← The Eyes of Richard Dawkins

Eyes may have evolved separately a number of times but all from a single source.

Life as we know it is all DNA based and came from a single past ancestor and shared the same environment. So I cannot see how anyone can make the statement that eyes will probably show up on all advanced alien lifeforms when all the constants that brought eyes into being will at the very least be slightly different in alien life.
