The Evolution of Love

Evolution of love
Love can transform us in many ways for the better. Learn why and how you should tap into this powerful emotion in your life and how you can spread it.

Love might be the best, yet most mysterious and confusing feeling that humans experience. Just like any aspect of human behavior, love is controlled by biology and biochemistry.

The Transformation of Love

Our body has many systems in place, from chemical to psychological, which ensure that we fall in love. But why does love exist in the first place? How did it evolve over time?

We often think that intelligence is the nemesis of love, you either think with your heart or your mind. But as a matter of fact, intelligence and love share many elements when it comes to evolution.

Love becomes smarter

As our ancestors became smarter, their brains grew bigger. But without the bond of love, humans would not have propagated across continents think about it, human babies required a lot of love, attention, and affection and had a lot to learn before they could become independent.

Hence, they relied on their parents to nurture them for a longer time. Love did not come out of the blue. It had an evolutionary purpose. First of all, love made sure our ancestors stayed committed to each other, which increased their chances of raising children and keeping them alive and consequently led to the preservation of their gene pool, and at the same time spreading it across continents.

One way love did this, was by suppressing the desire to find other mates. Some studies show that people in committed relationships find others less attractive than they would if they were single. Love also tricks the chemistry of our brains.

Love Hormone

When we experience love, our brain releases Dopamine a hormone and neurotransmitter that gives us pleasure. As love becomes more intense, the brain rewards us with more dopamine. Evolution has also borrowed some mechanisms from the mother-child love dynamics and used them in creating romantic love. As an example, the hormone is released when a mother hugs her child. Similarly, oxytocin leads to romantic bonding between humans, which is why it is sometimes referred to as the “love hormone“.

What’s even more interesting, is that ht more oxytocin receptors the brain have, the stronger, supposedly, the person’s marriage bond is and the longer relationship can last. These rewards and happiness-including hormones and neurotransmitters, ultimately promote the person’s brain to stay devoted to their partner who, in turn, helps gather resources and provides protection for the offspring.

Romantic love also helped increase the motivation of our ancestors in the challenging task of nurturing children until they became independent. For instance, human males are the only primates that support and nurture their children along with their mothers.

Enhanced Cognitive Skills

Evolutionary speaking, collaboration means higher chances of survival. That’s what love gave us. Love seems to have played an enormous role in enhancing cognitive skills. As humans fell in love with each other and formed long-term relationships, they ran into many relationship problems, just like modern-day couples.

Along with the relationships they formed with their partners, our ancestors also had to learn how to deal with other members of the clan like mothers-in-law, partners’ sisters, brothers, and many more relatives. These complicated relationships led to humans building a high level of cooperative skills and social intelligence, which helped our brains grow bigger.

The increase in brain size than allowed us to develop language and advanced consciousness. As such, with just a little bit of love, humans made the final transition from a primitive simple brain to a complex one. However, nowadays we live in a different world.

While raising kids remains a challenging task, it has become easier than before. There is no more need to hunt for your food, walk miles to gather it or protect the cave from tigers. Does this mean that we don’t need love anymore? Can our brains slowly devolve back to lovelessness?

To our relief, that is unlikely to happen. Love is here to stay, it still plays a crucial role in interhuman relationships. Even the most primitive parts of our brains, like the tegmental area, a reward hub, and the amygdala, the fear center, are wired to recognize and nurture love. So rest assured, even though thousands of years have passed, we still have a strong desire to love and be loved. In the end, that is what keeps us humane.
