Rewrite: How the biology influence history？(part one) History needs to be understood by the human, rather it just a mass of meaningless material flow in the space and time axis. The history we pass is only a fragment of biology. Even our society is complex, each human in this network still cannot escape the law of biology. Most of our needs based on our body, such as eat, breed, finding a safe place to live. It's no different than a normal animal. I do not deny that we have a special place such as the spirit, but on a large scale, we can see In the garden of all the species, the human is just a flower, which is unique. Therefore, the law of biology is a fundamental lesson of history. We need to face the challenge of evolution, the struggle of existence, the natural choices of who survived. The first biology lesson of history is that life is competition. Individuals kill each other for food. Small group protect his member and against another group. The ultimate form of competition is war, It's cruel, but promotes cooperation and request the quality of an individual. The second biology lesson of history is that life is selection. We are all born unfree and unequal, subject to our heredity and group. But we need to face the same test from nature. Our civilization foster this inequality. The individual who has great strength or intelligence is valuable to the group, it gives unequal a place to grow. We can see that some people want to equal, especially those who below the average economy ability. But nature smiles at all of the utopias in our hope. He talked to the philosophy that you can try to achieve approximate equality of legal justice and educational opportunity.
