Recent years have seen the discovery of numerous new hominid species, and the hominid evolutionary tree is now commonly drawn as a complex bush. In his Perspective, White raises a cautionary note, arguing that some fossils may be so distorted that assignment to a new species is premature. Furthermore, natural variation among species must be taken into consideration. The author concludes that it is too early to say whether many more hominid lineages are waiting to be found and recognized in… 

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.

The First Hominins and the Origins of Bipedalism

Molecular and paleontological evidence now point to the last common ancestor between chimpanzees and modern humans living between five and seven million years ago, which is close to the root of the hominin lineage.

On the Number of Ancestral Human Species

The fossil record is shown to likely dramatically under sample species diversity for the hominin clade while at the same time substantially underestimating species longevity, suggesting the human clade may be characterised by a large number of rapidly evolving and relatively short-lived species.

Late Australopiths and the Emergence of Homo

A review of the latest discoveries and research reveals that potential convergent evolution in adaptively significant features in late australopiths and basal members of the Homo clade makes it currently impossible to identify the direct ancestor of Homo erectus.

The Macroevolution of our Ancient Lineage: What We Know (or Think We Know) about Early Hominin Diversity

It is argued that for many species the authors' limited understanding of within species variation hampers the ability to make taxonomic decisions with any level of statistical certainty.

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.

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.

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.

Palaeoanthropology: Hominid revelations from Chad

The story of human origins in Africa takes a twist with the description of a 6–7-million-year-old cranium from Chad. The discovery hints at the likely diversity of early hominids.

Classification and human evolution

A comparison of the Ecology and Behavior of Monkeys and Apes and the Taxonomic Evaluation of Fossil Hominids shows that monkeys and apes have more in common with each other than with other primates.

New Middle Pleistocene hominid crania from Yunxian in China

The Yunxian crania, although crushed and distorted to varying degrees, are unusual in having major elements of the basicranium, palate, face and cranial vault preserved together and throw new light on Middle Pleistocene hominid diversity and the relationships among regionally disparate Middle Pleistsian hominids.

Sphenoid shortening and the evolution of modern human cranial shape

Sphenoid reduction, through its effects on facial projection and cranial shape, may account for the apparently rapid evolution of modern human cranial form, and suggests that Neanderthals and other archaic Homo should be excluded from H. sapiens.

Anterior sphenoid in modern humans

It turns out that the anterior sphenoid in modern humans is no shorter than in archaic Homo, and ASL was incorrectly estimated in those archaic fossil crania in which these landmarks are unambiguously preserved.
