If we assume for a second that silicon life is a thing, would it be reasonable to think that it would be utterly alien? Probably it's chemical composition would be entirely different, but would it be unreasonable, that it could evolve eye, muscle, bone etc. analogs just like us, and the end result would be not entirely unfamiliar to our earthly eyes? The article talked about wings being one of the few viable modes of flight, and Richard Dawkins has made a lecture about eyes having evolved independently multiple time here on earth (like in, as the article states, mammals or octopi).
