Therefore, if there were bacteria on Mars whose organization and ecology were identical to ones on earth, but there was no evidence that they both descended from the same stock, we would not say that they were the same bacteria Mayr, 1988, p.343.
Por eso, si en Marte existiese una bacteria idéntica en su organización y ecología a una bacteria terrestre, pero no hubiese evidencias de que ambas bacterias descienden directamente de una misma cepa, no diríamos que es la misma bacteria Mayr, 1988, p.343.
