'Lifelong monogamy' and 'half orphans': DNA analysis reveals clues about life on the Roman frontier after the fall of Rome
- New DNA analysis of 258 individuals from southern Germany (400–700 CE) reveals social patterns after Rome's fall.
- Researchers report lifelong monogamy and a high share of children who lost at least one parent by age 10.
- Life expectancy appears to have risen after the empire's fall, with men around 43 and women about 40 years.
- The study finds little evidence for polygamy or close-kin marriages in post-Roman society.
- Isotopic data and genomes indicate migrations northward and integration with local populations.
- The findings suggest social norms against divorce and remarriage persisted into early medieval times.
- Researchers note the study complements other work on post-Roman Europe and longevity trends.
- Experts compare results with earlier Roman-era life expectancy estimates to contextualize longevity.
- The study uses strontium isotope analysis to infer where individuals grew up.
- The work helps explain who lived on the Roman frontier and how communities restructured after Rome's collapse.
