Is being left handed heredity?  Is it something in our brain that we choose to write with this hand.?

I believe that I was taught it is genetic... your mother or your father have the gene and pass it to you... they don't have to be a lefty... only have the gene

Lefties tend to be more artistic since they use the right side of the brain.  Right handed people tend to be better with analytical issues since they use the left side of the brain.  There are less left-handed than right-handed people, but that makes them more special!! =o)

Two things come to mind...\n\nAnything that required two hands such as shampooing your hair, tying shoes, washing dishes, cutting food, etc.\n\nIt would also be hard to write legibly if you are not ambidextrous.

Hmmmm ... it's difficult to say.  Maybe people who are left handed are smarter since they have to learn to cope in a world made for right handed people.  \n\nWhile there is an unresolved debate within the scientific community on how to operationalize both intelligence and creativity, some studies have demonstrated a small positive correlation between left-handedness and creativity/intelligence.  In his book Right-Hand, Left-Hand, Chris McManus of University College London, argues that the proportion of left-handers is rising and left-handed people as a group have historically produced an above-average quota of high achievers. He says that left-handers' brains are structured differently in a way that widens their range of abilities, and the genes that determine left-handedness also govern development of the language centres of the brain.\n\nI hope this helps.

A person who is left-handed primarily uses their left hand, more so than their right hand; a left-hander will probably use the left hand for tasks such as personal care, cooking, and so on. Writing is not as precise an indicator of handedness as it might seem, because many people who are left-handed write with their right hand and use their left for everything else.\n\nPeople who are left-handed are technically said to be sinistral, and left-handedness is sometimes referred to as sinistrality. Both words derive from sinister, the Latin word for “left”. This word in turn derives from sinus, the Latin word for “pocket” referring to the fact that the pocket in a Roman toga was on the left side, for the convenience of a right-handed wearer\nStatistics of left-handedness\nApproximately 10% of the population is left-handed. People who can use both hands equally well are ambidextrous. True ambidexterity is rare. See laterality.\n\nGenerally, there are about 10% more male left handers than female left handers (5.24% Male, 4.76% Female). Approximately one-third of identical twins are left-handed. [1] Statistically, the twin of a left-handed person has a 76% chance of being left-handed. [1]\n\n[edit]\nCauses of left-handedness\nNo one knows for certain why the human population is right-handed-dominant, but a number of theories have been proposed.\n\n[edit]\nEvolutionary theories\n[edit]\nThe warrior and his shield\nThis theory attempts to explain why left-handedness is rare by the position of a warrior's shield and his heart. Basically, since the heart is on the left side of the body, a right-handed warrior (who holds his shield with his left hand to free the right hand for a weapon) would be better able to protect his heart and therefore more likely to survive.\n\nThere are a number of objections to this theory:\n\nThe heart is not that far off centre. Protecting it with a shield would result in a weak selective pressure. \nThere have not been enough generations since the Bronze Age to make a difference. \nAnalysis of ancient cave paintings [2] indicates that humanity was dominantly right-handed long before the Bronze Age. \nSome believe it predicts that more men would be right-handed than women. However, data indicates that more males are left-handed than females. This objection also demonstrates a misunderstanding of heredity. The theory would predict that fewer left-handed males would survive but says absolutely nothing about ratios of male: female left-handedness after that time. Nor does it explain why there would be either right-or left-handedness to begin with. \n[edit]\nAdvantage in fist-fighting\nA variant of the above argument says that left-handed people have an advantage in fighting without weapons, because of the "surprise" factor. (This fact is well known to boxers and was employed to world-record effect on Nov. 4th 1947 when Mike Collins, a natural left-hander, emerged from his corner in a right-handed stance before suddenly shifting left and delivering the fight's first and last punch, knocking out opponent Pat Brownson in 4 seconds.)\n\nA 2004 study by Charlotte Fauriet and Michel Raymond of the University of Montpellier II in France, published in the Proceedings of the Royal Society, argues that there is such a link. To prove their theory, Faurie and Raymond surveyed nine primitive societies in five separate continents. Through a mix of direct observation and existing data, they estimated the number of left-handed people within each population. They also looked at murder rates, thinking that those communities with higher murder rates might favor populations with more left-handed people. The more violence, the more chances lefties would have at issuing their unexpected left hook, or other such weapon, and come out on top.\n\nAmong these samples, they found strong support for the idea that, at least in primitive societies with higher levels of violence, lefties thrive.

Handwriting is not controlled by just one part of the brain. It involves many parts. Language, muscle movement, imagination, creative activity etc

1. Writing sucks. Wether it be pen or pencil, it's still getting all over us.\n2. Using someone else's mouse. It's almost always on the right hand side so I have to use my right hand. \n3. If sitting next to a righty while eating, you have to sit on the left hand side otherwise you'll wack elbows.\n4. Writing on the windshields of cars, we just can't do it on the passenger side, or it will be sideways (I work in a car dealership and I can never do that cuz of this reason)\n5. Sissors! It's nearly impossible to cut with your left hand!!! Gah\n6. Coffee mugs. The image is always on the inside, instead of the outside (but i guess that's good since you'll be able to see it :)) \n7. I can't think of any others, so I'll write 2 good things. They say that the left side of your brain controls the right side of the body and the right side controls the left side, so lefties are in their right minds ;)\n8. We're all Southpaws!! When do righties ever get comments on which hand they write with??? Lefties rule! :D\nIf you wear a belt that has a buckle, like a Lion Head, it's upside down to a lefty. So odd. But I love it. \nWHat a good question!!

The right side of the brain controls the left side of the body. It's also responsible for controlling imagination and creativity so the answer to your ? is yes. South-paws tend to be more creative and intuitive. I don't know so much about brilliant, though. Many of the greatest minds throughout history were housed in right-handed bodies.

As I was taught (and don't quite believe entirely) is that left handed people tend to use more of their right hemisphere than right handed people.  The right brain is supposedly the more "creative" brain rather than the left sided "logical" hemisphere.  Studies do show that left handed people tend to use both hemispheres for communication rather than a dominated left hemispheres.  There is actually an increase of left handers in the "creative" occupations like painting and music.

My husband is left handed and plays awesome...he teaches a lot of other people how to play! So hes pretty good...lol\n\n-Lorah

Right handed.  I noticed that left handed people tend to be better artists than us right handers.....

Amongst the equipment in my lab. for science classes I kept at least 5 pairs of left-handed scissors. Many left-handers were delighted to be able to use scissors so much more easily. I still have trouble with many DIY tools which have to be used right-handed - but as you say, left-handers do become more ambidextrous.\n\nThe following links might interest you:

Your teacher was probably referring to ambidextrous people (im able to write, do anything actually with both hands, legs etc.) true ambidextrous people, not people that teach themselves how to do it think differently to just right handed or left handed people. Apparently i can switch my thinking to either side of my brain, over all i tend to have a "center" of thinking.  i can also read backwards and write backwards or with both hands at the same time without even thinking about it. I discovered this when i was a teenager, all my friends thought it was awesome and tried to do it! i thought it was so funny because they were all trying so hard when i didnt even have to think when i did it! \nI'm not sure if im smarter then other people, maybe i am lol! i did always get great marks in school so yer, but there are disadvantages-always have had trouble working out left from right, learning languages, trouble with figures/maths in general. All of those disadvantages are proven.\n\nYou cannot make yourself be left handed or ambidextrous and get the positives with it-like being intelligent (so they say).\nSo dont try to be, you cannot change how your brain works. \nHope this helped.

depends on what type of person you are.\n\nIf you are linear, logical, and you remember things using numbers or logical orders then you use the left side.  \n\nIf you are a very creative person and you remember things using pictures or symbols then you are using the right side of your brain.

Sounds to me like you have a  mental block. We all have different strenghts and weaknesses. I know I am horrible at math, but I kick butt in astronomy/cosmology and I read very, very fast. Also I can't draw worth a damn but I've won awards for my writing. Also, I am very good with problem solving and logicl problems. By the way I'm right handed.\n\nTo see different things that the left/right brain affect/control check out: \nhttp://www.viewzone.com/bicam.html\n\nhttp://www.funderstanding.com/right_left_brain.cfm\n\nhttp://brain.web-us.com/brain/LRBrain.html this one lets you take a test to see if your left or right side dominant

Approximately 10% of the population classify themselves as being left-handed, with the percentage slightly higher for males and lower for females (McManus, 2002). Faurie and Raymond (2004) reviewed handedness frequency over more than ten thousand years (the oldest evidence coming from Palaeolithic ‘negative hand’ paintings), and determined that there was no difference between the oldest sample and the proportions found in university students today.\n\nHope that helps!

actually I am ambidextrous (left handed and right handed)\n\nand yes i think there will be a lot of bible bangers answering you and i hope they don't report you, @ssholes\n\n\np.s. I’M AN ATHIEST!!!!!
