Term
| _______________ (3.6MYA) and ______________ (4.1-3.9 MYA) are both found in East Africa |
|
Definition
| A. Afarensis (3.6) and A. Anamensis (4.1-3.9) |
|
|
Term
| Some anthropologists believe that A. afarensis and A. anamensis should not be placed in a separate species, because they resemble the later hominid species: |

Term
| A. Africanus live between ____ and _____ MYA |
|
Definition
|
|
Term
| Found in Chad and dated btwn. 3.5 and 3 MYA (also thought to be contemporary with A. Afarensis) |
|
Definition
|
|
Term
| Similar to A. Afarensis (3.6MYA) but with much larger teeth, found in Ethiopia and dating to about 2.5MYA |
|
Definition
|
|
Term
| Found in Kenya with a flat, human-like face but alongside other facial forms, suggesting a non-linear evolution |
|
Definition
| Kenyanthropus playtops (3.5-3MYA) |
|
|
Term
| A Robust Australopethicine with adaptions for heavy chewing and the largest teeth of any hominid, 2.2-1.2 MYA found in East Africa |
|
Definition
|
|
Term
| Australopithecus robustus |
|
Definition
| 2.0-1.0 MYA, S. Africa, foot bones indicate bipedalism |
|
|
Term
| Along with A. Robustus, another S. African Australopithecine (3.3-2.5 MYA) slightly higher brain to body size than A. afarensis; teeth & face less primative. Also more ape-like limb lengths than afarensis |
|
Definition
|
|
Term
|
Definition
| May be earlier robust australopithecine than boisei or robustus, perhaps ancestral to boisei |
|
|
Term
| So different from other Australopithecines and with larger brain capacities (490 cc to 530 cc), anthropologists sometimes put A. boisei and A. robustus under this category |
|
Definition
|
|
Term
| Found in Western Chad about 7 MYA, possibly bipedal intermediate btwn hominid/hominoid features (small brain, large brow ridges, wide face; but hominid-like canines and teeth) |
|
Definition
| Sahelanthropus tchadensis |
|
|
Term
| Possibly earliest hominid (5.8-6 MYA) if bipedal; found in W. Kenya |
|
Definition
|
|
Term
| Perhaps intermittently bipedal, a possible link between Miocene apes and australopithecines; found in Ethiopia and dated to 4.4 MYA |

Term
| __________ is roughly contemporary with homohabilis (2.4-1.6 MYA, E. Africa) |
|
Definition
|
|
Term
| 3 Traits used to define H. habilis as a transitional species |
|
Definition
| (1) Expanded cranial capacity (590-710 cc) (2) Reduced postcanine tooth size and (3) presence of a precision grip for tool-making |
|
|
Term
| First hominid outside of Africa (earlier African specimen sometimes considered Homo ergaster) |
|
Definition
|
|
Term
| Cranial capacity, and dentition of Homo erectus |
|
Definition
| 1000 cc and almost identical to modern humans (with larger cheek teeth and more robust mandible) |
|
|
Term
| Dates of homo erectus in Africa, China, and SE Asia (respectively) |
|
Definition
| 1.8-1.5 MYA, 500-200 KYA, 1.8MYA-50KYA |
