Ancient Manuscripts Hold Secrets of the Past

Topic: Biology

Scientists developed a way to extract genetic information from ancient parchment manuscripts without damaging them. They tested this method on 91 historic documents and found new clues about trade, farming, and domesticated animals.

Scientists have discovered a way to recover cellular material from old manuscripts without harming the documents. These manuscripts are made of animal skin and were used for thousands of years in Europe, the Middle East, and parts of Africa.

The researchers, led by Tim Stinson from North Carolina State University, developed a technique that uses a dry cytology brush to gently collect cellular material from the parchment. This method is similar to how doctors take Pap smears. The team then used advanced technologies to analyze the genetic information preserved in the manuscripts.

The genetic information could reveal new details about trade, farming, and other aspects of life stretching back around 1,300 years. It may also help researchers understand how domesticated animals changed over time and what diseases affected livestock.

To test their method, the team collected samples from 91 manuscripts housed in the Rubenstein Library at Duke University. The documents came from locations ranging from England to Ethiopia and were produced between the late eighth and early 20th centuries.

Why It Matters

This discovery could help us learn more about our ancestors' lives and how they interacted with their environment. It may also provide new insights into the evolution of domesticated animals and diseases that affected them.
