 Why in news

  • A study published in Proceedings of the National Academy of Sciences, analyzed ancient DNA from 28 elite graves and 24 previously sequenced genomes of the Longobards.

  • The researchers combined paleogenomics with archaeological and isotopic data to piece together social interactions, burial customs, and dietary habits among the Longobards.

  • They reported that the community was organised around a few related elite individuals drawn from multiple families. 

  • These families had also intermarried over time to ensure political power remained among their relatives.

  • This tradition gave way during the empire’s twilight when the families welcomed local community leaders as well in a bid to retain power.

  • The study demonstrates how paleogenomics can advance our understanding of historical societies and their social dynamics.

What is palaeogenomics

  • Palaeogenomics is the study of ancient DNA extracted from archaeological sites to understand historical populations and their development

  • It helps reveal details about past human societies, such as their migrations, cultural interactions, and genetic diversity

  • Scientists analyze DNA from ancient bones, teeth, or hair, and use advanced sequencing technologies to read and interpret these genetic codes.

Applications

  • Population Studies: Understand how ancient people migrated and mixed with other groups.

  • Cultural Insights: Learn about societal structures, health, and dietary habits.

  • Historical Reconstruction: Provide evidence to support or challenge historical records and legends.
