“在自然界里面任何植物和动物,只有一个自然选择所造成的目标——产生其相同者。狼的腿、毛、耳朵,这一切服务于一个目标——为了繁殖、为了增加狼的数目;蜉蝣生活一天,只是为了留下后代。”“把两个在一定程度上不同的性细胞(雌的和雄的)结合成一个细胞,把两个性细胞核结合成一个核,就造成生物体的异质性或对立面,以这种对立面为基础,就产生自体运动、自体发育、生活过程、新陈代谢(同化和异化)。由此可知,受精作用造成生活强度或生活动力。”——李科森 “Any plant or animal in nature has only one goal of natural selection - to produce the same .Wolf’s legs, hair, ears, all serve one purpose - in order to multiply, in order to increase the number of wolves;蜉 蝣 live a day, just to leave the offspring. ”“ To two to a certain extent different sex cells (male and female) into a cell, the two nuclei into a nuclear nucleus, resulting in biological Heterogeneity or opposites, on the basis of this opposition, produce autonomy, self-development, life processes, metabolism (assimilation and alienation), which shows that fertilization produces life intensity or life force. ” Sen
