Trends that produced today's biodiversity are: from simple life forms to ever more complex biological organization; from few ecological functions to many; from simple ecosystems to ever more complex, three-dimensional ones; from few senses to more complex senses; from a highly toxic primal ecosphere to a progressively less toxic one that became ever more suitable and conducive to the evolution of diverse life forms from pre-existing biodiversity. 1, record 1, English, - three%2Ddimensional%20ecosystem
Ces tendances sont les suivantes : des êtres vivants simples aux ensembles biologiques plus complexes; des fonctions écologiques peu nombreuses aux fonctions écologiques multiples; des écosystèmes simples aux écosystèmes tridimensionnels toujours plus complexes; des sens peu nombreux aux sens plus complexes; d'une écosphère primitive très toxique à une écosphère progressivement moins toxique, toujours plus propice à l'évolution, à partir d'une biodiversité pré-existante d'organismes encore plus diversifiés. 1, record 1, French, - %C3%A9cosyst%C3%A8me%20tridimensionnel
