Homo Habilis
Point for scavenging
There are other to get protein other than hunting that may not leave a mark
Confrontational Scavenging
actively seeking hunting, and confronting prey
Parts found of Dmanisi fossils
skulls, mandibles, postcranial remains.
Evidence for hunting
(Passive) Bones that show bite marks on top and then tool marks below
Early Homo Brain Morphology
- Average Cranial Capacity = 900cc
Three place tools are found
- Butchery sites (where they are used) -Quarrying sites (where they are manufactured) -Home base (combination of the two) (debatable)
3 components of Olduwan Industry
- Core - Flake Hammerstone
BOU UP
- Daka, Bouvir, - Middle Awash, Ethiopia -1.0 mya - skull vault and post cranial remains - 995 cc
KNM-ER 42700 (4) (Hint :Elsie, Ahmed, Turkey)
- Ileret ,(koobi Fora), East Turkana -1.5 mya -691 cc - maybe female
Early Homo changes (2)
- Increased in body size and robusticity - Changes in limb proportions increases encephalization (size and complexity of brain)
2 Specimen examples for Homo Rudolfensis record number
- KNM -ER 1470 - ER 1802
3 locations where Homo Rudolfensis was found (Hint: Jovin, turkey,Ahmed
- Kanopoi, East Tanzania -East Turkana - Koobi Foora
7 Characteristics for early Homo
- Larger, more rounded brain case -Face less projecting )flat and vertical -Smaller Teeth (no Canine fossa) -Modern day body porpotions - More efficient bipedialism - Parabolic arcade shaped jaw - Small to no supaorbital torus
Early Homo Scull Morphology (7)
- Low Forehead - Thick cranial bone - Nuchal Torus - Sagital Ridge - Fairly Large posterior teeth - Prominent superorbital torus - Pentagonal skull/shape
Famous Homo erectus (7)
- Nariokatome Boy, Turkana Boy: WT 15000 - 108 bones (90% complete) - Male -1.6mya -168cm -hips narrow -880 cc
OH 5 (6)
- Olduvai George, TZ - Very Robust - Largest browriges - walls of cranial bones -1067 cc - largest of all Africa H. erectus
Where other homo habilis where found (Hint: home, home, neighbour,neighbour) (Tool, Ahmed, Cave, Birhanu and Game of thrones)
- Olduvai Gorge, TZ -Koobi Fora , Kenya -Strerkfontein, SA -Hadar, Ethiopia
Differences between Homo Habilis and Homo Rudofensis
- Rudolfensis has a larger cranial capacity (775cc to 510cc) - Rudofensis has no browridges - Rudofensis has a large flat face and habilis has a small face - Rudofensis has large posterior teeth and habilis has small one
Early Homo Body Morphology (4)
- avenger stature - average body mass - high sexual dymorphisism -increase in robusticity of skeleton
6 characteristics of first Homo Habilis found
- larger brain -larger incisors - Premolars and molars long and narrow -canines large compared to premolars -Jaw overall smaller than Australopithicine - Modern hand and foot
Homo erectus traits of Dmanisi fossils (3)
- long, low braincase - wide skull base -sagittal keeling.
4 Differences between Homo habilis and Australopiths
- more gracile - larger front teeth relative to their molars and narrow premolars - Have no grasping ability for foot -larger cranial capacity
What do stones show us
- tools are adaptations to the environment. (Olduwan tools where make it easier to obtain protein) -Tools are made in one area and used in another. Shows that they were being carried, indicates premeditation and intention
Weird thing about the fossils found for Homo habilis
-Most fossil found are females and or Juvenile
KNM- ER 3733 (Hint last years turkey) (5)
-Oldest found in Africa - 1.8 mya -East Turkana - Older female - 848cc
2 types of scavenging
1. Confrontational 2. Passive
5 facts about later Hominins
1. More widely dispersed 2. Larger 3. Committed to terrestrial habitat 4. Used more sophisticated stone tools 5. May have eaten significant quantities of meat
How old is the first homo habilis fossil found
1.75 mya
Age range of the Dmanisi fossils
1.8-1.7 mya.
How old is Homo Rudolfensis, year range
1.95 mya - 1.44 mya
most complete skull from Dmanisi (D2700) has:
1.less robust & thinner brow ridges. 2.projecting lower face. 3.large upper canines. 4.small cranial capacity -600 cc.

Where was first homo habilis found
Olduvai Gorge, TZ
Early Stone Tool Industry, where the earliest stone tools were found
Olduwan Industry (named after Olduvai George)
KNM - ER- 42700
Smallest H. erectus skull found
Rudofensis theory that builds on weird fact about homo habilis
Some think that Rudofensis is actually the male version of Homo Habilis
Passive Scavenging
Take what is found and left over from other s
Spiltters thoughts on Homo Rudofensis
The Homo Rudofensis specimens are slightly different from Homo Habilis so some think it is a new species
