What is the logic behind giving father's name as surname??

Well in traditional societies, men are often valued much higher than women. Women are seen as objects, they are objectified. This is why, a girl belongs to his father when he is young, and when the girls grows up to become a woman, she is then passed on to her husband. This is why in some societies people pay a bride price, or in some rural areas, husbands 'pay' for the wife by giving her family a cow or some other livestock. Thus when women are married, their first name/surname followed that of their father's. The children that women give birth to are naturally considered as the father's as well. This is why children have their surname taken after their father, and not their mother. This may sound illogical and even outright wrong to some people, especially women, but this is the way it works from the olden times. It is also the same reason why people assume a "he" instead of a "she" when no specific gender is specified.

It's been a heredity. I don't know where is come from. But it like to keep the descent still exist. I also get the surname from my father. They said that it show your ancestor and where I came from. So if I meet other people that I don't know who is he/she but has the same surname with me. My father told me that I and the strange people is has a related and from the same ancestral. That's what I know. Keep post Happy myLotting...
