Recent research shows how our genes
can adapt to the introduction of a new diet. This is evidenced in the study
conducted in European populations where researchers investigated how the
dietary transition from animal-based diet to plant-based diet (during the
agricultural revolution) in European populations resulted in the selection of
adaptive alleles. Using analysis on ancient and modern DNA, they found positive
selection on opposite alleles of the same variants. This
genetic evidence makes implication of dietary variation among human population
throughout the time.
