Abstract : selective mechanisms exist in organism and biosphere, which select the cells with less dna injuy and reproduces them. there are two models ; mechanisms 1 and mechanisms 2, represented respectively b bacteria and mechanolytes of human beings. cells with mechanisms 1 ( e. g. bacteria, generative cells, cancer cells ) can reproduce infinitely, while somatic cells can not. there are deep - going reasons behind the two categories of selective mechanisms. the canceration of the cells is a degenerating process from mechanisms 2 to mechanisms 1
摘要生物界存在一類篩選機制，它將dna損傷較小的細胞篩選出來，產生後代.主要有兩類模式機制1和機制2 ，分別以細菌和人的成纖維細胞為代表，那些具有篩選機制1的細胞（如:細菌、生殖細胞、
癌細胞）能無限傳代，而體細胞則不能.這兩類篩選機制背後有更深刻的原因，而細胞的
癌變正是從機制2退化為機制1的過程。
