SALEKHARD, RUSSIA—Scientists continue to study the well-preserved remains of a six- or seven-year-old boy whose medieval birch bark coffin was recovered from the Zeleny Yar necropolis. So far, they have learned that the boy had worms from eating raw or undercooked fish, which may have been a staple food fed to infants and small children. Petr Slominsky of the Institute of Molecular Genetics in Moscow told The Siberian Times that his team plans to gather DNA samples from the modern Khanty, Nenets, and Komi peoples, who live near the site of the necropolis, to compare with a sample from the remains. The task is complicated by damage to the remains caused by repeated thawing and freezing and by resin in the birch bark used to wrap the body. "The DNA we get is not very clean, and there is not very much of it," said Slominsky. "But at the moment we are working to clear the DNA and get more samples and as soon as we succeed we will start the analysis."
