According to a recent acquaintance, a Ph.D. student of biology from Tufts University, there is a cockroach species that has become adapted to eating the plastic coating of electrical wiring. These resourceful bugs produce a particular enzyme specialized for the digestion of the electrical insulation material. For its proper functioning, this enzyme requires the heat that can be found in radio and television sets, computers, and many other kinds of electrical and electronic paraphernalia. Surprisingly, this species cannot live and reproduce in the absence of all these conditions. In other words, it must have arisen in the last fifty years or so. As cockroaches need less than ten days to reach maturity and reproduce, in this period there has been two-to-three thousand generations of these remarkable insects, continually adapting to their ever more complex environment. Considering the fact that Blattaria are among the oldest creatures on this planet, it is hard to imagine that they can ever be beaten in the evolution game. God bless them, the most likely heirs of our civilization.
