Who makes children

Since the school day, we know from the lessons of biology where the children come from.
But I drew attention to the moment that the contribution of a man and a woman is not dissimilar.
The process consists of conception, bearing, birth, cultivation and training.
Let's take a closer look at these stages.
Conception. In fact, a woman has everything that is necessary for conception. This is the egg and the place where it can happen. The egg is the future organism. From it development will begin. It has the nutrients necessary for the first time to multiply the cells. The woman owns the egg cell. But there is one but. It's a sperm. Without which the process of beginning division of the coot will not begin. The sperm can not live by itself-this is a set of genes, our DNA. The egg is huge, it is the largest cell of the human body. Spermatozoon can not be seen without a microscope.
Why did you need an additional set of genes. Everything is very simple. To survive. With the constant folding of different genes, it is almost impossible to obtain a repetition, and consequently the protection and survival of the biological species is enhanced.
Conclusion: a man needs to be conceived. A woman has an egg and a way to conceive. The score is 1: 1.
After conception, the process of growth begins. If fertilization was successful, the cell begins to multiply. From one two, from two four and so on. The process of growth occurs in the womb of a woman. Muzhchina while resting, he is not with it. The score is 2: 1 in favor of the woman.
The next stage is childbirth. And again everything is done by a woman. Of course, a man can support the camera to shoot births, or say a few words, but this has nothing to do with the essence of the process. The score is 3: 1 in favor of the woman.
Here the birth has passed and the process of human development has begun. All that is needed now is food. Feeds the young woman of course. And not only feeds, it grows. She takes care of him. The score is 4: 1 in favor of the woman.
And then when the baby grows up a little, the man begins to pay attention to him, do something with him, train or train. Of course, a woman does not stand aside, but I'm inclined to think that a man teaches more. The account in this case remains unchanged 4: 1 in favor of the woman.
What are the conclusions. In fact, females, could have multiplied, if not for fear of perishing from an accidental virus. And that man, participates only in conception. How can he understand what is birth or pregnancy, or how to feed the baby with breast milk. Of course, a man needs help, but everything depends on the living conditions of his life. Is not a fact.
