"In the meantime, the movement of genes between unrelated organisms was discovered. It would appear that horizontal/lateral gene transfer (HGT/LGT) plays a far more important role than point mutation of genes in situ. As an example there's a cnidarian (jellyfish) with perfect lenses, but lacking the necessary retina and brain to process visual information."
According to some articles I've read in Nature, the lenses still serve a purpose though not in the way we use eyes.
