Most interpretations of early hominin phylogeny recognize a single early to middle Pliocene ancestral lineage, best represented by Australopithecus afarensis, which gave rise to a radiation of taxa in the late Pliocene. Here we report on new fossils discovered west of Lake Turkana, Kenya, which differ markedly from those of contemporary A. afarensis, indicating that hominin taxonomic diversity extended back, well into the middle Pliocene.

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

TLDR
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.

A new hominin foot from Ethiopia shows multiple Pliocene bipedal adaptations

TLDR
New pedal elements from a newly discovered partial hominin foot skeleton from eastern Africa show that new pedal elements belong to a species that does not match the contemporaneous Australopithecus afarensis in its morphology and inferred locomotor adaptations, but instead is more similar to the earlier Ardipithecus ramidus in possessing an opposable great toe.

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.

New species from Ethiopia further expands Middle Pliocene hominin diversity

TLDR
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.

An Asian perspective on early human dispersal from Africa

TLDR
It is shown here that it is time to develop alternatives to one of palaeoanthropology's most basic paradigms: ‘Out of Africa 1’.

The Biogeographic Implications of Early Hominin Phylogeny

TLDR
Results indicate that hominins dispersed at least four times between African regions, and that most hominin speciation events took place in eastern Africa.

Australopithecus sediba: A New Species of Homo-Like Australopith from South Africa

TLDR
Combined craniodental and postcranial evidence demonstrates that this new species of Australopithecus shares more derived features with early Homo than any other australopith species and thus might help reveal the ancestor of that genus.

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

TLDR
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.

Origins of Hominin Biocultural Diversity

TLDR
A large body of evidence to date, including palaeontological, geological, environmental, archaeological, ecological and biogeographic data allow the reconstruction of the major phases of early hominin evolution, including the onset of biocultural evolution of humans in Africa.

Hominin diversity in the Middle Pliocene of eastern Africa: the maxilla of KNM-WT 40000

TLDR
The results of statistical analyses show that the attribution of KNM-WT 40000 to a separate species and the notion that hominin taxonomic diversity in Africa extends back well into the Middle Pliocene are supported.

Australopithecus garhi: a new species of early hominid from Ethiopia.

TLDR
Discovery of 2.5 Ma hominid cranial and dental remains from the Hata beds of Ethiopia's Middle Awash allows recognition of a new species of Australopithecus, descended from Australipithecus afarensis and is a candidate ancestor for early Homo.

New four-million-year-old hominid species from Kanapoi and Allia Bay, Kenya

TLDR
The mosaic of primitive and derived features shows this species to be a possible ancestor to Australopithecus afarensis and suggests that Ardipithecus ramidus is a sister species to this and all later hominids.

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.

TLDR
The Pliocene hominid species Australopithecus afarensis is represented by cranial, dental, and mandibular remains from Hadar, Ethiopia, and Laetoli, Tanzania and appears to retain a primitive, rather than derived, morphology.
