Some biologists doubt that springtails should be classified as true insects. In any event, these ancient springtails are considered too specialized to be the ancestors of modern winged insects. The next insects in the fossil record appear suddenly in the Upper Carboniferous (300 million years ago) with fully developed wings. There exists an embarrassing 50-million-year gap between the fossil springtails and the more specialized insects. Evolution requires that this gap be filled with many random experiments at insect construction, including the first attempts at fashioning wings. Whalley admits the gap and the total mystification of paleontologists about how insects and biological flight first developed. Perhaps, he surmises, wings may have been the natural extrapolation of flap-like outgrowths required for body cooling. Random mutations would have added the muscles needed to orient the flaps and move them to improve circulation! (Whalley, Paul; "Derbyshire's Darning Needle," New Scientist, 78:740, 1978.)

... competing "interpretations" of quantum mechanics, none of which is completely convincing. No wonder, because quantum mechanics implies four characteristics of the universe that are seriously at odds with our everyday experience: The quantization of the properties of matter; The probabilistic nature of physical measurements; Entanglement; that is, the mysterious instantaneous connection of objects and processes across immense distances; and Superposition; for example, an electron is both here and there until we look at it! A. Zeilinger, University of Vienna, advances the idea that we can truly understand quantum mechanics only when we discover an underlying principle -- something akin to the concept of energy which led to the quantification of the laws of thermodynamics. (Incidentally. we only think we know what energy is, but it is a human construct and is not a physical dimension like mass or distance.) Zeilinger asserts that the underlying principle of quantum mechanics is the quantization of information. Every inquiry science makes into the nature of the universe, says Zeilinger, can be reduced to a yes-or-no question; i.e ., a 1 or 0. To a scientist, nature is really like a person on a witness stand being hammered by a prosecutor (i .e ., a scientist) with yes-or-no questions. In other words, nature appears quantized because our knowledge of it is quantized. (von Baeyer, Hans Christian; "In the Beginning Was the Bit," New Scientist, p. 26, February 17, 2001.) Comment. It follows, we ...
