The D4500 (Skull 5), dated 1.8 Mya., is the most complete fossil within the set of five skulls found in Dmanisi, Georgia, as well as any other fossils associated to contexts of occupation of the early Pleistocene. Its discovery has brought forward the debate of the plurality of species, not just at the beginning of the Homo genus, but for much of its evolution.  The Skull 5 fossil presents a mixure of primitive and derivates characters associated to the Homo erectus and Homo habilis sensu lato…

A Complete Skull from Dmanisi, Georgia, and the Evolutionary Biology of Early Homo
TLDR
The Dmanisi sample, which now comprises five crania, provides direct evidence for wide morphological variation within and among early Homo paleodemes, implying the existence of a single evolving lineage of early Homo, with phylogeographic continuity across continents.
Implications of new early Homo fossils from Ileret, east of Lake Turkana, Kenya
TLDR
Two new cranial fossils from the Koobi Fora Formation, east of Lake Turkana in Kenya, are described that have bearing on the relationship between species of early Homo and confirm the distinctiveness of H.’shabilis and H.erectus, independently of overall cranial size, and suggest that these two early taxa were living broadly sympatrically in the same lake basin for almost half a million years.
A New Skull of Early Homo from Dmanisi, Georgia
TLDR
The Dmanisi specimens are the most primitive and small-brained fossils to be grouped with this species or any taxon linked unequivocally with genusHomo and also the ones most similar to the presumedhabilis-like stem.

TLDR
The following null hypothesis is tested: polytypism was established relatively early and the species H. erectus can accommodate all spatio-temporal variation from ca.
Homo in the middle pleistocene: Hypodigms, variation, and species recognition
TLDR
In this essay, the evidence available from Middle Pleistocene localities in Africa and Europe is emphasized, exploring variation among individuals, composition of hypodigms, species‐level taxonomy, and evolutionary relationships of the hominin populations.
Fossil Skulls from Dmanisi: A Paleodeme Representing Earliest Homo in Eurasia
The Plio-Pleistocene site of Dmanisi has yielded much evidence bearing on the morphology and behavior of the earliest hominins from western Eurasia. Human remains, animal bones and stone artifacts…

TLDR
The fossil evidence from ∼2.5 to 1.5 Ma forms the baseline for understanding the origin of the genus and early H. erectus is less “modern” and its regional variation in size more substantial than previously allowed.
Earliest Pleistocene hominid cranial remains from Dmanisi, Republic of Georgia: taxonomy, geological setting, and age.
TLDR
Paleontological, archaeological, geochronological, and paleomagnetic data from Dmanisi all indicate an earliest Pleistocene age of about 1.7 million years ago, supporting correlation of the new specimens with the Koobi Fora fossils.
A fourth hominin skull from Dmanisi, Georgia.
TLDR
A fourth skull that is nearly complete, lacking all but one of its teeth at the time of death is described, arguing that the relatively small-brained and lightly built Dmanisi hominins may be ancestral to African and Far Eastern branches of H. erectus.
Homoplasy and early Homo: an analysis of the evolutionary relationships of H. habilis sensu stricto and H. rudolfensis
TLDR
A cladistic analysis of 48 of the most commonlyused cranial characters from recent studies of Pliocene hominid phylogeny and which distinguish two taxa within H. habilis sensu lato suggests that these fossils have different evolutionary affinities.
