Social class reshapes genomes

The authors argue that socio‑economic status doesn’t just reflect genetic differences; over generations it feeds back on the gene pool through assortative mating, migration, and fertility patterns. This creates measurable genetic stratification aligned with social hierarchies without endorsing hereditarianism. — If social structure imprints on population genetics, debates over inequality, education, and 'nature vs nurture' must account for dynamic gene–environment feedback rather than one‑way causation.
