Children and subadults were obviously part of ancient human communities, and almost certainly, in important ways their activities were distinctive; they did not routinely act like scaled down adults. But their presence was quite cryptic, but not entirely hidden. Their lives and acts did leave traces, though these tend to be be fragile, ambiguous, and fast-fading. In addition to pursuing the methodological issues posed by the detection of subadult lives, this special issue raises important questions about the role of children, and their willingness to experiment and play, on innovation. It is true that ethnographically known forager children are almost certainly more autonomous, experimental, and adventurous than WEIRD children, and this was probably true of the young foragers of the early Holocene and late Pleistocene, too. Their greater willingness to experiment probably fueled a supply of variation, and perhaps occasionally adaptation as well, especially finding new uses for existing materials. Much more certainly, innovations tend to be noted, taken up, and spread by adolescents. They were vectors of change, even if perhaps only rarely initiators of change.
