AUSTRALOPITHECINE LIFEWAYS
- Africa- 4-1.2 mya
- Woodland environment
- Bipedal but still spend some times in trees
- No language
- Subsistence (dentition)
- Gathering plants, seeds, berries, nuts, and grasses
- Maybe small game- rats,
lizards, hares, etc
- Ardipithecus & Australopithecines afarensis,
gracile and robust
- A. garhi scavenged larger game
- Stone Tools w/ A. garhi
WHY BIPEDALISM?
- Scavenging- requires Long periods of walking
(endurance)
- Aid in seeing potential food and predators
- Feeding on nuts and seeds requires standing
- Carry away spoils of find
THE END OF AUSTRALOPITHECINES
THE FIRST OF OUR GENUS
THE LEAKEY LUCK
- Louis
- Miocene haplorhini, H.erectus
- Mary-
- A. boisei, A. afarensis, Laetoli footprints, H.
habilis, homebases?,
- Richard-
- H. habilis
- Meave-
- A. anamensis
Homo habilis
- Handy man
- 1964-Louis Leakey
- 2.4-1.8 mya
- Earliest sites
- Koobi For a, Kenya
- Lower Omo, Ethiopia
- Sterkfontein, South Africa
- Oldowan
- First member of genus Homo
- Contemporary with Robust Australopithecines
Homo habilis
- Larger cranial
capacity than Australopiths
- 631 cc average
(500-800 cc range)
- Larger brain but no
increase in body size
- larger front teeth,
somewhat smaller molars than Australopiths
OLDOWAN TOOL TRADITION
- FIRST ARCHAEOLOGICAL CULTURE
"PALEOLITHIC"
(divided into Lower, Middle, Upper)
- Oldowan = Lower Paleolithic
OLDOWAN TRADITION
- Eastern Africa
- 1.8 mya
- Locally available materials
- Different Raw Materials
- Omo, Ethiopia (quartz pebbles)
- Koobi For a, Kenya (basalt and quartzite)
- Olduvai Gorge, Tanzania (basalt and quartzite)
OLDOWAN TOOL TYPES
Types of Oldowan Sites
- Sites with Stone Tools Only
- Sites with Stone Tools and Bones of One Animal = "Kill"
or "Butchery" Site
- Sites with Stone Tools and Bones of Many Animals = "Living
Site", "Home Base" or "Central Place"
Hunting vs. Scavenging Debate
Lewis Leakey
Big Game hunters
R. Blumenshine, L.
Binford, P. Shipman
-scavenging
-broken
bones
FLK North
Olduvai Gorge, Tanzania
- "Kill or "Butchery" Site
Sites with stone tools and bones of 1 animal
- Extinct Elephant (Deinotherium)
bones
- Striations and cut marks on the bones
DK
Living Site
Olduvai Gorge, Tanzania
- Sites with Stone Tools and Bones of Many Animals
- Circle of stones- possible wall for a structure
Food Sharing and Glynn Isaac
•
Scavenging,
but sharing food (Koobi Fora
and FLK sites)
•
Provides
economic stability
•
Females
could stay at home with their children
•
Development
of language
•
Reciprocal
obligation
•
Marriage
patterns and division of labor
Lewis Binford
and “Uncle Wilbur”
•
Binford argues against the DK site as a living site and FLK
as a kill site
•
Problems according to Binford
–
Scavengers, not hunters
–
Lake shores are dangerous
–
Death of animals over
time
–
Low intelligence
–
No evidence for social
organization
Death Sites in Modern Savannas vs Olduvai Sites
•
Low bone concentrations
–
Olduvai 3-214 times greater
•
Little mixing of bones
from different animals
–
Olduvai high numbers of mixing
•
Low ecological
diversity
–
Olduvai high ecological diversity
•
Vertebrae and other
axial skeletal parts remain near the site and limb bones tend to be removed
–
Olduvai – small
frequency of axial elements to limb bones
•
Catastrophic mortality
(drought or flood) leave diagnostic geologic evidence
–
Olduvai low articulated skeletons
Robust Australopiths v. Homo
- Clearly two separate adaptations
- robust Australopiths fitting hypervegetarian niche
- Homo habilis fitting niche of meat scavenging, foraging
omnivore
The end of
Homo habilis
- Oldowan tools
- Home bases
- Scavenging
HOMO ERGASTER
- Earliest appearance in East Africa
- 1.8-1.7 mya
- East Turkana
- Nariokotome/West Lake Turkana
- Specimens from east Africa not as buttressed in
the skull (brow, nucal) as Asian forms
- Also have thinner cranial bones
- and with Acheulian
technology
- Differences are sufficient, some argue,
that the African speci-mens ought to be
designated as separate species, Homo ergaster
Nariokotome, West Turkana, Kenya
- WT 15,000 - most complete H. ergaster fossil skeleton ever found (1984-85)
- 12-year-old boy whose 5 ft. 3 in. stature
would have reached more than 6 ft. at maturity
- Life span 20-30, compared to 15-20 for australopiths
- Bergman’s Rule-Adaptation to
tropical environment
- postcranial remains similar to modern
humans
- Small pelvis and hence birth canal
BRAIN CAPACITY
- Significant increase in brain size from habilis
- 900 cc
- At birth estimates 200 cc to fit through birth
canal
- Intensification of infant care necessary
- Family units
ACHEULIAN
- Lower Paleolithic
- Acheulian
- 1.6- 200,000 ya
- Chert and obsidian tools
- Bifacial-flake removal on both sides of
the tool
- hand-axes, cleavers- pear shaped
- bifaces found throughout Africa and late in Europe show remarkable
similarity
TOOL PREPARATION
- two-stage process
- blank preparation
with hammerstone
- Refined with a softer
stone or antler
- shaping and thinning
on edges
- required good raw material, foresight,
and planning
- reflects (symbolic?) communication of
method and form
Handaxe Function
- Experimental Archaeology
- Elephants died of natural causes
- Cutting
- Sawing
- Scraping
Homo ergaster capable of Big Game Hunting, or
still just Scavenging?
BIG GAME HUNTING
- Olorgesaile, Kenya
- dates to ca. 800,000 BP
- Acheulian hand axes
- over 400
- Over 1 ton of stone material transported
to the site
- Preferred high quality material-chert and obsidian
- Closest sources 43-48 km rather than
local sources of quarzite
HUNTING
- Theory
- Hunted by Encircling Troop at night
- now-extinct giant baboon
- 44 adult and ~15 juveniles
- Bone type distribution
- Broken long bones
- Also remains of Antelope & Hippo
EARLIEST FIRE
- Koobi Fora, Kenya
- 1.6 mya fireplace
- Residue mixture of burned trees and grass species
- Phytoliths-microscopic bits of silica produced in plant cells
- Mostly palm wood burns easily
- 2,000 stone tools/160 chert tools burned-
used to start fire?
OUT OF AFRICA
- Intelligence
- Control of fire
- Environmental fluctuations- lower sea levels allowed travel to SE Asia
