From ScienceDaily:
Scientists examining the multiple eyes found on the tentacles of fan worms have discovered they evolved independently from their other visual systems, specifically to support the needs of their lifestyle.
Fan worms live in tubes on the seafloor. From their heads, the worms extend feather-like tentacles up out of their tubes to sift the water for food particles and aid in respiration.
To protect themselves from predators, fan worms have evolved a variety of unusual compound eyes on their tentacles that act like shadow or motion detectors, alerting the worm to danger and triggering a rapid hiding response to encroaching objects in the water.
Superficially, some of these eyes resemble those of crustaceans or insects, but their photoreceptor cells are structurally and functionally distinct. Paper. (paywall) – Michael J. Bok, Megan L. Porter, Dan-Eric Nilsson. Phototransduction in fan worm radiolar eyes. Current Biology, 2017; 27 (14): R698 DOI: 10.1016/j.cub.2017.05.093 More.
Again, the question: What are the information resources that can be randomly assembled in order to produce such a result? Just because it would be useful is notan explanation of how,exactly it happened.
Darwinists invariably resort to bluster rather than calculation in these matters. That is why their paradigm is crumbling.
Note: David Berlinski’s take on Dan-Eric Nilsson’s approach is worth a look: A Scientific Scandal (on unbelieveable claims about eye evolution)
