Then how can we account for butterflies that mimic wing coloration Of toxic counterparts to ward off birds.Evolution is not blind, we just have not figured out the feedback mechanism yet, most likely its some kind of genetic memory.
$living_thing with $property (wing coloration) is dead before reproduction happens, $property may not be transmitted to the offsprings.
It's a simple enough concept at its core. Then comes the complications of mutations, random this and that.
what is your evidence for this claim?
when you say "how can we account for butterflies that mimic wing coloration Of toxic counterparts to ward off birds" there's no reason to suppose the development of that would need to be directed.
