Why Love

One often wonders why life evolved on earth, why certain compounds in the planet came together and formed a system that would grow, divide and create its own copies and evolve from simple one cell living being to complex multicellular living organisms. 

As organisms grew more and more complex, they developed their neurons into complex neural networks which ultimately evolved into their brains. The brain controlled the various functions of the body both internal and external. The brain connected to various parts of the body through a vast network of neurons. 

This neurons would communicate the information in form of electric impulses to the brain. The brain would send information to appropriate part of the body to take the correct action. If the skin organism touches fire, the neurons attached to the part of the skin would immediately send the signals to the brain , the instinctive intelligence that evolved in the organisms over millions of years would direct them move that portion of body away from the fire. 

Various sense organs developed like the eyes, nose, ears, tongue etc. This organs sent information to the brain about the various happenings around the organism, so that the organism can react to the feedback and take appropriate action for it to survive. 

There is one more evolutionary instinct that developed in almost all living beings in varying degrees. We call that Love. This is more apparent in case of mammals, specially humans. 

Man and woman fall in love and started staying together. Which later evolved into marriage as humans got more civilized. The civilized humans controlled their basic sexual instinct and had sex only with their married partners. Of course in many cases deviations were there when the man or woman had sex with other partners, however 99.9% of the sexual intercourses in humans happened between married partners. The number may vary with country, culture and time period but the proportion of married sex is always much higher.

Since most sexual intercourses happened between married partners, the probability of the female partner getting pregnant with the baby of her married male partner is close to 100%. It is commonly observed that women have more attraction towards love and relationships, they tend to have sex with only those men who would stay with them for a long period of time. This can be easily understood, first of all the man has only one function, release the seamen in the vagina of the female sex partner. 

That is exactly why sexual intercourse evolved in living beings. The seamen contains the sperms that fuses with the egg of the female. Once that happens a baby is conceived in the womb of the female organism. The cells keep dividing fast and slowly different organs are formed. Then after a certain period of time the baby is good enough to come out of womb of the mother and live and grow in the world. 

When a woman gets pregnant she needs someone too look after her during pregnancy, this is where the role of the male partner comes into play, specially during the later and final months of pregnancy. Both parents have a major role in bringing up the baby. The mother's role is very vital in bringing up the baby, specially in case of humans and other mammals. The mammals have mammary glands, the mammary glands produces milk, which is the main food of the baby for the first few month when it needs the utmost care. 

While in case of animals the role of father is limited. In case of civilized humans the role of father is also very important. 

In human beings there is a tendency to be attracted towards men and women other than one's married partner. This happens more in case of men. The reason for this can be understood from the fact that humans have actually evolved for animals. Our ancestors were animals.

Men can potentially be more adulterous than women because evolutionarily speaking a man can impregnate more than one woman in one year, the numbers can potentially go into hundreds. However a woman can become pregnant only once a year. 

In humans and other mammals there exists a bond of love between the mother and newborn. It is this emotion of love that makes the mother take care of the baby. However love is not limited to  mother and child , there is love between father and child, granny and grandsons and granddaughters. 

So it is clear that emotions and feeling have evolved with evolution of life on earth and the main reason for this is the smooth continuity and evolution of living beings. Take example of birds, how passionately they build their nests, take care of their eggs, feed and look after their young ones. The same is true in case of majority of life forms on earth. 

All of us have seen and experience that when we do something we love to, not only we are happy, but at the same time we do the work very efficiently as well. Its people's love for beauty that makes them build beautiful structures, roads, buildings, cities etc. In case of a soldier its his love for the nation( patriotism) that makes him risk his life to protect it.

Without love life would have existed, but it won't have evolved to the levels of humans or mammals . Hence in all spiritual and philosophical books love has been given great importance and even scientifically speaking it is a very vital emotion of life.
