Answer:
To increase our survival chance.
Explanation:
In order to survive in the harsh environment, Humans generally need to do 2 things : fulfill our basic needs and defend ourselves from external threats.
Both of them would be much easier if Humans are working together in a group.
For example, during hunter/gatherer eras, catching animals that can run faster than humans will be much easier if we have teammates to surround the prey rather than working alone.
On top that, being in a group also provide better protection from the attacks of wild animals or other humans. This is why human creatures get transformed into a social being.
According to Philip R.Shaver, there are three "behavioral systems" that play a role in romantic love: attachment, caregiving and sexual attraction.
You view love as an attachment when you are emotionally dependent on the other person for your happiness, safety and security, while love as caregiving refers to the great pleasure you receive from supporting, caring for and taking of a loved one.
Lastly, love as a sexual attraction is when you can't get the other person out of your mind and the thought of him or her excites you and turns you on.
If we will based the statement above from Shaver's model, we can say that the love being felt by John and Cynthia for each other transcends from attachment love to caregiving love.
