The Moth in Spider’s Clothing

National Geographic News has a picture story about a moth that mimics a jumping spider.  It appears to work.  Scientists staged a battle royale between contestants of mimics and non-mimics in the ring with their jumping spider enemies, and the mimics won hands down.  The spiders went for the normal moths 62% of the time, but backed away from their mirror-images, the moths in spider clothing, in all but 6% of cases.  The fooled spiders even made aggressive territorial displays against some of their mimics.  The metalmark moths of Costa Rica flare up their wings and make a spidery pose when threatened.  A somewhat similar strategy is recommended for humans when facing a mountain lion.

Mimicry is a common occurrence in nature.  Evolutionists explain this as a result of natural selection, and it is, but not in the macroevolutionary sense Darwin needs.  These moths already have wings, legs, and sophisticated pigmentation software.  If Darwin had discovered a deterministic law, all species would follow this strategy, and every prey would look like its predator.  If the non-mimic moths had the same amount of evolutionary time, why did they remain behind?  Didn’t they learn the Darwinian lesson?  And if the predators also had the same time, why didn’t they catch onto the trick?
    Horizontal changes can occur rapidly under sufficient predation pressure or competition (cp. 02/26/2007 with orchids).  A population of dogs isolated in the Arctic will favor long-haired survivors if the genes for long hair already exist.  A population of desert plants will favor those able to reach deep if the genes to do so already exist.  Find a moth that evolves a machine gun via slow, incremental steps and creationists will take notice (requirement: all the intermediate forms must be found, too).
Suggested new book:  A medical doctor, Geoffrey Simmons, has just completed a new book Billions of Missing Links (Harvest House, 2006).  It is loaded with examples of clever and sophisticated designs in nature that could never have evolved by gradual evolutionary steps.
