Men generally are far more accurate with throwing objects due to evolution. I suspect this would spill over into bowling ability.
Some of us also have more trouble getting our hips out of the way.
having tried both the 10lb ball and the 16lb ball, i can confirm (anecdotally) that one of the difference is the deflection of the ball itself mentioned by Don Roberto.
putting as much force as possible behind the balls, the lighter one tends to deflect off despite hitting the pocket, while the heavier one will probably strike instead. (not to mention that the heavier ball gets a more satisfying strike sound. )
This, by far, is my favorite answer.
If only we could work in Remote Control Hogging into this thing called Evolution and how it applies to surviving all those years ago. [cue George Harrison Song]
Men evolved to be quick and speedy hunters, while women evolved to be patient and methodical gatherers. Slowly harvesting the subtleties of Oprah does not require the remote, while hunting for breasts and explosions does, because those are not regularly scheduled programs. (But they damn well should be.)
As for bowling, it’s the shoes. Ever since we let them stop being barefoot and pregnant, women have been obssesed about shoes. So we made bowling shoes as ugly as possible. This way, the fairer sex will worry more about their footwear clashing with their skirt than they will about the game, and men can retain our rightful superiority in hitting things with a heavier thing.
What did you expect? It’s a thread about bowling. Our minds are in the gu-
Nope, even I won’t make a pun that bad.

Except, it misfired a couple years ago when bowling shoes actually became a chic fashion statement for a while (much like surgeon’s greens a couple years before that). For a while bowling alleys actually had a problem with people leaving ratty old pairs of sneakers and walking out with the shoes (much like hospitals had a problem with people snitching surgeon’s gowns). “ugly” does not always reverse correlate with “fashionable”.
BTW, an interesting bit of trivia I stumbled across - 8 pound bowling balls float:

As with a lot of questions of this type, the real world efficacy of a particular weight of ball is not going to be illustrated by a simple answer from physics 101. There are too many complicating factors at work - the speed and accuracy with which a particular individual can roll a particular weight of ball isn’t simple to analyze, though you might find a fairly simple empirical model that fits. In general, one can suggest that the heaviest ball you can physically control well is probably best. A big gorilla of a guy that has the strength to control a 16 pound ball without straining himself has a certain advantage over an small woman who finds that 11 pounds is all she can manage, and that with difficulty.
Pin action is pretty much it. I added about 30 pins to my average just going up to a 16 pound ball.
Ten Pin Bowling is all about stringing strikes together. Picking up spares is wonderful but to compete on the pro tour you need to string those strikes. A heavier ball thrown with speed is going to create more pin action and not deflect as it goes through the pins. Pin action is going to result in leaving fewer splits and fewer 7/10 spares. Having the ball plow through the middle kicks out the 5 pin.
Lefties have traditionally had an advantage due to numbers. A small percentage of the population are lefties. So in any given field of bowlers you would have only a handful of lefties. At the beginning of a tournament the lanes are oiled. As the tournament progresses the righties will have carried more oil down the lane and have almost a dry channel to contend with. The lefties will not have as much oil carried down as quickly so they will have more consistent lane conditions over the course of the tournament.
This is why the professionals have so many balls. You have a strike ball for oily/medium/dry lanes and a spare ball for oily/medium/dry lanes as well as a straight ball for your corner pin spares. Your best bowlers adjust quickly to changing lane conditions.
