Dental topography and diets of Australopithecus afarensis and early Homo.
Diet is key to understanding the paleoecology of early hominins. We know little about the diets of these fossil taxa, however, in part because of a limited fossil record, and in part because of limitations in methods available to infer their feeding adaptations. This paper applies a new method, dental topographic analysis, to the inference of diet from fossil hominin teeth. This approach uses l...
متن کاملPatterns of dental development in Homo, Australopithecus, Pan, and Gorilla.
Smith ([1986] Nature 323:327-330) distinguished patterns of development of teeth of juvenile fossil hominids as being "more like humans" or "more like apes" based on statistical similarity to group standards. Here, this central tendency discrimination (CTD) is tested for its ability to recognize ape and human patterns of dental development in 789 subadult hominoids. Tooth development of a moder...
متن کاملMating Behavior in Australopithecus and Early Homo: A Review of The Diagnostic Potential of Dental Dimorphism
Dental dimorphism is one of the primary means by which the mating systems of extinct hominins are studied. Its use has been particularly significant for describing the behaviors of Australopithecus and early Homo, and consequently the factors involved in the evolution of our own species. Analysis however, has tended to produce ambiguous and contrasting results, with no firm agreement as to what...
متن کاملHomo floresiensis: microcephalic, pygmoid, Australopithecus, or Homo?
The remarkable partial adult skeleton (LB1) excavated from Liang Bua cave on the island of Flores, Indonesia, has been attributed to a new species, Homo floresiensis, based upon a unique mosaic of primitive and derived features compared to any other hominin. The announcement precipitated widespread interest, and attention quickly focused on its possible affinities. LB1 is a small-bodied hominin...
متن کاملDental development in Homo naledi
Humans' prolonged somatic development and life history are unique among primates, yet their evolutionary origins remain unclear. Dental development has been used as a proxy to reconstruct life history evolution in the hominin clade and indicates a recent emergence of the human developmental pattern. Here, we analyse tooth formation and eruption in two developing dentitions of Homo naledi, a lat...
