Wonderful. Hopefully the left handed can be cured with gene therapy instead of being rounded up and sent to work camps as some have suggested.

A series of new studies show that left-handed people are more likely to suffer from learning disabilities, stuttering, migraine headaches and, according to the latest findings, autoimmune diseases, like ulcerative colitis, myasthenia gravis and celiac disease, in which the body attacks its own tissues.

when i was a kid, a friend of mine from across the street was lefthanded but had a mom who forced her to behave righthandedly. as a consequence (according to my mother) my friend stuttered. (unrelatedly, my friend's father made a pass at my mother, my mother dutifully told my friend's mother, and the two families never communicated again; my mother was not believed.)

i myself am righthanded by the usual calculations: i use a pen or a fork with my right hand. however, i can only open bottles or deal cards with my left hand. i am ambidextrous for a passel of other activities. do i don't KNOW what i am, properly speaking, with regard to handedness, but i have reason to believe my verbal skills are no slouch.

Mom was a lefty

I used both hands equally until I went to school. That first child hating teacher was against using the left hand, and was proud that she could " break" a child to use their right instead. I got even with her, but that's another story. I've gone about my life using the more skilled hand for the project. For IV starts or foley caths, I use my left. Most other things I use both. Most would say I'm a Lefty forced to go right. I know I'm a both.

Interesting .
I am a lefty and a lot of my family is as well.

Taking into Consideration that most scientist are not left handed and may even be annoyed by Southpaws... what if they decide to get rid of Left Handed people? It will take a few Generations but once the gene identified... the gene can be removed or eliminated... Not the first time the attempt been done with less science... My grandmother was left handed... she noticed my mother was left handed and forced my mother to become righthanded tying up her left hand... I heard that story from other older people too how they were forced to use the right hand. Do Not Always Trust a Scientist to Be in Your Best Interest!!!

I have a left-handed nephew. Genius level IQ and a brilliant coder. Also a high-level Tae Kwon Do black belt. He's different, in the best possible way.

Stop boasting. I am almost jealous.

You all have some pretty cool traits. Having read all these responses, I regret to say that I'm right-handed.

Let me guess. Was the scientist a leftie

What about ambidextrous folks like myself. I write lefty, throw righty, play drums righty, use a fork with either, sew with either, and use most hand tools including a hammer with either.

I was born a lefty, but the powers that be, beat the Lord into me as a child. I found out that was born left handed, when I had a brain scan.

Left handed here, of course.

I'd be a little leery of making any connection to individuals, individual variation is pretty wide. That being said, fascinating that the rise of human language is almost certainly linked somehow to our very unusual species predilection for right handedness. I hadn't heard that before, thanks for posting.

This is very interesting. My youngest son is a left hand guy, and he is particularly good at verbal communication. He's a Fireman/Paramedic in Houston and has to be able to calm people down when they are stressed. He's very good at it. I sent the links to him. I'm sure he will show his big brother....LOL

I'm not left or right handed, I am cross-dominant or mixed-handed. There are some facts about handedness in the link I posted.

good to know ,interesting info

Took them long enough. I guess it shouldn't be surprising though, because it was linked to brain development rather than physical development. Now the next question to ask is why are there so many more right handed people, since it implies some sort of evolutionary advantage. What is it about having weaker connectivity between the right homologous language network and the default-mode network (DMN) and salience network that is so disadvantageous to left handedness?

Really.
