Researchers have discovered a significant diversity of genetic material preserved in the Turin Shroud, which many revere as the cloth that wrapped the body of Jesus Christ after the crucifixion.
Discovery of Genetic Traces
The analysis showed the presence of DNA from dozens of plant and animal species, as well as genetic traces of at least 14 individuals of different origins, providing new insights into the biological history of this cloth. According to scientists, the amount of DNA extracted from the Turin Shroud was higher than expected even for a very frequently used blanket.
Types of Remains Found
Among the identified traces were organisms such as carrots and tomatoes, as well as fish, dogs, and cats that came into contact with the fabric over centuries. The Turin Shroud continues to spark debate: it has been revered for centuries as a presumed burial shroud, but its authenticity remains a subject of discussion among believers and skeptics.
History and Research Methods
The exact origin of the cloth is unknown; the earliest recorded fact of its appearance dates back to 1354 in Liri (France). To better understand the object's history, researchers used organic residues collected from the surface of the fabric in 1978. These samples were re-examined using modern genetic analysis methods, which allowed for the identification of a wide spectrum of species that contacted the shroud.
Human DNA Analysis
The analysis revealed DNA from at least 14 individuals from different parts of the world. Researchers claim that one of the genetic profiles almost certainly belongs to a scientist who collected samples in the 1970s, described as being of European and Jewish descent. A rare genetic trait associated with the Aramaic Druze people living in the Middle East was also found. Another surprising result was the discovery that nearly 40% of all human DNA found originated from India. The most likely explanation for this is that the flax used to make the fabric was imported from the Indus Valley.
Plants, Animals, and Marine Organisms
In addition to human DNA, the study revealed a great diversity of plant and animal genetic material. Among the cultivated plants identified were tomatoes, cucumbers, melons, potatoes, and pistachios. The authors of the study noted a strong presence of peanuts, belonging to the Fabaceae family. Traces of bananas, peppers, corn, and carrots were also found. Among the animals were dogs, cats, chickens, pigs, and cattle, as well as horses and rabbits. DNA from almonds and walnuts was also found in the analyzed samples.
Marine Contaminants and History Reconstruction
The investigation also revealed unusual marine contaminants, including Atlantic cod and anchovy. Furthermore, red coral from the Mediterranean, which was used in Roman times for making jewelry and other symbolic items, was identified. Although researchers cannot determine how, when, or where each species contacted the Turin Shroud, some findings help establish a timeline for some of these contaminants. For example, the detected carrots belong to European varieties that were first cultivated between the 15th and 16th centuries. Moreover, many identified species originate from Latin America, and the authors suggest this occurred only after historical voyages that led to the arrival of Europeans in America in 1492.
Significance of Genetic Analysis
Although the study does not answer questions about the age or authenticity of the relic, genetic analysis provides new information about its journey. Professor Naomi Procopio, one of the study's authors, stated in her statement: 'The Turin Shroud represents a rich archive of genetic information accumulated over centuries of human interaction and environmental impact.' She added that 'while DNA evidence cannot answer all questions about the age or authenticity of the cloth, it gives a new perspective on its biological history and demonstrates how forensic science advancements can reveal new information from historical artifacts.' The results were published in Scientific Reports.
