A newly discovered partial hominin foot skeleton from eastern Africa indicates the presence of more than one hominin locomotor adaptation at the beginning of the Late Pliocene epoch. Here we show that new pedal elements, dated to about 3.4 million years ago, belong to a species that does not match the contemporaneous Australopithecus afarensis in its morphology and inferred locomotor adaptations, but instead are more similar to the earlier Ardipithecus ramidus in possessing an opposable great… 

The Pliocene hominin diversity conundrum: Do more fossils mean less clarity?

A closer look at the currently available fossil evidence from Ethiopia, Kenya, and Chad indicates that Australopithecus afarensis was not the only hominin species during the middle Pliocene, and that there were other species clearly distinguishable from it by their locomotor adaptation and diet.

New species from Ethiopia further expands Middle Pliocene hominin diversity

The new species from Woranso–Mille shows that there were at least two contemporaneous hominin species living in the Afar region of Ethiopia between 3.3 and 3.5 million years ago, and further confirms early hom inin taxonomic diversity in eastern Africa during the Middle Pliocene epoch.

Fossil Hominins, the Bipedal Primates

Early hominin diversity and the emergence of the genus Homo.

It is now apparent that there was even more locomotor diversity and experimentation across hominins than previously thought, and with the discovery of taxa such as H. floresiensis and H. naledi, that diversity continues well into the genus Homo.

Human evolution: Those feet in ancient times

A fossil foot found in Ethiopia suggests that human ancestors that walked on two feet and also ably climbed trees existed until 3.4 million years ago, adding evidence for locomotor diversity during

Introduction to KSD-VP-1/1: The Earliest Adult Partial Skeleton of Australopithecus afarensis

This edited volume provides the taphonomy and paleoecology of the partial skeleton, as well as detailed comparative descriptions of the preserved elements of KSD-VP-1/1 and their implications for the understanding of early hominin paleobiology.

A 3.8-million-year-old hominin cranium from Woranso-Mille, Ethiopia

A nearly complete hominin cranium from Woranso-Mille (Ethiopia) that is date to 3.8 million years ago is described, providing the first glimpse of the entire craniofacial morphology of the earliest known members of the genus Australopithecus.

Evidence for habitual climbing in a Pleistocene hominin in South Africa

Evidence for habitual use of highly flexed hip postures, which could potentially indicate regular climbing in a South African hominin from Sterkfontein, which is either Paranthropus robustus or Homo, is shown.



New hominin genus from eastern Africa shows diverse middle Pliocene lineages

New fossils discovered west of Lake Turkana, Kenya, which differ markedly from those of contemporary A. afarensis point to an early diet-driven adaptive radiation, provide new insight on the association of hominin craniodental features, and have implications for the understanding of Plio–Pleistocene hom inin phylogeny.

An early Australopithecus afarensis postcranium from Woranso-Mille, Ethiopia

A large-bodied specimen is described that is well within the range of living Homo and substantially antedates A.L. 288–1, establishing that bipedality in Australopithecus was highly evolved and that thoracic form differed substantially from that of either extant African ape.

Sterkfontein member 2 foot bones of the oldest South African hominid.

Four articulating hominid foot bones have been recovered from Sterkfontein Member 2, near Johannesburg, South Africa, and provides the first evidence that bipedal hominids were in southern Africa more than 3.0 million years ago.

New hominid fossils from Woranso-Mille (Central Afar, Ethiopia) and taxonomy of early Australopithecus.

The Woranso-Mille hominids cannot be unequivocally assigned to either taxon due to their dental morphological intermediacy, but could be an indication that the Kanapoi, Allia Bay, and Asa Issie Au.

New Postcranial Fossils of Proconsul africanus and Proconsul nyanzae

Our understanding of early Miocene hominoid postcranial material has been built upon a fossil record that consists, for the most part, of unassociated fragments of different individuals from

Combining Prehension and Propulsion: The Foot of Ardipithecus ramidus

The last common ancestor of hominids and chimpanzees was therefore a careful climber that retained adaptations to above-branch plantigrady and would thus have been unique among known primates.

Phylogeny of early Australopithecus: new fossil evidence from the Woranso-Mille (central Afar, Ethiopia)

The Woranso-Mille hominids show that there is no compelling evidence to falsify the hypothesis of ‘chronospecies pair’ or ancestor–descendant relationship between Au.

The evolutionary context of the first hominins

The relationships among the living apes and modern humans have effectively been resolved, but it is much more difficult to locate fossil apes on the tree of life because shared skeletal morphology

Woody cover and hominin environments in the past 6 million years

It is shown that the fraction of woody cover in tropical ecosystems can be quantified using stable carbon isotopes in soils, and 13C/12C ratio data point to the prevalence of open environments at the majority of hominin fossil sites in eastern Africa over the past 6 million years.
