The many mysteries of Homo naledi
More than 1500 fossils from the Rising Star cave system in South Africa have been assigned to a new human species, Homo naledi, which displays a unique combination of primitive and derived traits throughout the skeleton.

Mapping Interactions of H. neanderthalensis and Homo sapiens from the Fossil and Genetic Records
Evidence suggests that the Neanderthal and Homo sapiens lineages began diverging about 600,000 years ago, evolving largely separately in Eurasia and Africa after that time. Around 60,000 years ago H. sapiens began a significant emergence from Africa that would lead to a near-global distribution by…

Comparative 3D Shape Analysis of the Iwo Eleru Mandible, Nigeria
The Iwo Eleru skeleton is the only Pleistocene human fossil currently known from Western Africa. Previously, we showed morphological affinities of the Iwo Eleru cranial remains with Pleistocene archaic African specimens, consistent with former interpretations of this specimen. Those results…

Multiplexed SNP typing of ancient DNA clarifies the origin of Andaman mtDNA haplogroups amongst South Asian tribal populations.
The issue of errors in genetic data sets is of growing concern, particularly in population genetics where whole genome mtDNA sequence data is coming under increased scrutiny. Multiplexed PCR reactions, combined with SNP typing, are currently under-exploited in this context, but have the potential…

The Later Stone Age calvaria from Iwo Eleru, Nigeria: morphology and chronology.
BACKGROUND: In recent years the Later Stone Age has been redated to a much deeper time depth than previously thought. At the same time, human remains from this time period are scarce in Africa, and even rarer in West Africa. The Iwo Eleru burial is one of the few human skeletal remains associated…

Global patterns of the cranial form of modern human populations described by analysis of a 3D surface homologous model
Abstract This study assessed the regional diversity of the human cranial form by using geometric homologous models based on scanned data from 148 ethnic groups worldwide. This method adopted a template-fitting technique for a nonrigid transformation via the iterative closest point algorithm to…

Bioclimatic and masticatory influences on human cranial diversity verified by analysis of 3D morphometric homologous models
Abstract This study analyzes the effects of bioclimate and masticatory factors on the regional variability of human cranial forms across 150 ethnic groups worldwide. Morphometric variables were generated using principal component analysis applied to 3D homologous models. Relationships between…

A Refined Chronology for the Middle–Upper Paleolithic Transition at Kozarnika Cave (Bulgaria) 40–50,000 Years Ago
The site of Kozarnika in Bulgaria is a key, deep (~6m) archaeological sequence spanning the Lower, Middle and Upper Paleolithic of Europe. In its latter phases, it documents the transition from a Neanderthal-dominated Europe to one in which only modern humans are present. The process of this…

Nubian Levallois technology associated with southernmost Neanderthals
Abstract Neanderthals occurred widely across north Eurasian landscapes, but between ~ 70 and 50 thousand years ago (ka) they expanded southwards into the Levant, which had previously been inhabited by Homo sapiens. Palaeoanthropological research in the first half of the twentieth century…

Geochemical provenancing and direct dating of the Harbin archaic human cranium
As one of the most complete archaic human fossils, the Harbin cranium provides critical evidence for studying the diversification of the Homo genus and the origin of Homo sapiens. However, the unsystematic recovery of this cranium and a long and confused history since the discovery impede its…

Massive cranium from Harbin in northeastern China establishes a new Middle Pleistocene human lineage
It has recently become clear that several human lineages coexisted with Homo sapiens during the late Middle and Late Pleistocene. Here, we report an archaic human fossil that throws new light on debates concerning the diversification of the Homo genus and the origin of H. sapiens. The fossil was…

Hominin Footprints from Early Pleistocene Deposits at Happisburgh, UK
Investigations at Happisburgh, UK, have revealed the oldest known hominin footprint surface outside Africa at between ca. 1 million and 0.78 million years ago. The site has long been recognised for the preservation of sediments containing Early Pleistocene fauna and flora, but since 2005 has also…
