Anomalies are the driving force behind scientific revolutions; they stand out against the backdrop of accepted scientific belief, driving new conceptual schemes and paving the way for yet more discoveries. It is hard to imagine a discovery of greater significance to science than a shadow biosphere of weird life on Earth. There is, of course, no guarantee that such a biosphere exists or has ever existed. But a systematic search for one, even if unsuccessful, is a worthwhile strategy anyway, if only because it may very well uncover hitherto unknown highly exotic forms of standard life.»
