I expect the difference has more to do with the difference in motion-correlated G-forces experienced. On land, the eyes are 'hammered' with every step one takes [shock wave absorption is a necessity]. Anyway, I find evolutionary dynamics to have their own 'intelligence' in that they 'read' the environment, and converge upon functionality that works in that environment. It's why one has to be careful when attempting to cross-correlate the products of evolutionary 'engineering' with respect to different environments. Unless there's non-modal stuff in there, both are 'intelligent', but only with respect to the environments in which their progenitors have evolved. The rest of the "creationism/evolution" 'debate' is just folks being prejudiced with respect to that which, through experience, they've become familiar. k. p. collins Kent Paul Dolan wrote in message ... |jmdrake_98@yahoo.com (jmdrake) wrote: | |> Actually Bernd there is an "obvious reason" to do this.

If there were a |Designer, apparently the "Intelligent" aspect faded in and out pretty |often, a total contradiction to claims of omniscience and |omnitemporalness.
