The maintenance of life, through the constant acquisition of food, is the great burden imposed upon existence in all species of animals. As we descend in the scale of structural organization, subsistence becomes more and more simple at each stage, until the mystery finally vanishes. But, in the ascending scale, it becomes increasingly difficult until the highest structural form, that of man, is reached, when it attains the maximum.
Intelligence from henceforth becomes a more prominent factor. Animal food, in all probability, entered from a very early period into human consumption; but whether it was actively sought when mankind were essentially frugivorous in practice, though omnivorous in structural organization, must remain a matter of conjecture. This mode of sustenance belongs to the strictly primitive period.
II. Fish Subsistence.
In fish must be recognized the first kind of artificial food, because it was not fully available without cooking. Fire was first utilized, not unlikely, for this purpose. Fish were universal in distribution, unlimited in supply, and the only kind of food at all times attainable. The cereals in the primitive period were still unknown, if in fact they existed, and the hunt for game was too precarious ever to have formed an exclusive means of human support. Upon this species of food mankind became independent of climate and of locality; and by following the shores of the seas and lakes, and the courses of the rivers could, while in the savage state, spread themselves over the greater portion of the earth’s surface. Of the fact of these migrations there is abundant evidence in the remains of flint and stone implements of the Status of Savagery found upon all the continents. In reliance upon fruits and spontaneous subsistence a removal from the original habitat would have been impossible.
Between the introduction of fish, followed by the wide migrations named, and the cultivation of farinaceous food, the interval of time was immense. It covers a large part of the period of savagery. But during this interval there was an important increase in the variety and amount of food. Such, for example, as the bread roots cooked in ground ovens, and in the permanent addition of game through improved weapons, and especially through the bow and arrow. This remarkable invention, which came in after the spear and war club, and gave the first deadly weapon for the hunt, appeared late in savagery.[10]
It has been used to mark the commencement of its Upper Status. It must have given a powerful upward influence to ancient society, standing in the same relation to the period of savagery, as the iron sword to the period of barbarism, and fire-arms to the period of civilization.
From the precarious nature of all these sources of food, outside of the great fish areas, cannibalism became the dire resort of mankind. The ancient universality of this practice is being gradually demonstrated.
