摘要
目前关于人类性别在数量上大致均等的一般解释难以自圆其说。作者依据从进化论思想推导出的配偶供需量均等原则,不仅很好地解释了这一"大致均等"的现象,而且揭示了更深刻的"精确均等"内涵。它告诉人们:男性比女性在数量上稍多一点的根本原因,是因为男性的平均寿命比女性稍短一点。文章不仅定性而且定量地对此观点进行了说明。
For a long time,it is difficult to explain why the number of human sex is equal.The auther in this paper gives a reasonable explaining of 'approximate equality'and'exact equality'based on the principle of spouse supply provided by evolution theories.He also intends to reveal the following truth:the reason why the number of male is a little more than that of the female is that the male's average longevity is a little shorter than the female's.This paper has given qualitative and rationing analysis on this point of view.
