SO ENDS this second weekend on the termite mound, its construction, and repair. The author has delved very deeply into this structure. Most notably, he has concluded that it is built out of species exuberance, and has signs and symbols of coded hive memory sufficient to survive short worker lifetimes. While it has adaptive significance for humidity control, its interpreted metasignificance is quite stunning; one cannot help looking at our own spires as a type of species exuberance. The insights into the intimacies of the grooming ritual are equally compelling. A wonderful article about the superorganism.
