Let us leave the geneticists to answer the question, which is at the end of humanity from the very dawn of its existence to the present day: is there really love in the world at first sight? According to the study published in April 2009 by the Genetics magazine, a team of scientists from the USA and Australia, opened that at the genetic level some male and female individuals are more compatible than others, and that this compatibility plays an important role in choosing a couple, the results of the choice and the future reproductive behavior. Why are we talking about “individuals”? Well, as always, they began to study with fruit flies … So the females of these very flies before mating are “supplied with genetic information”, which inclines their preferences towards certain males. Scientists want to shed light on the biochemistry of love, friendship and sexual relations! How quickly they will go from a fly to a person – another mystery. In the meantime, the editor -in -chief of the magazine Mark Johnson commented on the study as follows: “From this it is clear that females really care about the nature of their chosen one, but they may not have the control over the choice of how they would like to think”. Hmm … Isn’t it a stone in our garden? – Flies, it seems, do not think.
