they can control their environment by utilizing the laws which govern
universal evolution.

From this brief and most elementary consideration of the bearings of
evolutionary theory upon social problems it is evident that evolution,
in the sense of what we know about the development of life and society
in the past, must be the guidepost of the sociologist. Human social
evolution, we repeat, rests upon and is conditioned by biological
evolution at every point. There is, therefore, scarcely any sanity in
sociology without the biological point of view.
