人類是一種天生就具有公正感的物種。本文旨在用演化的視角來探討人類公正感的產生，模擬我們的祖先由原始猿類演化至原始人類的時期。在這期間，在自然演化的壓力下，具有一定程度公正感的個體更易繁衍後代，因此經過2000多萬年的演化，公正感的DNA片段具備了博弈論上的收斂性，最終我們祖先都具有這種DNA片段。但自從進入了文明時代，隨著人類科技的不斷發展，人類的自然演化壓力已越來越不同於我們的祖先，因此這種收斂性或許會逐漸消失，最終該DNA片段會成為被放棄的生物學性狀。

Human beings are born with a sense of fairness. This article aims to discuss how such sense is produced with evolutionary game theory, and simulate the evolution of our ancestors from primitive ape to hominid period. During this period, the pressure of natural evolution makes the individuals with fairness sense to be easier to reproduction. So after more than 2,000 years of evolution, the DNA fragment of fairness has the convergence of evolutionary game theory. Ultimately, all of our ancestors have this DNA fragment. But since entering the era of civilization, the pressure of natural evolution has been more and more different our ancestors with the development of technology. So this convergence may gradually disappear, and ultimately this DNA fragment will become useless biological character.
