My simple idea...
If throughout history there was even only a slight imbalance in favour of right-handedness, then could just simple conflict and combat be a
fundamental factor?
For example hand weapons - say were talking about when were about 'cave man' age, you know clubs rocks simple axes... So from that point forward,
hunting for food aside (although that would closely tie in here) humans will come into direct one on one combat with each other - Territory, power,
dominance, survival and just cos cave men were jerks...
Now we all know our fickle female counterparts (
) Will usually favour a male that wins in combat over a looser (especially studies have shown
for a first born child's farther... They would naturally want a strong man around as they are young and new to the world, and strong first offspring
to defend and hunt while more offspring come along - a pregnant woman is at a disadvantage should the camp get raided or from predators... After the
first born women can relax this instinct and may look for other traits)....
Simply put Henry the cave man pummels Francis over the last zebra steak... He does this week in week out.
Now 1) If this keeps happening Francis only ever gets to suck the Zebra bones for food, and 2) Well the women just love Henry, he's getting bigger
and bigger, stronger and stronger - all the women want him in their cave cos he gets all the Zebra steaks, as soon as the sun goes down Henry goes a
cave hopping while Francis has to write poetry to get laid!
Now simple numbers over history will dictate that if nature favoured right handed people for whatever reason, maybe simple chance... The numbers will
have filtered down to the present day... This is why we see a dominance.
Of course when real culture and later mass education start training this into kids mentioned above - well they are simply extending an engrained
perceived advantage. - Sometimes a family will send one kid away to a church or something to study, while another becomes a blacksmith or a farmer
etc - which son do you think will have the most off spring?
Also lefties cant use can openers so they go hungry
