Résumé
"The need to elaborate a new evolutionary theory is discussed. Several arguments are given to justify a new theory, mainly based on present interpretation of different phenomena such as endosymbiosis, reticulate evolution, the modern synthesis of embryonic development and evolution (evo-devo), phenotypic plasticity, epigenesis, evolvability, and the several evolutionary mechanisms: natural selection, gene flow, genetic drift, fusion of genomes and gene fragments, epigenetic mechanisms such as methylation of DNA, tool kits, regulatory cis-elements, hybridization and polyploidy. As well as mutations, other sources of genetic variation must also be included."
