The term “encephalization” is commonly used to describe an enlargement in brain size, considered as either absolute endocranial volumes or relative values in relation to body size. It is widely recognized that a considerable endocranial expansion occurred throughout the evolution of the genus Homo. This article aims to evaluate whether this phenomenon was the outcome of distinct evolutionary lineages, reaching similar brain expansions but through different trajectories. Endocranial morphology…

Evidence for expansion of the precuneus in human evolution
Comparison of medial brain morphology between humans and chimpanzees and MRI-derived structural brain templates suggests that precuneus expansion is a neurological specialization of H. sapiens that evolved in the last 150,000 years that may be associated with recent human cognitive specializations.

In this comparative framework, paleoneurology deals with the analysis of the endocranial cavity in extinct species, in order to make inferences on brain evolution, and a main target of this field is to distinguish the endocanial variations due to brain changes, from those due to cranial constraints.
A Shared Pattern of Postnatal Endocranial Development in Extant Hominoids
It is demonstrated that from late infancy to adulthood ontogenetic trajectories are similar among all hominoid species, but differ in the amount of shape change, and that during early ontogeny gorillas undergo more pronounced shape changes than do chimpanzees, indicative of a dissociation of size and shape change.
Functional Craniology, Human Evolution, and Anatomical Constraints in the Neanderthal Braincase
Geometrical and structural constraints between the endocranial soft and hard tissues may have induced morphogenetic limits to the growth and developmental processes and it is tempting to wonder whether these limits may be also related to possible factors associated with the extinction of Neanderthals.
Increased morphological asymmetry, evolvability and plasticity in human brain evolution
This study uses geometric morphometric techniques to evaluate inter- and intraspecific differences in cerebral morphology in a sample of in vivo magnetic resonance imaging scans of chimpanzees and humans, with special emphasis on the study of asymmetric variation.
Encephalizations and Cerebral Developments in Genus Homo
Recent advances in the knowledge of intrinsic organization of cerebral cortex and in the patterns of genetic expression are able to better outline the trajectories as the metabolic and structural constraints of the qualitative and quantitative encephalic development.


The evolution and development of cranial form in Homo sapiens
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.
Body mass and encephalization in Pleistocene Homo
It is shown that two independent methods of body-mass estimation yield concordant results when applied to Pleistocene Homo specimens, and on the basis of an analysis of 163 individuals, body mass in Pleistsocene Homo averaged significantly (about 10%) larger than a representative sample of living humans.
Neanderthal cranial ontogeny and its implications for late hominid diversity
Computerized fossil reconstruction and geometric morphometrics are used to show that characteristic differences in cranial and mandibular shape between Neanderthals and modern humans arose very early during development, possibly prenatally, and were maintained throughout postnatal ontogeny.
Cranial discrete traits in the middle pleistocene humans from Sima de los Huesos (Sierra de Atapuerca, Spain). Does hypostosis represent any increase in "ontogenetic stress" along the Neanderthal lineage?
A general consistency between the gradual appearance and stabilization of the Neanderthal cranial features and the results of the present analysis are interpreted as an indication that hypostosis does mark the occurrence of "ontogenetic stress".

A multivariate analysis of Pleistocene hominids: testing hypothesis of European origins.
Multivariate analysis of intra- and inter-group variability in Middle and Upper Pleistocene human remains, based on facial traits, shows close affinities between Upper Palaeolithic and Mesolithic samples, which strongly support a monophyletic origin for modern humans.

Endocranial capacity of the bodo cranium determined from three-dimensional computed tomography.
The 600,000-year-old cranium from Bodo, Ethiopia, is the oldest and most complete early Middle Pleistocene hominid skull from Africa, and in spite of its large endocranial capacity, estimates of Bodo's encephalization quotient fall below those found in a large sample of Homo sapiens and Neandertals.
Matrix correlation tests support a single origin for modern humans
The first quantitative test of the fossil evidence for each of these models of human origins is given, finding that a single African and/or Levantine origin for modern humans is supported.
