your main hand is the opposite of the testicle that hangs low.
This allows optimal scratching and sniffing, it's an evolutionary advantage.

Not proven, but a popular hypothesis:

There is a combat advantage to being left-handed. If you are left-handed, most of your opponents will be right-handed, and you will be used to how they move. But most of your opponents' opponents will also be right-handed, so they WON'T be used to how you move. This is most commonly observed today in sports.

This would create a kind of equilibrium, where the advantage is bigger the rarer it is, which in turn makes it more common, etc. If left-handedness also comes along with certain disadvantages (and there is evidence it does, healthwise), then you end up with stable minority of left-handers.

Being left handed myself I could say that is spot on. Though one person is far from a proof

Southpaw boxer here. Can confirm there is a huge advantage.
I am still curious as to why left handedness has remained so stable at 7-10% of the population.

Yes this makes sense and this kind of equilibrium has been observed in nature.

There was a good video about this but I can't find it on YouTube.
However, we are not yet sure that being left handed has anything to do with genes.
