RE: Questions about evolution?
Some sea stars (star fish) have a primitive eye on each arm, and although they have a no brain have now been proven to "see" in order to navigate towards a food-rich reef. This is one of the simplest eyes known in nature and is thought to be similar to the first eyes. Light-sensitivity of cells and the ability of an organism to transmit this information to other cells to make decisions useful to survival may have occurred before we diverged from the sea star line. Once the mechanism exists natural selection can work to make improve vision over subsequent generations and in various ways.

I think most if not all senses are understood to have been established in very early species and that they have subsequently been refined and honed through natural selection.

Give me your argument in the form of a published paper, and then we can start to talk.
