Associate Professor Victoria Gibbon
Associate Professor Victoria Gibbon joined the Division of Clinical Anatomy and Biological Anthropology in 2016. She is a NRF rated scientist with 38 journal publications and 44 presentations at conferences. In addition to her research and teaching portfolios she is curator of the UCT Human Skeletal Repository. A role that has led her to initiate restitution processes at UCT to return unethically obtained human remains and led to establishment of updated procedures of access and stewardship of human remains at UCT. Here research has shown an interest in ethical practice in relation to ancient DNA and sampling.
As a species, humans have less than 6% genetic variation between them, compared to chimpanzees with 33% and gorillas with 66%, we are genetically uniform. Despite this uniformity, human variation is poorly understood. Intraspecies variation is important as it demonstrates micro-evolutionary processes (mutations, migration and selection) that become advantageous in a given environment. A better understanding of human variability, past and present, is important to understand our adaptive potential as a species in an ever-changing environment. She uses a three-prong approach in her biological anthropological research theoretical, technological and biological. Theoretically she has an integrative perspective and use a biocultural approach. With this approach she tried to explain and explore the genetic and environmental factors responsible for biological variation that allows people to be understood in their own cultural and environmental context. She uses this biological understanding to scrutinise, and challenge biased historical accounts to provide an objective view into past people’s lives from a cultural relativist perspective. To investigate variation, along with traditional methods of analyses, she uses technologically innovative ways of understanding and reconstructing the biology of past peoples.
Her research and teaching interests are primarily in biological anthropology, human variation, forensic anthropology and bioarchaeology. Her diverse background and training in anatomical, genetic, medical and anthropological sciences allows her to conduct research on a variety of topics, which provides a multitude of research opportunities for students.

One of my primary areas of research focuses on changes in body shape and size through time and space. My focus is principally bioarchaeological which is the application of human skeletal analyses to remains found in an archaeological context, to better understand the mechanisms that drive human variation and how it is displayed biologically in the skeleton. I am particularly interested in how the skeleton has changed over a known time period in response to environmental adaptation and genetic admixture. This research provides a compelling glimpse into how people lived and allows us to explore their biological quality of life. I have found that there is more morphological variation in the skeleton than previously thought, but I am also able to question historical accounts of past people and cast them in their own light. Through these areas of research, I maintain and established an active interdisciplinary research program with both national and international collaborations.

I also have a project on living people aimed at better understanding growth and development in the South African population. Infant growth in South Africa is tracked using the universal growth standard, my PhD student, Liesl Arendse, is assessing the accuracy of this standard for evaluating and tracking healthy growth of South Africans.
Forensic Anthropology: Decomposition, taphonomy and identification
Another primary area of research for me is in the field of forensic anthropology, where my research is primarily focused on forensic identification and taphonomy. The burden of unidentified persons in South Africa is significant. The identification of deceased persons is of great importance for criminal, social, humanitarian, ethical and civil reasons. Identification of the deceased becomes challenging in those involving decomposed, skeletonised or burnt remains. In cases such as these forensic anthropologists and geneticists are often requested to assist reconstruct the biological profile of the individual. When attempting to match a demographic profile to a list of missing persons, an accurate estimate of the persons demographic details (sex, age, ancestry and stature) and an accurate time-since death can reduce the number of suspected candidates and significantly improving the likelihood of victim identification. With identification I have several projects in Forensic genetics done in collaboration with Dr. Laura Heathfield, in addition to morphometric based studies. I have an active forensic taphonomy research group, where my team in collaboration with Dr. Devin Finaughty of Kent University are pushing the global standards for this kind of research.

Mseleni Joint Disease
Due to my expertise in biological anthropology, genetics and using a holistic perspective for human variability, I was consulted by the late Prof. J Harington (University of the Witwatersrand, SA) to examine the aetiology/ies of Mseleni Joint Disease. It is geographically confined to a remote area in the Maputaland region in northern Kwazulu Natal, South Africa. This disease affects most joints but primarily those of the hip. Mseleni joint disease is characterised by two distinct abnormalities, protrusio acetabuli that mainly affects females and increases in frequency with age, and hip dysplasia that is more frequent with age. Despite various avenues of research since its discovery in 1970 its aetiology remains unknown. To better understand the genetics of this disease we initially wrote a review paper summarising the completed work on the condition in attempt to produce genetic targets for treatment and prevention (Joint Bone Spine 77:399-404, 2010). Its socio-economic impacts, the demographics, diet, geology and the genetic background of affected people are reviewed and examination of epigenetic mechanisms and stable isotope analysis of teeth are suggested as a means of providing information on the aetiology of the disease, which I am currently investigating click here.
