The genetic isolation of Papua New Guineans for millennia has revealed the presence of Denisovan genes, enhancing their immune system’s adaptability, according to a recent study. This finding underscores the profound impact of ancient human migrations on contemporary populations and highlights the resilience encoded in our genetic heritage.
