Alien

A cuttlefish with glasses for 3-D
will strike at prey that isn't really there,
when shown a movie splitting red from green
as well as any falcon, snake, or bear.
Darwinian selection gave them eyes
quite independent of the orbs we sport,
and neural hardware that might theorize
'though manifestly not the chordate sort.

A parallel construction link by link.
Our common forebear couldn't have a mind
but cephalopods--somehow--learned to think.
Such good ideas recur, time and again
be it in motile molluscs, or in men.
