The origin of Australopithecus, the genus widely interpreted as ancestral to Homo, is a central problem in human evolutionary studies. Australopithecus species differ markedly from extant African apes and candidate ancestral hominids such as Ardipithecus, Orrorin and Sahelanthropus. The earliest described Australopithecus species is Au. anamensis, the probable chronospecies ancestor of Au. afarensis. Here we describe newly discovered fossils from the Middle Awash study area that extend the… 

Earliest axial fossils from the genus Australopithecus.

Ardipithecus ramidus and the Paleobiology of Early Hominids

TLDR
Ardipithecus ramidus indicates that despite the genetic similarities of living humans and chimpanzees, the ancestor the authors last shared probably differed substantially from any extant African ape.

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

TLDR
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.

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

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

A new species of great ape from the late Miocene epoch in Ethiopia

TLDR
The combined evidence suggests that Chororapithecus may be a basal member of the gorilla clade, and that the latter exhibited some amount of adaptive and phyletic diversity at around 10–11 Myr ago.

The Evolutionary History of the Australopiths

TLDR
The australopiths were diverse, geographically widespread, and anatomically derived, they lived through periods of pronounced climate change, and their story dominates the narrative of human evolution for millions of years.

"Lucy" redux: a review of research on Australopithecus afarensis.

TLDR
The discovery and naming of A. afarensis coincided with important developments in theory and methodology in paleoanthropology; in addition, important fossil and genetic discoveries were changing expectations about hominin divergence dates from extant African apes.

New specimens and confirmation of an early age for Australopithecus anamensis

TLDR
Isotope dating confirms A.anamensis' intermediate age as being between those of Ardipithecus ramidus, and Australopithecus afarensis, and new specimens of maxilla, mandible and capitate show that this species is demonstrably more primitive than A.afarensis.

New discoveries of Australopithecus at Maka in Ethiopia

TLDR
The discovery of new fossils from Maka, dated to 3.4 Myr ago, provide powerful support for the interpretation of A. afarensis as a single, ecologically diverse, sexually dimorphic, bipedal Pliocene primate species whose known range encompassed Ethiopia and Tanzania.

Late Miocene hominids from the Middle Awash, Ethiopia

TLDR
New hominid specimens from the Middle Awash area of Ethiopia that date to 5.2–5.8 Myr and are associated with a wooded palaeoenvironment are reported, indicating that Ardipithecus was phylogenetically close to the common ancestor of chimpanzees and humans.

Early Pliocene hominids from Gona, Ethiopia

TLDR
New Early Pliocene hominid discoveries and their palaeoenvironmental context from the fossiliferous deposits of As Duma, Gona Western Margin (GWM), Afar, Ethiopia are reported.

Morphology of Australopithecus anamensis from Kanapoi and Allia Bay, Kenya.

TLDR
Based on the limited postcranial evidence available, A. anamensis appears to have been habitually bipedal, although it retained some primitive features of its upper limbs, and there appears to be no autapomorphies precluding A.Anamensis from ancestry of A. afarensis.

The new hominid species Australopithecus anamensis

TLDR
The material discovered so far displays primitive features along with more derived characteristics typical of later Australopithecus species, which suggests that A. anamensis belongs near the ancestry of this genus.

A new hominid from the Upper Miocene of Chad, Central Africa

TLDR
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.

The locomotor anatomy of Australopithecus afarensis.

TLDR
It is demonstrated that A. afarensis possessed anatomic characteristics that indicate a significant adaptation for movement in the trees, and it is speculated that earlier representatives of the A.Afarensis lineage will present not a combination of arboreal and bipedal traits, but rather the anatomy of a generalized ape.
