title: [Hypotheses on the evolution of DNA and organic beings].
abstract: An hypothesis is presented in which all the genes of living organisms are proposed to arise from the juxtaposition of the genes from different elementary organisms. There would be no creation of genes afterwards, only modification by mutations. The ulterior transformation of organisms would be due to evolution of chromosomes towards the most stable state, by crossing over during meioses.
