Previous studies looked for the existence of a genetic or neurological basis of love, and this focused on the relationship between love and the reproductive role of man in ancient times and revealed that love played an essential role in human evolution.
The scientists studied the Tanzanian tribe Hadza, whose lifestyle has not changed for thousands of years and can give insight into the meaning of love in our prehistoric ancestors. Members of the tribe of Hadz do not use contraception and love measures with the number of children. The more children, the love among partners is stronger.
"All three of Sternberg's love components are important in the context of human reproduction. Our study casts a new light on the role of love in the evolution of the human race, especially in traditional hunting-gathering communities, in which individuals, and not their parents, were responsible for choosing a partner with whom the family will be based, "the authors of the study, Journal "Frontiers in Psychology".
A new study has shown that love is associated with the reproductive success of humans since ancient times and to the extent that it has made it an evolutionary factor.
"It could be said that passion and commitment are key factors that increase the likelihood of survival of the species, and for this reason love was one of the evolutionary factors," the authors explain. Of course, the concept of love evolved and today it is completely independent of the reproductive success of the couple.
Scientists conclude that people, even in the very beginnings of the human race, fell in love and loved to have more children, to extend the species and to prevent the infanticide that men were prone to.
