Some of us are capable of falling in love at first sight (and, what to hide, do it all the time), while others do not. It is as pointless to argue with this fact as it is with the fact that the earth is round. But instead of explaining our ability to fall in love with a person whom we saw in a subway car or met in a queue at a supermarket with personality traits, scientists, as they should be, chose a more complicated experimental path.
We note right away that the study in question was carried out on fruit flies. Researchers at Cornell University's research laboratory have found that females of these insects are biologically oriented towards identifying males with whom they are genetically compatible, and, as observations have shown, it is when mating with individuals selected "at first glance" that females produce more eggs.
Despite the fact that experiments with human participation have not yet been carried out, scientists are sure that we - at least women - have a similar biological mechanism.
Why does a person even call the feeling that arises when looking at an extremely handsome stranger love? Andrew Clark, lead author of the study, suggests that not only vision is at work here, but also smell, tone of voice and, quite possibly, some other non-obvious factors that are actually more important than they seem.
Scientists say: how long does love last
A number of researchers are of the opinion that the genetic component dominates in one-time love. They say that when we meet a person with an ideal set of genes (that is, one that guarantees high-quality offspring), a certain biological reaction occurs. We usually call this reaction love at first sight.
You might say that love is a complex feeling that cannot be explained by biology or physiology alone. And we will agree with you, because the scale of the phenomenon requires similarly large-scale experiments.
