>>770562You as an organism are not going to particularly benefit from passing on your genes. In fact, evolution more or less subordinates your existence to your genes: your body, mind, whatever is being exploited by your genes as vehicle to reproduce themselves. On the other hand, by taking responsibility for and investing into the society you live in, regardless of blood relations, you are going to benefit yourself by making the world you live in a better place. You will also form bonds with specific people, regardless of genetic relation, that provide benefits both ways. There is no real rational reason to favor your own genes on the basis that they are your genes. It's just instinct that your genes chain you with.
