Why we have a love?

Answer 1

Love is affection, wanting to include the target to ones pack.

Because the early primates were small and vulnerable, they sought safety and comfort from other individuals. Becoming gregarious meant one had to develop means how to maintain the pack close and together.

Because the survival had already taught the primates to take care of their young, to extend that care and affection to other members of the pact was an easy step.

Love in it´s rawest state, is to 'take care of others, so they will take care of you'.

Later on when humans evolved and lost their mating seasons, it became necessary to form good relations between the male and female, so the male would be there ready when she was fertile. Without outerior signs (like red buttocks) it became impossible to know when she was in season, especially when the wolf came into human's life and cause the humans to concentrate on visual things, when the wolf concentrated on smells. Humans lost their keen sence of smell because of evolution. The only valid method left, was to maintain good relations between man and woman.

Also, because the human fetus requires quite a long time to carry full-term, and is not able to take care of itself for years, humans kept developing this care-taking of relations into a higher level. Somewhere in the evolution the primates were awarded taking care of each other, not only with survival, but also with oxytosin.

This hormone is released when one's skin is touched and it affects on brains causing eurofia. This is the love hormone. This is also the mother-young hormone, which is necessary to work, so the youngs would get the care they needed to survive, so in that sense we already had all the required organs for love, extended only to include other individuals than just your young.

And during the evolution those humans were selected to survive, who had the best production of oxytosine and who took care of other causing them a flood of oxytosine and therefore they got more taking care in return, and so were protected by others.

So in natural selection, the population preferred love and kindness. So love and kindness saturated.

In short: simple survival-strategy was evolved into pleasure.

Also do not confuse 'falling in love' with love and affection. Falling in love is yet a different chemical process, which is caused by feromones and can only last max 2 years. Which is not enough to take care a human young.
