The point was that molluscs are not eyeless, the cephalopod
eye being classically given as an example of convergent
evolution. But one of the most
interesting genetic discoveries of the last 10 years was that
there is a conserved homeobox gene Pax-6 in mice, eyeless in
drosophila, aneridia in humans etc, that induces the development
of eyes in all metzoans, thus rather than being convergent
share a common genetic determination with our own.

I was constructing an analogue of your argument in
a different domain from which a demonstrably false
conclusion could be drawn.
