Does love at first sight actually happen? Well, scientists say that the answer to this ever-existing query lies in geneticists.
In a study on fruit flies, American and Australian researchers have discovered that some males and females are more compatible than others at the genetic level.
In their opinion, this compatibility plays an important role in mate selection, mating outcomes, and future reproductive behaviours.
The researchers say that the experiments conducted by them have shown that before mating, females experience something called "genetic priming", which makes them more likely to mate with certain males over others.
"Our research helps to shed light on the complex biochemistry involved in mate selection and reproduction," said Mariana Wolfner, Professor of Developmental Biology at Cornell University and the senior scientist involved in the study.
She added: "These findings may lead to ways to curb unwanted insect populations by activating or deactivating genes that play a role in female mating decisions."
For the study, scientists mated two different strains of fruit fly females to males either from their own strain or to males from the other strain.
They noted the males with which females of each strain tended to mate, and then examined whether the females showed differences in behaviour soon after mating and in reproduction-related activities, such as how many offspring were produced and how many sperm were stored.
They also analysed females' RNA to compare the genes expressed in females mated to males of different strains.
It was found that despite observed differences in mating behaviours and reproduction activities in females mated to different strains of males, there were only negligible mating-dependent differences in gene expression between the groups.
Based on their observations, the researchers came to the conclusion that genetic changes involved in mate choice and reproduction existed before mating began.
The study has been published in the latest issue of the journal Genetics.
Nice article on fruit flies. There is attraction at first sight. But whether that attraction is "love" still needs to be verified. That is the reason why among human beings there is a period of wherein the interested parties get to know each other.

Nope. If it's based on sight, it's attraction.

OK, I'll bite.

Genetic compatibility as reproductive motivation is not the equivalent of complex emotional ties, which is how most people would define love.

By that logic, a woman who goes to the Sperm Bank for artificial insemenation, and chooses sperm based on genetic characteristics, is also proof of "love at first sight" when she uses a sample that is more genetically suited to her. Interesting.
Is this really an important enough topic for geneticists to be wasting funding and research on? I wonder what would happen if all scientists stopped doing this crap and focused more on curing cancer and AIDS or something in that direction. | subirbasak wrote: |

That would depend greatly on how you define love. | ocalhoun wrote: |

True. I fell in love at first sight with a boat one time.I believe in true love, but no one can recognize it, because no one knows how to love. Every one has an idea of love, and its just the wrong idea. Love is not forgiving if they cheat on you. Love is never having to cheat because you really care about your significant other. Love is not one person sacrificing their life to make the relation ship work. Love is two lives making a compromise to make one solid union. Any way love at first site is impossible. You must really know a person to love them. True all relationships start with an attraction, and love at first site would really be just two really horny people that are really attracted to each other, but not love.
yes love at first sight can happen in life.infact i was in love at first sight. whn i was in 10th std in my school life.thats why i think it can happen...but not for everyone.
I have to say that I feel that love at first sight is possible. I personally have had it happen to me. It was not from what she looked like but just what I felt the first time seeing her. I knew at the moment that I wanted to be with her and I wanted to care for her for the rest of my life.
Don't forget smell. There is evidence that part of attraction in many species can be related to MHC genes (they are a component of your immune system). There appears to be a link between women being more attracted to men with different MHC genes than their own, thereby improving their offspring's immune system.
I do beleave love can happen in first sight.
I've heard about it, but that has never really happened to me ... so far anyway. My experiences have usually evolved out of friendships. In the end the friendships were the better part of those relationships!

True.
Although love at first time happened to me once or twice...
So I do believe in it, but I totally agree with deanhills.i believe on it that love happens at first sight....
For me, I agree that there's an attraction but love isn't the correct term. In my opinion, love is something that you feel for someone you want to protect. Someone who understands who you are and accepts whatever you have. But putting it "at first sight" i can't prove it for myself. There can be love developing "in time".
Love at first sight... this word "love" is soooo relative!
It happened for me ones but now, after 10 years, I believe that the feeling weren't love but attraction (as Solon_Poledourus said).
You see a girl and you want to dance with her all night, to talk ages, to kiss her and in the end (not to far this end) to make love to her. Is this love or attraction?
Now I call it attraction... 
love at first sight? for me, i think you'll like the person first, then fall for love later xd thats just me
it depends on the persons personality
and likes ^^

love is a phenomenon we relate it with heart but its nothing to do with heart its the brain who makes love, every one admire beauty its common to every one so the love at first sight came into playDoes love at first sight actually happen? I think it's hard to say if it's love. You see,what's love based on? at first sight,you just get little information about a person,and more about his or her appearance,to the character no one can know well at the first sight. And now if you believe love is based on the appearance, may be love will happen, but if you don't believe that, then what about love?
I think love at first sight can happen. To some, it may seem irrational, but to me, it's definitely possible.
