“If natural selection is reactive and blind, how do we explain anticipatory adaptations — such as toxins, thorns, camouflage — evolving with such precision before extinction wipes out the vulnerable lineage?”

@Heavenlywarrior They are not anticipatory. The do not evolve with precision, most species that ever lived are extinct. Your argument is called irreducible complexitity. Like how can a bird have half a wing? Well evolution works in small increments.

@JimboSaturn You said traits evolve ‘in small increments.’ But why would an organism persist in developing half a function — like a partial wing or partial eye — if that trait has no advantage yet?

@Heavenlywarrior Google Richard Dawkins explain evolution of the eye. Small increments can be advantageous like photoreptors located in one spot first, then the structure slightly concave would focus the image and give an advantage, each small step an improvement over the other until an eye as we know it is evolved. Many other examples are available, fins that can act as flippers and moved a fish on land briefly from one shrinking pool to a larger water mass, slight wings like flying squirrels could allow an animal to glide from one tree to the next. The argument you are using is irreducible complexity.
