Faunal and environmental change in the late Miocene Siwaliks of northern Pakistan
Abstract The Siwalik formations of northern Pakistan consist of deposits of ancient rivers that existed throughout the early Miocene through the late Pliocene. The formations are highly fossiliferous…
A new hominid from the Upper Miocene of Chad, Central Africa
The discovery of six hominid specimens from Chad, central Africa, 2,500 km from the East African Rift Valley, suggest that the earliest members of the hominids clade were more widely distributed than has been thought, and that the divergence between the human and chimpanzee lineages was earlier than indicated by most molecular studies.

This new find from Chad documents the presence of an early hominid a considerable distance, 2,500 km, west of the Rift Valley, which is most similar in morphology to Australopithecus afarensis.
A 16-Ma record of paleodiet using carbon and oxygen isotopes in fossil teeth from Pakistan
New material of the earliest hominid from the Upper Miocene of Chad
New dental and mandibular specimens from three Toros-Menalla fossiliferous localities of the same age are described, including a lower canine consistent with a non-honing C/P3 complex, post-canine teeth with primitive root morphology and intermediate radial enamel thickness, which confirm the morphological differences between S. tchadensis and African apes.

The large-bodied hominoid from Uganda dates to at least 20.6 million years ago and thus represents the oldest known hominoids sharing these derived characters with living apes and humans.

Overall, Morotopithecus is reconstructed as an arboreal species that probably relied on forelimb-dominated, deliberate and vertical climbing, suspension and quadrupedalism and may be the only well-documented African Miocene hominoid with a close relationship to living apes and humans.

Data is presented on intraspecific variation in the axial postcranial skeleton of some Primates, including hominoids (apes and humans), and hypotheses presented to explain the changes in terms of developmental genetics are presented.
Homoplasy and earlyHomo: an analysis of the evolutionary relationships ofH. habilissensu stricto andH. rudolfensis
A cladistic analysis of 48 of the most commonly-used cranial characters from recent studies of Pliocene hominid phylogeny and which distinguish two taxa within H. habilis sensu latos suggests that these fossils have different evolutionary affinities.

Evidence is shown for long-term climatic forcing of vegetation structure and mammalian ecological diversity at the subcontinental scale and for three patterns of response to climate change.
