When groups of people live in considerable isolation, they tend to become physically homogeneous and adopt common ways of life. Their folkways extend into the details of their social customs and into the modes and styles of their material creations as well. Out of these customs and practices develop those institutions which have received the sanction of the group. The mores, customs, and institutions of a society are the particular topics of study of the sociologist. But the material devices of a social organization are equally important criteria of its culture and are, indeed, the only evidence that remains of a civilization after its promoters have passed away.
