A recent in-depth study has used DNA analysis to reveal some intriguing information about sex and marriage patterns within an ancient empire. Researchers have analyzed genetic materials from individuals who lived in different parts of the empire to determine their familial relationships and ethnic lineage.
The study showed that marriages were often arranged among individuals from the same ethnic groups, contributing to preservation of specific gene pools. This indicates a strong endogamy pattern, where marriage within a particular social group, class, or ethnicity was favored.
Moreover, it was uncovered that social hierarchy was likely to influence marriage arrangements, with upper-class individuals having partners from the same societal tier. Interestingly, genetic diversity in the ruling class, lower compared to the general population, suggests intermarriage among the elites.
As for patterns of sex, a very low gene flow among groups implies strict rules around relationships and intercourse. These rules possibly penalized or forbade extramarital sex, thereby preventing the intermingling of genes across different social or ethnic groups outside of marriages.
Such studies help scientists and archaeologists gain valuable insights into the social structure and dynamics of ancient civilizations. They provide a window to see how family life, social mobility, and group identity were maintained and reinforced in the past, thereby informing our understanding of history and our evolutionary journey as a species.
