With opulent graves but no written records, the empire and its people have remained largely in the shadows of history until recently. But a landmark April 2022 study involving ancient DNA taken from the graves of the Avar elite shed light on the empire’s far-flung origins. A tiny sample is drilled from a bone at the ancient DNA laboratory at the Max Planck Institute for Evolutionary Anthropology in Leipzig, Germany. In the case of men, researchers found two partners in 10 cases, three partners in four cases and four partners in one case. “Polygamy (having multiple marriage partners), serial monogamous marriages and extramarital relations are all possible explanations,” she said.

The rare find could help scientists further understand how changes in the human diet have led to the prevalence of cavities today. Uncovered during two excavations from 1993 and 1996, the teeth were among several human teeth and other remains found within a limestone cave in County Limerick in Ireland. One tooth had a surprising abundance of Streptococcus mutans (S. mutans), an oral bacteria that causes cavities. Researchers also believe the bacteria is not as commonly found within ancient teeth because the human diet included less refined sugar and fewer processed foods than are consumed today, Cassidy said. … ancient teeth can help us understand how the human oral microbiota (range of microorganisms) has evolved over time and the impact of these changes on human health in the past and today,” Humphrey said in an email.
