Los elefantes marinos del norte tienen poca variabilidad genética, probablemente, por un proceso que le hicieron pasar los hombres en la década de 1890. La caza hizo disminuir el censo poblacional hasta tan sólo 20 individuos a finales del siglo XIX. Desde entonces, su población ha «rebotado» hasta más de 30 000, pero sus genes todavía llevan las señales de sus aquellas generaciones su variabilidad genética es mucho menor que la de una población de elefantes marinos del sur que no sufrió una caza tan intensa. Este proceso puede denominarse como:
