Eli5:what’s the cause of someone being right or left handed? And why the vast majority is right handed?
In: Biology
I’m a lefty. I suck at art. I’ve noticed over the course of my 65+ years that for some reason I don’t seem to process information or react to some situations like most people do. I’ve grown to accept that I’m just different. Not better, not worse. Just a beat or two off the usual rhythm of life.
> what’s the cause of someone being right or left handed?
Because people to first interact with them are right handed or left handed so they mimic them.
> And why the vast majority is right handed?
Because doctors who deliver babies tend to be right handed.
Also, left handed people are more creative because the world is right handed thus they are forced to think outside the box to do even the simple things in life.
So if the world was left handed, the right handed would be the creative ones instead.
I’m a lefty. My mom is a lefty and her father was also a lefty. My father is also a lefty lol. I’m a graphic designer and my mom is super artistic as well. So there’s got to be some genetic component involved.
Since there are rare fetal malformations impacting limbs, what happens if a right handed fetus looses function in the right limb?
Obviously they adapt, but is the ceiling lower on their dexterity than if they had been a left handed fetus in the same situation?
I am a lefty that does some right handed things like throw (taught to throw) but not kick ( more innate it seems). i bat right and play golf (taught but also no way we could afford two sets of golf clubs so dad and I shared and he had right-handed clubs.)
My hand0writing is not good but I can print pretty good right handed, neater but slower. I can also print upside down pretty, pretty, pretty good, and I though everyone could do that but it seems to not be the case as when I did this in front of people on a white board everyone was like, “WTF?”.
So how many lefties can write upside down with ease?
I can’t quote the study, but back in 1990’s I read it had something to to with when you were a 3 month old fetus & a surge of testosterone.
That’s why there’s more left handed male people than female.
