ramidus (Ardi)
- 4 mya
- pelvis and foramen magnum suggest bipedalism
- ardi appears to be human like
- ape-like feet
Australopithecus
a genus -4.17-~2mya -more human-like bones than previous genera/species -Australopithecus afarensis--Lucy -Fully upright hominin -Modern feet -Similar pelvic configuration to humans -Cranial is still very ape-like -Cranial capacity around chimp size o One third the size of human avg -Prognathic features o Forward thrusting lower face o Similar to great apes -tool use!
the genus Homo
appears around 2.8mya (pliocene)
- homo habilis–the earliest Homo species
- -flatter face
- -steeper forehead
- -larger brain 700cc abt half of human average
Premodern or archaic Homo sapiens
• 600kya
• come from Africa spread to Europe and S asia
-uses levallois stone tool industry–shaped flakees from prepared cores–use of stone tools in hunting
Anatomically modern humans
- 200kya
- evolved in Africa and nowhere else
- migrated elsewhere
- between 150-100kya migration out of Africa
- encountered neadertals with some interbreeding
- aurignation stone tools
- chattelperronian tools
- these are incredibly sophisticated stone tools
neandertals??
- now considered a group of premodern humans
- 130kya to 40kya
- probably descendants of earlier homo species that migrated
- possibly from homo erectus
Neanderthal culture
• Mousterian tools
o Refinement of levallois technique
o Dozens of task specific tools
• Subsistence
o Meat
Similar to contemporary carnivores at the time
Gathering of plants still occurred
• Burials
o Evidence for compassion
o Care for individuals with trauma
Like blind, or with lost limb but they still have lived a long life so they are clearly caring about these people
o Symbolic expression through burial goods
• Are they related to modern humans? Dow have neandertal DNA
o For some groups, yes
The upper paleolithic
• 50kya-10kya • complex and elaborate lithic technology • abundance of non-utilitarian objects • much more elaborate burials • larger sites o populations would come together in a yearly cycle o nomadic but with seasonal strategies logistical collecting
Early Art
• petroglyphs—designs etched into rock faces
• parietal art—art on a wall such as paintings
• mobilary art—portable
Earliest ceramics were figurines • venus figurines • 35-20kya • depicts women of all shapes and sizes, all ages, and all states of fertility • they represent women in any stage
peopling of the New World
arrived through the Bering strait
- from russia to alaska
- the most common answer to how humans arrived in the New World (the Americas)
- SEE ARTICLE
the key stone ages
paleolithic, mesolithic, neolithic
paleolithic
distinguished by the earliest stone tools
from homo habilis to end of pleistocene
mesolithic
proliferation of regional adaptations and local cultural diversity
o In the New World it is called the archaic period
o At the end of the pleistocene and early Holocene
neolithic
after 12kya when domestication of plants and animals replaced foraging as dominant means of subsistence
mesolithic cultural characteristics and geographic differences
o Shift in subsistence focus due to extinction or unavailability
o Diversity in environment corresponded to a diversity in cultural adaptations
Diversity in artifacts settlement patterns and subsistence strategies
o General change in subsistence from megafauna to smaller animals fish shellfish and birds
As well as reliance on plant foods previously absent
o Encouraged a shift from nomadic existence to a more sedentary one in some regions
Paleoethnobotany (PEB)
the study of how past humans interacted with and used plants that is through time and across space!
-microbotanicals and microbotanicals
Macrobotanicals
botanical remains that can be seen with the naked eye
Often examined with a microscope
• study charred plant remains bc they preserve morphological traits and we can infer human interaction
• something else here
How do we recover charred macrobotanicals
• through flotation
o accompanied by processual archaeology
