The topic of archaeological illness research is based on the use of the human skeletal record to reveal the presence of diseases in the past. Bioarchaeology, paleopathology, and biomolecular analyses are among the techniques that can be applied by researchers to discover diseases like infections, nutritional deficiencies, and degenerative conditions in ancient populations. DNA sequencing, isotope analysis, and radiography are some of the tools that can be used by researchers to detect diseases such as tuberculosis and the bubonic plague from ancient remains. Such techniques allow the researchers to gain insights into the evolution of diseases, past medicine trends, and the surrounding environment of the people.
Paleopathology explains how ancient diseases are found in human remains
The archaeology of illness, also known as paleopathology, involves the examination of diseases in ancient human and animal remains. The examination of abnormalities on bones, wear on teeth, and burial conditions helps to draw conclusions about diseases in the population. In an article titled ‘The Bioarchaeology of Health Crisis: Infectious Disease in the Past,’ Clark Spencer Larsen, a prominent bioarchaeologist, notes that “human skeletons are rich records of life experience, including diseases, nutrition, and biological stress.”Through paleopathology, we gain insights into the lives of previous generations through the analysis of diseases, which are preserved in bones and tissues.
Scientific techniques used to identify ancient diseases
The modern science has revolutionized ways in which diseases are detected in fossils of the past. One such advanced technique is the ancient DNA or aDNA studies. Scientists have the ability to retrieve DNA from bones or tooth samples and study the pathogen. According to Bos et al. (2011), who studied the genomic structure of the bacterium causing the Black Death, “We show that Yersinia pestis was the causative agent of the Black Death.” Another important method is the isotope analysis. Studying the chemical composition of the bone, scientists are able to deduce the migratory history and dietary habits of individuals, which are strongly associated with good health. Another technology is the radiographic imaging, which includes CT scans. These help in studying mummified bodies without damaging them. For instance, scientists analyzing the Egyptian mummies found evidence of hardening of arteries, a sign of atherosclerosis.
Diseases discovered in ancient populations
Several illnesses can be documented from the archaeology of the past. For example, tuberculosis infection has been found to exist in the remains of individuals that date back many years. According to study ‘Historic and Prehistoric Epidemics: An Overview of SourcesAvailable for the Study of Ancient Pathogens‘, some of the characteristics of tuberculosis include spine damage, which is referred to as Pott’s disease.There are also incidences of leprosy infection, which is evident from peculiar features of the bones found on the face and limbs of the bodies. Malnutrition cases are also common, which involve such conditions as rickets and scurvy.In addition, scientists have managed to find out that plague DNA exists in large burial places.
Why studying ancient disease matters today
Besides offering insights into past events, the investigation of ancient diseases is beneficial to contemporary medical practice. Studying the development of pathogens can help in forecasting the occurrence of future pandemics.Moreover, research on historical trends in human well-being allows medical professionals to assess the impact of various environmental and socioeconomic factors on the development of illness. Such an approach is especially useful in analyzing the etiology of current diseases associated with lifestyle.The study of the pathology of ancient populations offers insight into the human experience captured in physical form. With the help of cutting-edge technology, researchers are able to uncover the mysteries of past disease.
