Leonard andHegmon (1987) compare a series of dental metrics of ‘Australopithecus afarensisJohanson, White, andCoppens, 1978’ with criteria for modern apes, to test the hypothesis that ‘A. afarensis’ represents a single species. They also compare the morphology of the lower third premolar. The dental breadth of ‘A. afarensis’ shows a wide range of variation, particularly in the lower third premolar morphology which displays greater variation than in modern apes—yet the study concludes that the…

“Australopithecus afarensis”: A composite species

TLDR
Leonard (1991) reiterates most of his original arguments for supporting “Australopithecus afarensis” as a single species, but disregards the principle of morphological equivalence by comparing the dental metrics and morphology of a hominid with those of species of the Pongidae, which do not correspond with the degree of variation in hominids.

Australopithecus afarensis and the single species hypothesis

  • W. Leonard

TLDR
The balance of the evidence at present indicates that the fossils from Laetoli and Hadar represent a single hominid species, A. afarensis.

A morphometric analysis of hominin teeth attributed to Australopithecus, Paranthropus and Homo

  • S. Dykes
  • Environmental Science, Geography
  • 2016
TLDR
The implication of this study is that, especially in the case of modern humans, great caution needs to be exercised in using extant species as analogues for assessing variability considered to be a result of sexual dimorphism in fossil hominin species.

A mathematical landmark-based method for measuring worn molars in hominoid systematics

TLDR
The results support the use of mathematical landmarks to enable the inclusion of worn molar teeth in dental studies so as to maximize sample sizes and restore balance between populations and/or sexes in hominoid systematic studies.

Evolution of P3 morphology in Australopithecus afarensis.

TLDR
The degree and patterning of variation of the 20 known A. afarensis P3s are examined, and a model of sexual differences in niche exploitation, with the females exploiting a more arboreal environment, would seem to be supported by both the dental and postcranial evidence.

The taxonomic status ofpraeanthropus africanus (primates: Pongidae) from the late pliocene of Eastern Africa

TLDR
The taxonPraeanthropus africanus (Weinert, 1950), represented by the Garusi maxilla, is valid and reinstated, and the morphological pattern is not that of a primitive hominid, but of a relatively generalized pongid.

TLDR
Computed 'intra' and 'inter' specific allometry coefficients from these data suggest that canine size will usually scale at a higher level than molar crown area, which is at most isometric, and not positively allometric with respect to body size.

Taxonomic status of the hominine cranium KNM-ER 1813 (primates: Homininae) from the Plio/Pleistocene of Koobi Fora

TLDR
The hominine cranium KNM-ER 1813, from the late Plio/Pleistocene of Koobi Fora, has been regarded recently by some authors as a female ofHomo habilis but reassessment of its cranial morphology, dental metrics, proportions, and a new detailed determination of its sex indicates that it is probably a male.

Revision of fossil hominid jaws from the plio/pleistocene of hadar, in ethiopia including a new species of the genusHomo (hominoidea: homininae)

  • 2006
TLDR
The assignment of fossil hominoid jaws from the Plio/Pleistocene of Hadar to a single genus,AustralopithecusDart, 1925, is a misnomer, and on the basis of their unique hominine dentition, they are reinterpreted as representing a new species, Homo antiquus nsp.

TLDR
Though significantly correlated, tooth size and body size variables are too weakly associated to permit accurate predictions from regression equations, and evolutionary implications of intraspecific dental allometry are discussed.
