how marriage evolved
I am going to start it saying, we are also an organism like all other organism on planet earth. And as all other organism is born inherited with “Reproductive qualities” for continuity of their species, we are also inherited with same quality.
But when we compare us with other organism, we find that our biology is different than other organism. Suppose if I talk about Cow, it give birth to a child in the morning and till afternoon it stand on its own feet, for few months it will drink mother’s milk and then start eating grasses, and its almost the same with most of other organism, that their children mature fast to become adults.
