On that level of savagery on which these European stocks began, and to which the several European racial types with their typical endowment of instincts are presumably adapted, men appear to have lived a fairly peaceable, though by no means an indolent life; in relatively small groups or communities; without any of the more useful domestic animals, though probably with some domestic plants; and busied with getting their living by daily work. Since they survived under the conditions offered them it is to be presumed that these men and women, say of the early neolithic time, took instinctively and kindly to those activities and mutual relations that would further the life of the group; and that, on the whole, they took less kindly and instinctively to such activities as would bring damage and discomfort on their neighbours and themselves.[69] Any racial type of which this had not been true, under the conditions known then to have prevailed in their habitat, must have presently disappeared from the face of the land, and the later advance of the Western culture would not have known their breed. Some other racial type, temperamentally so constituted as better to meet these requirements of survival under neolithic conditions, would have taken their place and would have left their own offspring to populate the region.[70] What is known of the conditions of life in early neolithic times[71] indicates that the first requisite of competitive survival was a more or less close attention to the business in hand, the providing of subsistence for the group and the rearing of offspring--a closer attention, for instance, than was given to this business by those other rival stocks whom the successful ones displaced; all of which throws into the foreground as indispensable native traits of the successful race the parental bent and the sense of workmanship, rather than those instinctive traits that make for disturbance of the peace.[72]
