Neanderthal pelvic morphology is not well understood, despite the recent find and analysis of the Kebara 2 pelvis. Many of the proposed hypotheses focus on the possible need for a larger birth canal. A previously unexplored aspect involves possible direct obstetric implications of bone robusticity and density. These characteristics ocan affect obstetrics in modern humans, especially the molding of the neonate's head during parturition: engineering studies have shown that denser neonate cranial… 
The Evolutionary Biology of the Human Pelvis
This book provides a synthetic overview of all evidence concerning the evolution of the morphology of the human pelvis, including comparative anatomy, clinical and experimental studies and quantitative evolutionary models, and is the first to bring all sources of evidence together to develop a coherent statement about the current state of the art in understanding pelvic evolution.
Neandertal growth: what are the costs?
Human-derived alleles in SOST and RUNX2 3′UTRs cause differential regulation in a bone cell-line model
This study reports a set of genes with derived 3’UTR changes in either the Homo sapiens or the Neanderthal/Denisovan lineages and experimentally evaluates the impact of 3'UTR variants in four genes: E2F6, GLI3, RUNX2 and SOST.
The Evolution of Human Sociability: Desires, Fears, Sex and Society
Professor Vannelli argues that human nature can be conceptualized as species-typical desires and fears, derived from sexual selection during human evolution, and that these can be treated as major motivators of human behaviour.
A New Examination of Childbirth-Related Pelvic Anatomy in Neandertal Females.

The Functional Significance of Neandertal Pubic Length [and Comments and Reply]
Although individual Neandertals fall outside the modern range of variation for pubic length, weight, and relative weight, the relationship among these variables is the same as in modern humans, providing support for the notion of morphological nd behavioral continuity between these human groups.
Kebara 2 Neanderthal pelvis: first look at a complete inlet.
The renewed excavations at the Kebara Cave revealed a Neanderthal skeleton dated at about 50-55,000 years B.P. The pelvis of this individual is the most intact Neanderthal pelvis yet discovered,
Bone mineral-osteon analysis of Yupik-Inupiaq skeletons.
Histological analysis of the femoral bone sections showed that Eskimos contain more osteons per unit area than U.S. whites, and differences in patterns of osteon remodeling between Eskimo and whites were inferred.
La Ferrassie 6 and the development of Neandertal pubic morphology.
Metric comparisons between the La Ferrassie 6 Neandertal infant, aged 3-5 years, and a sample of modern infants reveal that the acetabulosymphyseal length of La Ferrari 6, relative to femoral length and iliac breadth, falls at the limits of the range of variation of the modern infants.
Sexual dimorphism in the human bony pelvis, with a consideration of the Neandertal pelvis from Kebara Cave, Israel.

The hypothesis that variability and dimorphism are inversely related to pelvic variability fails to be supported and the factors that influence pelvic variability are discussed.
The structure of the human symphysis pubis with special consideration of parturition and its sequelae.

Review of the structure of the symphysis pubis shows changes from age, function, pregnancy hormones and stress of parturition, with older age degenerative arthritis is more frequent in parous females.
Bone density in Sadlermiut Eskimo.

There is little reason to believe that contact with whites caused any great changes in the general pattern of Sadlermiut life, and until their disappearance the Sadler miut must have maintained a traditional high protein, high fat, low carbohydrate diet derived principally from sea mammals.
Moulding of the Pelvis during Labour
The advent of roentgenography made it possible to obtain more exact information on the dimensions of the pelvis and their changes during pregnancy and labour.
Age at death of the Neanderthal child from Devil's Tower, Gibraltar and the implications for studies of general growth and development in Neanderthals.
If the cranial bones from Devil's Tower are associated with the dental material, as the authors believe, they indicate a remarkably precocious brain growth in this individual, which is consistent with what is known about general growth and development in Neanderthals.
