tuations in climatic parameters and atmo~i~ric circulation, the Moon's nutation cycle, and the cyclone-scale waves and planetary waves affecting the stratosphere is reviewed. Evidence is accumu- latin 8 which suggests that solar variations and lunar tidal forces can produce small-scale weather changes detectable in long-term cycles. (hbf)

Michael Ruse, a philosopher, defends Darwinian theory against critics who claim that the theory is not genuine science because i t is not falsifiable and that the process of natural selection is tautological and empirically empty. Mark Ridley, a zoologist, points out that contrary to recent publicity, paleontologists do not doubt the validity of evolutionary theory and that speciation di~.ernible in the fossil record is not part of the evidcacv for evolution. The theory is supported instead by observed evolution of species, biogeography, and the hierarchical structure of taxonomy. Univ. of Guelph, Ont., Canada. (mjj)

'The "hypothesis of formative causation" enables the regularities of nature to be regarded more as habits

l ' than as reflections of timeless sws. Central to this hypothesis is the idea of a " m o ~ o g a e t i c field' which can cause a trend to ~ or organizational similarity elsewhere through "morphic resonance' of similar, but yet to be organized, components. It is supposed to dodge the assumption that bu ic principles exist outside of (beyond) the media in which they ate evidenced. (fcs)
