Perfectly true, but since developmental biology hasn't come to a
consensus about *any* of handedness ... this still begs the question of
*why*.

*most* is not *all*, or even *overwhelmingly*. Which is the
point. If it were 500:500, or 999:1, then there wouldn't be much of a
mystery. But since the ratio is more like 200:800 (and for the
fieldstaff at my work, 400:600 - figure that!), then it's a lot harder
to explain.
And I wouldn't be anything like as confident as you seem to be
about correlating right-handedness with right-eye dominance. Eye
dominance is considerable more evenly distributed than overt handedness
(which also tends to imply that the causative influences are not all
the same in handedness and eye-dominance).
