To be sure, corals built the Great Barrier Reef and beavers left their mark on the hydrology of parts of Canada and the U.S .; but termites!? It seems that in southern Africa this industrious insect is responsible for enormous striped patterns of ridges and vegetation bands. These amazingly regular patterns are caused by alternating low ridges and gullies. The ridges are about 2 meters high, up to a kilometer long, and separated by about 50 meters. The ridges themselves are closely spaced termite mounds. Just why the termites ... to build their mounds in long rows is an unanswered question. And how do the termites maintain strict parallelism, especially since they are blind? How could termites in one mound know how their neighbors in the nearest ridge, 50 meters away, are building their mounds? Anyway, the ridges help channel the flow of water and thus the growth of vegetation, giving immense swathes of country a corrugated appearance. (Sattaur, Omar; "Termites Change the Face of Africa," New Scientist, p. 27, January 26, 1991.) Comment. In Australia, the so-called "magnetic" termites build their slab-like mounds so as to minimize the amount of sun-generated heat. From Science Frontiers #74, MAR-APR 1991 . 1991-2000 William ...

Termite mounds are often mentioned as superoganisms. But here we examine colonies of organisms that are much simpler and much smaller than termites. What entices the anomalist to attend to superorganisms? Here are two of the several questions superorganisms raise. How do superorganisms evolve properties that its constituent individuals do not possess, such as mobility, unique sensors, and even a modicum of intelligence. Since superorganisms do not reproduce as superorganisms, how can natural selection operate on these superorganisms? Salps. ...
