[QUOTE]Originally posted by Swenet: [QB] [QUOTE]Originally posted by the lioness,: Later into this process we see these "random" mutations occurring in the group lead to non-"random" outcomes, outcomes that the species as a whole starts to become better "designed" [/QUOTE] [QUOTE]Originally posted by the lioness,: So how can anyone one call such a process "dumb" when the result is ever improving "design" ?[/QUOTE] [QUOTE]Originally posted by the lioness,: "spontaneity" doesn't happen in isolation. In a broader context it has "purpose"[/QUOTE]Prove with examples that adaptations are necessarily preserved over time and accumulate to produce complexity in a consistent way. Until you can give examples I'm not wasting my time arguing you on this topic. I can corroborate what I'm saying. Can you do the same? In the grand scheme adaptation is an anti-complexity ('dumb') process that pushes organisms to evolve in all sorts of directions (including 'back and forth'), depending on the selection pressures. It's 'dumb' because it's anti-complexity, not because I'm denying it helps in survival. However, any benefit is only relative to the 'short-lived' environmental pressures. There is no evidence that adaptation is accumulative in the sense that it consistently leads to complexity. Can you prove otherwise? [QUOTE]Evolution can be predicted in the short term from a knowledge of selection and inheritance. [b]However, in the long term evolution is unpredictable because environments, which determine the directions and magnitudes of selection coefficients, fluctuate unpredictably.[/b] These two features of evolution, the predictable and unpredictable, [b]are demonstrated in a study of two populations of Darwin’s finches on the Gala´pagos island of Daphne Major. From 1972 to 2001, Geospiza fortis (medium ground finch) and Geospiza scandens (cactus finch) changed several times in body size and two beak traits. Natural selection occurred frequently in both species and varied from unidirectional to oscillating, episodic to gradual. Hybridization occurred repeatedly though rarely, resulting in elevated phenotypic variances in G. scandens and a change in beak shape.[/b] The phenotypic states of both species at the end of the 30-year study [b]could not have been predicted at the beginning.[/b] Continuous, long-term studies are needed to detect and interpret rare but important events and nonuniform evolutionary change.[/QUOTE] http://science.sciencemag.org/content/296/5568/707.full Adaptations are tweaks relative to the highly unpredictable environment, not to some ideal like "better design" or "complexity" or "intelligence".
