Before I explain in details, we need to understand whether we are altruist by social education or as a result of evolutionary inheritance? Is altruism embedded in our genetics?
The word "altruism" (derived from French autre "other," in its turn derived from Latin alter "other") was coined by Auguste Comte, the French founder of positivism, in order to describe the ethical doctrine he supported. He believed that individuals had a moral obligation to serve the interest of others or the "greater good" of humanity. Comte says, in his Catechisme Positiviste,
social point of view cannot tolerate the notion of rights, for such notion rests on individualism. We are born under a load of obligations of every kind, to our predecessors, to our successors, to our contemporaries. After our birth these obligations increase or accumulate, for it is some time before we can return any service…. This ["to live for others"], the definitive formula of human morality, gives a direct sanction exclusively to our instincts of benevolence, the common source of happiness and duty. [Man must serve] Humanity, who we are entirely.
Although in all the religions, altruism is the foundation of their very existence, in biology definition is tricky and at a time uprightly rude. My action will be under the definition of biological altruism if it reduces my reproductive fitness while increasing the same for the benefactors [1].
For example during the freedom struggle of India, all the freedom fighters risked their life as well as survival of their family so that fellow Indians can live in freedom and prosperity. The same phenomena is also observed throughout the biological kingdom-birds guard the eggs of the other birds risking their lives. Question that scientists always tried to answer- why the species, or we the biological beings tend to sacrifice our own reproductive fitness when from Darwinism it appears, we are nothing but a genetic survival machine? How would you explain this anomaly [2][3][4]?
Biologists came up with two possible explanations. Darwin tried to explain this as group selection-that is survival of a genetic group is more important than individual genetic mark-ups. But Richard Dawkins explained such group genetic explanation has problem with " subversion from within" [2].
Imagine that in a group of birds with altruistic genes, one mutant bird with a selfish gene is born. This selfish bird will be a "free rider" because it will have an advantage in reproductive fitness in virtue of the altruism of the other birds. Consequently, its selfish gene is more likely to be reproduced, and, over time, one would expect a selfish mutant gene to dominate over the altruistic gene. A counter to this model would be the consideration that if groups are benefited by altruism within the group, then a more altruistic group may well hold a selective advantage over a second group weakened by the individual with the selfish gene[2][3].
Therefore the second possibility is with kin selection and reciprocal altruism. This means, if I be altruist to your cause, you will be to mine as well- a simple game of favor exchange. Gandhism is based on reciprocal altruism. That is, if we be kind enough to our opponent and let them see through clearly that we are their friends and not foes and thus by doing so, if our opponents realize that our altruist behavior is to his benefit where as his oppressive nature is even against his own reproductive fitness, there is always a high possibility our enemy will turn altruist towards us as well.

nice article.
it's in our genes to be good, and it's because, it's good for the genes to make it's carrier do good.
i consider darwin and dawkins to evolutionary theroy as newton and einstein is to gravity.
dawkins replaced genes as basic units of evolution. an individual is just carrying out the orders of his genes. previously it was thought it was the group of genes, that consists an individual, that evolve, as a group. but dawkins, in his master stroke showed, individual genes evolve seperately, even though they may cooperate temporarily (not just for the life time of an individual, but for generations, till it's in association with a particular gene). sometimes genes in two seperate individuals of different species cooperate, like our genes and that of E Coli in our gut. the mitochondria in our each cell was actually once a fee living organism, which at some remote time, started cooperating with genes of eucaryotic cell, by getting engulfed by it, and doing work for it. today, we talk of mitochondrial genes as our genes.
our genes take interest in protecting its host (us) only because, it is in their interest. if a gene could distribute it in 4 other individual, and then, kill it's host, which stands in the way of those 4 individuals thriving, it'll certainly do that, because it assures its survival in 4 different sets, rather than one. (that's why we die!) so, it's not the individuals' interest, but the interest of the genes, that's always taken care of.
in this struggle for existance, it's in the genes' interest, that it takes care of not just the body that it's living in, but also other individuals, that's carrying the copies of it. our immediate relatives are likely to carry my genes (or they may be my spouse's.) in a case of emergenecy, it may be in my genes' interest, that i sacrifice, and let my children live. that's why we love our relatives and immediate people (there's no way to recognise one's relative, but accept the immediate individuals as relatives)
so, genes evolved love, cooperation, altruism, in order to safe guard their own interests, but it translates to great moral values to us humans. (or our genes make us believe that these values are great morals)
but genes are any way, in fierce competetion with one another, and it's in their interest, that other genes, even though, they may be in the same individual, dont survive as much as they do, and that they can outnumber the others. so, they make their carriers fight, hate, commit crime etc, against individuals, who are less likely to carry their own copies. (a pakistani is less likely to carry a copy of a gene in my body than a random indian). so, genes which make us behave altruistically, also, imbibe ethnophobia in us.
but our genes evolved their characteristics, in the infancy of human race, when each individual was affected by a few other individual in his immediate vicinity. today, we live in a different world, where we are globally connected to all the individuals in the world. our basic instincts that our genes dictated to us, the instinct to kill, instinct to hate, wont be survivally beneficial, in this changed scenario.
so, our genes' instructions to us, the instincts of ethnophobia, may not be the best in our interest.
we can study the outcomes of human interactions, in different social situation, by various means. one of them is game theory. different versions of game theories have been devised, which simulate different kinds of interactions between individuals, and surprisingly they show, that cooperation still benefit us! nice guys indeed do finish first in the world. watch this wonderful video by richard dawkins:
