Our species Homo sapiens has never received a satisfactory morphological definition. Deriving partly from Linnaeus's exhortation simply to "know thyself," and partly from the insistence by advocates of the Evolutionary Synthesis in the mid-20th Century that species are constantly transforming ephemera that by definition cannot be pinned down by morphology, this unfortunate situation has led to huge uncertainty over which hominid fossils ought to be included in H. sapiens, and even over which of…

A new perspective on the origin of Homo sapiens
ABSTRACT In this paper, we critically review the current paradigm, which places the origin of Homo sapiens in Africa as the result of the evolution of a Middle Pleistocene species. In the African…
What constitutes Homo sapiens? Morphology versus received wisdom.

TLDR
It is argued that many specimens regarded as AMS, and all those deemed AS, are not H. sapiens, and the features these AMS do share with ES suggest the existence of a sapiens clade.
Human Paleontology and Prehistory: Contributions in Honor of Yoel Rak
TLDR
This interaction explains the extraordinarily fast tempo of evolution within the genus Homo by invoking perfectly routine evolutionary processes; and it eliminates any need for special pleading in the hominid case, at least in terms of mechanism.
Human Evolutionary History
What have the revelations about Neanderthal DNA revealed about Homo sapiens?
TLDR
The current information supports the existence of both replacement and interbreeding events, and indicates the need to revise the two main explanatory models, the Multiregional and the Out-of-Africa hypotheses, about the origin and evolution of H. sapiens and its co-relatives.
Muddying the muddle in the middle even more.
TLDR
In an Evolutionary Anthropology article Roksandic et al. (2022) propose a new middle Pleistocene hominin species H. bodoensis to replace a "poorly defined" Homo heidelbergenis, but provide no evidence as to how their new species meets their objectives.
Homo sapiens, Homo neanderthalensis and the Denisova specimen: New insights on their evolutionary histories using whole-genome comparisons
TLDR
The selective sweep that gave rise to Homo sapiens could, therefore, have initiated before the modern/archaic human divergence.
Resolving the “muddle in the middle”: The case for Homo bodoensis sp. nov.
TLDR
This work proposes the introduction of a new taxon, Homo bodoensis sp.
No known hominin species matches the expected dental morphology of the last common ancestor of Neanderthals and modern humans
TLDR
It is shown that no known fossil species is a suitable candidate for being the [N-MH]LCA and that all late Early and Middle Pleistocene taxa from Europe have Neanderthal dental affinities, pointing to the existence of a European clade originated around 1 Ma.
Hominin taxic diversity: Fact or fantasy?

  • 2016
TLDR
Not all new hominin taxa are created equally, but while taxic diversity may not be as prevalent as some have claimed, it is a feature of the hom inin clade from 4 Ma until c.40 ka years ago.

TLDR
Modern humans appear to have definitively exited Africa to populate the rest of the globe only after both their physical and cognitive peculiarities had been acquired within that continent.
Pleistocene Homo sapiens from Middle Awash, Ethiopia
TLDR
Fossilized hominid crania from Herto, Middle Awash, Ethiopia are described and provide crucial evidence on the location, timing and contextual circumstances of the emergence of Homo sapiens.
The evolution and development of cranial form in Homo sapiens
TLDR
Cranial variation among Pleistocene and recent human fossils is examined by using a model of cranial growth to identify unique derived features (autapomorphies) that reliably distinguish fossils attributed to “anatomically modern” H. sapiens from those attributed to various taxa of “archaic” Homo spp.
Homo erectus revisited: Aspects of affinity and diversity in a pleistocene hominin species
TLDR
Variation in cranial (? and body) size apparently persisted in African erectus with possible behavioural and socio-ecological correlates, and similar variability is lacking among the Asian fossils, implying major differences between African and Asian populations.
The Case for Sinking Homo erectus. 100 Years of Pithecanthropus is Enough!
TLDR
The regional ancestry of Homo sapiens populations makes monophyly impossible for the species if the earlier populations are in a different species, and reasons combine to require that the lineage be regarded as a single evolutionary species.
Evolution of the Genus Homo
TLDR
The evidence for “early Homo,” finding little morphological basis for extending the genus to any of the ∼2.5–1.6-myr-old fossil forms assigned to “ early Homo” or Homo habilis/rudolfensis, is looked at.
Postcranial evidence from early Homo from Dmanisi, Georgia.
TLDR
Newly excavated postcranial material from Dmanisi comprising a partial skeleton of an adolescent individual, associated with skull D2700/D2735, and the remains from three adult individuals shows that the postc Cranial anatomy of the D manisi hominins has a surprising mosaic of primitive and derived features.
Morphology, paleoanthropology, and neanderthals
TLDR
It is clear that the human fossil record reveals a consistent pattern of systematic diversity—a diversity totally unreflected in the conventional minimalist interpretation of that record, and the Neanderthals are conventionally classified simply as a subspecies of the authors' own species Homo sapiens—a classification that robs these extinct relatives of their evolutionary individuality.

  • 2006
TLDR
Lack of understanding of the history of human paleontology, and the biases that constrained its perspective on human evolution, continue to affect the ways in which most paleoanthropologists pigeonhole human fossils.
Significance of some previously unrecognized apomorphies in the nasal region of Homo neanderthalensis.

  • Geography, Biology

TLDR
The purpose of this contribution is to describe specializations of the Neanderthal internal nasal region that make them unique not only among hominids but possibly among terrestrial mammals in general as well.
