Summary

Story summary

Joachim Burger and colleagues published a Nature study showing genome analysis of row-grave individuals reveals diverse ancestry and gradual intermarriage, challenging a sudden barbarian invasion view.
Data show a north-to-south movement began in the third and fourth centuries with small kin groups.
Genomes reveal nuclear families, avoidance of close-kin unions, life expectancies around 40 years, and by the seventh century a new genetic profile that closely matches present-day central Europe.
