Yet, as has been remarked, the earliest families might be simple and innocent, while at the same time unskilled and ignorant, and obliged to live merely upon such substances as they could readily procure. The traditions of all nations refer to such a state as that in which mankind were at first: perhaps it is not so much a tradition as an idea which the human mind naturally inclines to form respecting the fathers of the race; but nothing that we see of mankind absolutely forbids our entertaining this idea, while there are some considerations rather favourable to it. A few families, in a state of nature, living near each other, in a country supplying the means of livelihood abundantly, are generally simple and innocent; their instinctive and perceptive faculties are also apt to be very active, although the higher intellect may be dormant. If we therefore presume India to have been the cradle of our race, they might at first exemplify a sort of golden age; but it could not be of long continuance. The very first movements from the primal seat would be attended with degradation, nor could there be any tendency to true civilization till groups had settled and thickened in particular seats physically limited. The probability may now be assumed that the human race sprung from one stock, which was at first in a state of simplicity, if not barbarism. As yet we have not seen very distinctly how the various branches of the family, as they parted off, and took up separate ground, became marked by external features so peculiar. Why are the Africans black, and generally marked by coarse features and ungainly forms? Why are the Mongolians generally yellow, the Americans red, the Caucasians white? Why the flat features of the Chinese, the small stature of the Laps, the soft round forms of the English, the lank features of their descendants, the Americans? All of these phenomena appear, in a word, to be explicable on the ground of _development_. We have already seen that various leading animal forms represent stages in the embryotic progress of the highest—the human being. Our brain goes through the various stages of a fish’s, a reptile’s, and a mammifer’s brain, and finally becomes human. There is more than this, for, after completing the animal transformations, it passes through the characters in which it appears, in the Negro, Malay, American, and Mongolian nations, and finally is Caucasian. The face partakes of these alterations. “One of the earliest points in which ossification commences is the lower jaw. This bone is consequently sooner completed than the other bones of the head, and acquires a predominance, which, as is well known, it never loses in the Negro. During the soft pliant state of the bones of the skull, the oblong form which they naturally assume, approaches nearly the permanent shape of the Americans. At birth, the flattened face, and broad smooth forehead of the infant, the position of the eyes rather towards the side
