We are therefore not astonished if some investigators simply assume that at first exogamy—both as to its origin and to its meaning—had nothing to do with totemism, but that it was added to it at some time without any deeper association, when marriage restrictions proved necessary. However that may be, the association of totemism and exogamy exists, and proves to be very strong.
Let us elucidate the meaning of this prohibition through further discussion.
