VIDEO: OAMENII DE STIINTA AU DESCOPERIT GENA INFIDELITATII SI A OBSEDATILOR SEXUALI DE AMBELE SEXE .The love-cheat gene: One in four born to be unfaithful, claim scientists

Supozitia glumeata, conform careia unii oameni au infidelitatea in sange, si-a gasit, in sfarsit, confirmarea stiintifica. Dupa ani si ani de cautari, o echipa de cercetatori americani a descoperti gena care ne arunca in promiscuitate,indemnandu-ne sa ne cautam neincetat alti si alti parteneri sexuali de ocazie.

Pe baza primelor cercetari, gena buclucasa (botezata, in gluma, gena sobolanului obsedat) este responsabila de comportamentul deviant al obsedatilor sexuali de ambele sexe. Cand un barbat sau o femeie posesor / posesoare al genei in cauza, vede un potential partener sexual, acesta / aceasta „traieste” o reactie chimica extrem de puternica, comparabila doar cu senzatiile unui parior inveterat care simte mirosul castigului, sau cu trairile incontrolabile ale unui alcoolic care isi savureaza bautura preferata.

Cercetatorii Universitatii de Stat din New York au studiat un lot de 180 barbati si femei, testandu-i, initial, in cautarea genei infidelitatii, denumita stiintific gena DRD4. Cei la care a fost identificata „gena dezmatului” s-au dovedit a fi cu mult mai nerabdatori in a-si insela partenerul(a) actual, in favoarea unei experiente sexuale cu necunoscuti(te).

Gena DRD4, odata activata de noua experienta sexuala, elibereaza o mare cantitate de dopamina in creier, oferind persoanei senzatii puternice de placere. Noua descoperire a venit la scurt timp dupa ce oamenii de stiinta americani au anuntat, in decursul lunii trecute, ca proaspat identificata gena DRD4 poate afecta chiar viata politica, deoarece oamenii care o poseda sunt intotdeuna inclinati in a avea si expune pozitii si opinii liberale.

The love-cheat gene: One in four born to be unfaithful, claim scientists

It might seem like the perfect get-out clause for those with a ­roving eye: some people just aren’t built to be faithful.

Scientists have found a gene that raises the odds of ­cheating on a partner.

They say that when a man or woman with the ‘love rat gene’ has an affair, they receive the same chemical rush as a gambler whose luck has changed or an cheating on a partner

The tendency to cheat could be down to a variant in a person’s genes, a new study has found (picture posed by model)

Researchers quizzed 180 young men and women about their attitude towards relationships and tested them for a gene called DRD4, which affects levels of the brain chemical dopamine.

The one quarter or so with the ‘love rat’ version of the gene were more than twice as likely to be unfaithful. And when they did cheat, they had more one-night stands, the journal PLoS ONE reports.

Researcher Justin Garcia said: ‘What we found was that individuals with a certain variant of the DRD4 gene were more likely to have a history of uncommitted sex, including one-night stands and acts of infidelity.

‘The motivation seems to stem from a system of pleasure and reward, which is where the release of dopamine comes in.

‘In cases of uncommitted sex, the risks are high, the rewards substantial and the motivation variable – all elements that ensure a dopamine “rush”.’

He added that his results suggest it is possible to feel committed to a partner, but still feel the need to cheat on them.

But those with a wandering eye cannot wholly blame their genes.

Mr Garcia, of the State University of New York, said: ‘The study doesn’t let transgressors off the hook. Not everyone with this ­genotype (genetic make-up) will have one-night stands or commit infidelity.’

Last month, scientists found that the same strain of the DRD4 gene can also make people have more liberal views.

Because the genetic variant drives people to seek out ‘novelty’, it can also make people more likely to seek out less conventional political views, the U.S. study found.

Those with the gene supposedly seek out other people’s points of view and are influenced by them far more than those without the gene.

In the U.S. this mean that people with the gene were more likely to have a liberal political viewpoint.
