If those conditions are not met, then the evidence is either inconsistent with the hypothesis, or ambiguous.

Other criteria (habitat preference, population density, direct and indirect evidence of dietary breadth related to incisor use) are only consistent with the hypothesis under certain conditions.

The unique characters of DOA are explainable by this raw material factor, rather than technological development of hominids.

The inclusion of new raw material, chert, for toolmaking in the following Developed Oldowan A (DOA, 1.65-1.53 m.y.a.) facilitated more distinctive and variable flaking strategies depending on the kind of raw materials.

Our interpretation of the fauna, the archeometric results, and the magnetostratigraphy of Sterkfontein indicate that it is unlikely that any Members yet described from Sterkfontein are in excess of 3.04 Ma in age. We analysed the enamel extension rate in Homo antecessor (8 teeth analysed), Homo heidelbergensis (106), Homo neanderthalensis ('Neanderthals'; 146) and Upper Palaeolithic-Mesolithic Homo sapiens (100). Department of Anatomy and Anthropology, Sackler Faculty of Medicine, Tel Aviv University, Tel Aviv 69978, Israel. METHOD OF STUDY: Literature in human evolution, genetics and reproduction.

Specifically, the hominin fossil commonly referred to as the "Little Foot" skeleton from Member 2, which is arguably the most complete early hominin skeleton yet discovered, has been magnetostratigraphically dated to 3.30-3.33 Ma (Partridge [2000] The Cenozoic of Southern Africa, Oxford: Oxford Monographs, p. [2000a], The Cenozoic of Southern Africa, Oxford: Oxford Monographs, p. More recent claims suggest that hominin fossils from the Jacovec Cavern are even older, being dated to approximately 3.5 Ma. Dental growth can be determined from the speed of enamel formation (or extension rate).

Four is the minimum number of individuals represented by the postcranial remains recovered up to now.

In terms of pattern, AMHS crania are uniquely characterized by two general structural autapomorphies: facial retraction and neurocranial globularity.

(AH) and to test hypotheses about the changes in cranial development that underlie the origin of modern human cranial form.

Ecological models that may explain the evolution of eurytopy in early hominins are discussed. The Bed I Oldowan (1.87-1.75 m.y.a.) is characterized by the least effort strategy in terms of raw material exploitation and tool production.

Researchers will need to explore other avenues of research in order to generate testable hypotheses about the demise of Paranthropus.
