Bombardier of the Sea

Creationists have made much of the bombardier beetle (#1, #2) whose firing chambers would explode if the timing and mixture of ingredients did not work perfectly together.  Now, here is a similar case in the lowly sea slug.  EurekAlert described research by Georgia State University scientists, who found that the sea slug Aplysia mixes three inert ingredients to produce a sticky secretion, dyed purple, for defense:

“Aplysia packages these innocuous precursors separately and then releases them simultaneously into its mantle cavity at the precise time when they are needed,” explained [Charles] Derby.  “This mechanism insures the secretion’s potency against attacking predators to enable sea slugs to escape.”   (Emphasis added in all quotes.)

The secretion seems to contain a healing compound.  “The antimicrobial property probably evolved to work against predators,” said Derby.  “But it might also function as an antimicrobial salve for Aplysia’s own wounds.”

The evolutionary mythoid contributes nothing of substance to this story.  On grounds of intellectual honesty and scientific integrity, we need to call Darwinists on the carpet for simply claiming evolution blindly made irreducibly complex systems without telling us how.  This is more of the BAD strategy (bluffing assertions of dogmatism) that lets Darwinians escape while secreting a sticky dyed goo that obscures understanding.
