Brain development is similar in Neanderthals and modern humans

4.06 – Differences in Brain Organization Between Neanderthals and Modern Humans

Homo sapiens and Neanderthals share high cerebral cortex integration into adulthood

It is shown that strong covariation between different areas of the brain in Homo sapiens and Homo neanderthalensis evolved under higher evolutionary rates than in any other primate, suggesting that natural selection favoured a greatly integrated brain in both species.

The evolution of modern human brain shape

This work analyzes endocranial casts of Homo sapiens fossils from different time periods to show that, 300,000 years ago, brain size in early H. sapiens already fell within the range of present-day humans.

Neonatal postcrania from Mezmaiskaya, Russia, and Le Moustier, France, and the development of Neandertal body form

Neandertal neonates studied are able to establish that, as for the skull, many differences in body form are present by the time of birth, and it is found that neonatal Neandertals already appear to possess the wide body, long pubis, and robust long bones of adult Ne andertals.

Evolution of the base of the brain in highly encephalized human species.

Three-dimensional geometric morphometric analyses of endobasicranial shape reveal previously undocumented details of evolutionary changes in Homo sapiens, including larger olfactory bulbs, relatively wider orbitofrontal cortex, relatively increased and forward projecting temporal lobe poles appear unique to modern humans.

Endocranial ontogeny and evolution in early Homo sapiens: The evidence from Herto, Ethiopia

The results suggest that the peculiar shape of early Homo sapiens adult braincases was likely due to dietary and lifestyle differences rather than different brain anatomy.

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.

Dental evidence for ontogenetic differences between modern humans and Neanderthals

It is found that most Neanderthal tooth crowns grew more rapidly than modern human teeth, resulting in significantly faster dental maturation, consistent with recent cranial and molecular evidence for subtle developmental differences between Neanderthals and H. sapiens.

Brain ontogeny and life history in Pleistocene hominins

The current palaeoanthropological evidence shows that, regarding life history and brain ontogeny, the Pleistocene hominin taxa display different patterns and that one cannot simply contrast an ‘ape- model’ to a ‘human-model’.

Neanderthal brain size at birth provides insights into the evolution of human life history

Virtual reconstructions of a Neanderthal neonate from Mezmaiskaya Cave (Russia) and of two Neanderthal infant skeletons from Dederiyeh Cave (Syria) now provide new comparative insights: Neanderthal brain size at birth was similar to that in recent Homo sapiens and most likely subject to similar obstetric constraints.

Facial ontogeny in Neanderthals and modern humans

One hundred and fifty years after the discovery of Neanderthals, it is held that this morphologically and genetically distinct human species does not differ from modern Homo sapiens in its…

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.

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.

Encephalization and allometric trajectories in the genus Homo: Evidence from the Neandertal and modern lineages

The origin of the authors' species may have represented the opportunity to surpass the constraints imposed on encephalization by the ontogenetic pattern shared by nonmodern Homo representatives, and two different evolutionary trajectories are identified.

Neandertal birth canal shape and the evolution of human childbirth

The size of Tabun's reconstructed birth canal indicates that childbirth was about as difficult in Neandertals as in present-day humans, but the canal's shape indicates that Ne andertals had a more primitive birth mechanism.

A Draft Sequence of the Neandertal Genome

The genomic data suggest that Neandertals mixed with modern human ancestors some 120,000 years ago, leaving traces of Ne andertal DNA in contemporary humans, suggesting that gene flow from Neand Bertals into the ancestors of non-Africans occurred before the divergence of Eurasian groups from each other.
