Take a look at the Ant galaxys, two sprial which on their first pass have
torn gas/dust out and way and there's major star forming there, they will
return on the next go around and most likly end up floming a larger spiral
galaxy as their two Black Holes mearg into one Black Hole.

Look at todays hubble news, galaxys that had formed just about 1 billion
years after the big bang and so far they've counted 500 of them just from
one area, take that 1 degree slick and figure out the other 59 dregrees
worth and the number of galaxys becomes mind staging.

dribble thusly:

And in another billion years, our galaxy and M-31 will start the dance of
death and will endup sometime in the far furture mearing together to
become
a vastly bigger spiral galaxy.

Actually, all the models I've heard of predict that two large spirals
always create an elliptical when they merge.
