Available in PDF, EPUB and Kindle. Book excerpt: Abstract Cranial Morphology, Variation, and Integration in Homo sapiens by Whitney Brooke Reiner, Doctor of Philosophy in Integrative Biology University of California, Berkeley Professor Leslea Hlusko, Chair Herein I present three separate manuscripts pertaining to cranial morphology, variation, and integration in humans. The first manuscript introduces a newly recovered partial calvaria, OH 83, from the upper Ndutu Beds of Olduvai Gorge, Tanzania. I present the geological context of its discovery, a comparative analysis of its morphology, and place OH 83 within the context of our current understanding of the origins and evolution of Homo sapiens. The morphology of OH 83 was analyzed using quantitative and qualitative data from penecontemporaneous fossils and the W.W. Howells modern human craniometric dataset. OH 83 is geologically dated to ca. 60-32 ka. Its morphology is indicative of an early modern human, falling at the low end of the range of variation for post-orbital cranial breadth, the high end of the range for bifrontal breadth, and near average in frontal length. There have been numerous attempts to use cranial anatomy to define the species Homo sapiens and identify it in the fossil record. These efforts have not met wide agreement by the scientific community due, in part, to the mosaic patterns of cranial variation represented by the fossils. The variable, mosaic pattern of trait expression in the crania of Middle and Late Pleistocene fossils implies that morphological modernity did not occur at once. However, OH 83 demonstrates that by ca. 60-32 ka modern humans in Africa included individuals that are at the fairly small and gracile range of modern human variation. In the second manuscript I provide craniometric data from Early Period (ca. 5000 B.P.) hunter-gatherers from the Sacramento Valley and the San Francisco Bay Area that represent some of the earliest indigenous Californians. I compare these data to the published worldwide human craniometric data set to provide perspectives on the range of human variation and the inter-relatedness of that variation. I collected 76 cranial measurements and five indices from 59 adult crania collected using a three-dimensional (3D) digitizer (MicroScribe G2, Immersion Corporation), following published protocols associated with the comparative data set. I conducted two sets of analyses exploring the range of variation, and calculating correlations. My analyses reveal that the Early Period Native Californians extends the known range of variation for 20 measurements. For six of the measurements, the smaller end of the range is extended, while the higher end of the range is extended for 14 measurements. For Native Americans, the Early Period Native Californians extend the range for 53 measurements, four of which are extended at both ends of the range. Correlation matrices for these data suggest the face is an integrated region of the cranium across modern humans, but specific patterns of correlation within and between regions of the cranium varied across populations. The early Native Californian crania exhibited the strongest overall correlations, differing significantly from the other samples (Mantel test, p
Download or read book Epigenetic Variants of the Human Skull written by Gertrud Hauser and published by E. Schweizerbartsche Verlagsbuchhandlung. This book was released on 1989 with total page 328 pages. Available in PDF, EPUB and Kindle. Book excerpt: With this atlas on ``Epigenetic Variants of the Human Skull'' Hauser and De Stefano produced a much required reference work on minor cranial variants. These traits were named epigenetic since they may be seen as products of genetically determined growth processes of other tissues (e.g. nerves, vessels and muscles) affecting bone information. Consequently they may undergo modification during ontogeny in the presence of modifying genes or relevant environmental conditions and generally show variable degrees of expression. Many of these variants had already been described mainly as mere skeletal anomalies. Renewed interest resulted when crosses between inbred strains of mice established the potential value of minor skeletal variants in genetic studies. But in the light of the new experiences one may ask if the characters selected were the most useful for their purpose? Are they easy to identify, and are their definitions rigorous and unambigous ? What is known about their embryology and development, their genetic control? Was their categorisation adequate? Are they of any general medical, forensic or surgical relevance? What is the extent of intrapopulation variation in incidence ? How do they vary between populations ? This atlas endeavores to answer such questions and to serve as a reference text. The entry of each of the 84 characters summarises its nomenclature, gross anatomy, function, embryology and growth, genetics, medical relevance, sex differences, symmetry (if the character is bilateral), laterality or side preference, age variation, association with other traits, and methods of scoring (the traditional as well as that now proposed). For some traits new results are given applying the proposed methods to male adult skulls of recorded age and origin as well as the frequencies of the variants investigated by traditional methods in a selection of the populations of the world from the literature. The high quality photographs and the overlays (in colour) on the five main views of the skull illustrate each character clearly, better than any verbal definition. The collaboration of 13 international scientists specialised in different fields emphasizes the high quality of this book, and its usefulness for many disciplines as Human Biology and related sciences, Human Genetics, Forensic Medicine, Radiology, Surgery etc. A most extensive bibliography and a synoptical index conclude this reference work which confronts specialists of Human Biology, Anthropology, Medicine, Biology and Genetics with a fascinating problem but is also most useful and comprehensible for students.
Download or read book The Evolution of the Human Head written by Daniel Lieberman and published by Harvard University Press. This book was released on 2011-01-03 with total page 769 pages. Available in PDF, EPUB and Kindle. Book excerpt: Exhaustively researched and years in the making, this innovative book documents how the many components of the head function, how they evolved since we diverged from the apes, and how they interact in diverse ways both functionally and developmentally, causing them to be highly integrated. This integration not only permits the head's many units to accommodate each other as they grow and work, but also facilitates evolutionary change. Lieberman shows how, when, and why the major transformations evident in the evolution of the human head occurred. The special way the head is integrated, Lieberman argues, made it possible for a few developmental shifts to have had widespread effects on craniofacial growth, yet still permit the head to function exquisitely. --

Download or read book The Mismeasure of Man Revised and Expanded written by Stephen Jay Gould and published by W. W. Norton & Company. This book was released on 2006-06-17 with total page 458 pages. Available in PDF, EPUB and Kindle. Book excerpt: The definitive refutation to the argument of The Bell Curve. When published in 1981, The Mismeasure of Man was immediately hailed as a masterwork, the ringing answer to those who would classify people, rank them according to their supposed genetic gifts and limits. And yet the idea of innate limits—of biology as destiny—dies hard, as witness the attention devoted to The Bell Curve, whose arguments are here so effectively anticipated and thoroughly undermined by Stephen Jay Gould. In this edition Dr. Gould has written a substantial new introduction telling how and why he wrote the book and tracing the subsequent history of the controversy on innateness right through The Bell Curve. Further, he has added five essays on questions of The Bell Curve in particular and on race, racism, and biological determinism in general. These additions strengthen the book's claim to be, as Leo J. Kamin of Princeton University has said, "a major contribution toward deflating pseudo-biological 'explanations' of our present social woes."

Download or read book The Sutures of the Skull written by Mehmet Turgut and published by Springer Nature. This book was released on 2021-06-02 with total page 440 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book provides an in-depth review of the sutures of the skull. The premature closure of the sutures of the skull (craniosynostosis) due to genetic or metabolic etiologies results in typical progressive skull deformity, due to both the inhibition of growth caused by the affected cranial suture and associated compensatory expansion of the skull along the open ones. Today, it is well known that early diagnosis of craniosynostosis is crucial for the best surgical outcomes and for the normal development of the brain and cosmetic appearance of the skull. As such, in addition to the anatomy, biology, genetics and embryology of the sutures of the skull, the book also covers the diagnosis and treatment of different forms of craniosynostosis such as metopism, and animal models for cranial suture research. This comprehensive work is a valuable resource for neuroscientists at all levels, from graduate students to researchers, as well as neurosurgeons, neuroanatomists, pediatricians, and neurologists seeking both basic and more advanced information on the unique structure of the sutures of the human skull.
