Sessão The methodologies applied in bioarchaeology: apresentação de João Sardoeira


“Fracturas - O que analisar?”

João Bernardo Sardoeira

Departamento de Ciências da Vida, Faculdade de Ciências e Tecnologia da Universidade de Coimbra, Portugal

A fractura é a manifestação mais comum da patologia traumática, podendo ser caracterizada como uma descontinuidade, parcial ou completa, da superfície óssea e ter como origem um evento acidental, violento, uma prática clínica ou ser secundária a outra patologia. Após a sua ocorrência o organismo inicia imediatamente um processo de cicatrização, que poderá variar conforme o indivíduo e o osso afectado, e cujo objectivo será recuperar a estrutura original do osso.
À semelhança do estudo de outras paleopatologias, o trauma requer por parte dos investigadores especial atenção devido às diferentes manifestações que o mesmo pode registar. O momento de ocorrência da lesão, se durante o período de vida do indivíduo ou se posterior ao momento da morte, a existência de complicações no momento de recuperação da fractura e o estado de fragmentação do material analisado, são tudo barreiras que se podem levantar aquando do estudo desta condição patológica. Para as ultrapassar, é essencial ao investigador um conhecimento abrangente da variabilidade que diferentes tipos de fracturas podem apresentar, assim como, as principais características que as definem.
Esta comunicação tem então como objectivo a apresentação de diferentes manifestações de fractura, através da exibição de casos identificados numa amostra de 129 indivíduos do século XIX da cidade do Porto, e ainda, a discussão das mesmas e dos possíveis mecanismos que as causaram.

“A biocultural approach to the study of musculoskeletal stress markers (MSM) in a skeletal sample from Constância, Portugal (14-19th centuries): limitations and achievements”

Sandra Assis
Centro de Investigação em Antropologia e Saúde,
Department of Life Sciences, University of Coimbra, Portugal

Paleopathological studies have revealed a connection between some types of bone lesions and the stress produced during the performance of certain activities. The biocultural approach here presented aims to combine the skeletal evidence, through the study of musculoskeletal stress markers (MSM) in a sample from both sexes (N=64) exhumed from the Constância necropolis (14th-19th centuries), with historical, ethnographic and economic data, indicating that fishing and ship building were dominant occupations among the inhabitants. Thirty-six body MSM sites were scored using the method of Mariotti et al. (2004). In the upper limb, the MSM mean scores were higher in females than males. The opposite was noted for the musculoskeletal insertions of the lower limb. In males, alterations at the costoclavicular ligament predominate, while in females those of the supinator muscle were most frequently observed. The lower limb MSMs most affected were the quadriceps femoris muscle in males, and the gluteal muscles in females. The sexual dimorphism was higher in females with respect to upper anatomical sites. Age at death proved to be a contributing factor to increased MSM values. From the MSM results, as well as from some degenerative joint disease data, it is possible to conclude that the ancient inhabitants of Constância would have been subjected to acute episodes of biomechanical stress. Some reflections, considering the difficulties found in the methodology and during the data collection will also be made.

Entre os dias 11 e 12 ocorreram as sessões "The methodologies applied in bioarchaeology" e " From primates arqueology to human evolution" coodenardas por sócios do Grupo de Estudos em Evolução Humana.

The methodologies applied in bioarchaeology
Vanessa Campanacho e Luís Miguel Marado

Bioarchaeology intends, with its analysis, to extract information from osteological remains and contribute to the reconstruction of individuals’ and communities’ past lives. The human skeleton holds a great deal of information pertaining to the interaction between biology and behaviour. This scientific discipline acts on two instances: directly on the archaeological site and on the laboratory. The appropriate methods are employed on both these locations, so as to establish the degree of osseous preservation, how the osseous tissue will be maintained, the individuals’ biological profile, funerary rites, pathological condition, ritual and occupational behaviours, issues of biological relatedness and paleodemography. The achieved results much contribute to the characterization of adaptive change, biological impact originating on the movement of populations (invasions, colonization, etc.), social status, conflicts and resource limitations. As time goes by, new methodologies have emerged: 1) showing modification to existing methods, as happened with the changes to Todd’s (1920) age-at-death estimate pertaining to the osseous degeneration of the pubic symphysis; 2) using state-of-the-art technology, like new methods that apply three-dimensional scanning; 3) as well as methodological approaches that lack divulging, and so are scarcely applied today. In this session it’s intended that new methodologies are exposed and existing ones are tested, further discussing their relevance, reliability, limitations, advantages and disadvantages when applied to the evaluation of skeletal remains from archaeological context. The search for the past of human populations must have diversified and objective sources, guaranteeing the broadest and most accurate interpretation of material (as well as written) documentation as possible.


FROM PRIMATE ARCHAEOLOGY TO HUMAN EVOLUTION

Susana Carvalho (na fotografia)

The history of human origins and evolution can be portrayed as a shifting puzzle, remarkably fascinating, however far from being complete. In the challenging goal of reconstruct our evolutionary past, the recent fossil discoveries, as well as, the introduction of new tools of research have played a major role. In the last decade, an increasing development of interdisciplinary studies lead by Portuguese researchers has occurred. The search for answers about some of the most complex questions concerning our evolution and material culture has been the main focus. Thus, Paleoanthropology, Genetics, Primatology, Archaeology, are all linked and under current exploration by young researchers, with new innovative approaches. This session aims to promote the need of bridging different disciplines to further understand Human Evolution, with a particular focus on the recent “Primate Archaeology” manifesto. Studies focusing the material culture on non-human primates will serve as a basis to discuss the implications of using non-human primates as models to understand the earliest technologies in Africa.
