Keywords: Phylogenetic tree-fr.svg A phylogenetic tree of living things based on RNA data and proposed by Carl Woese showing the separation of bacteria archaea and eukaryotes Trees constructed with other genes are generally similar although they may place some early-branching groups very differently thanks to long branch attraction The exact relationships of the three domains are still being debated as is the position of the root of the tree It has also been suggested that due to lateral gene transfer a tree may not be the best representation of the genetic relationships of all organisms For instance some genetic evidence suggests that eukaryotes evolved from the union of some bacteria and archaea one becoming an organelle and the other the main cell Arbre phylogénétique hypothétique de tous les organismes vivants L'arbre est basé sur des séquences de l'ARNr 16S à l'origine proposé par Carl Woese il montre l'histoire évolutive des trois domaines du vivant bactéries archaea et eucaryotes http //nai arc nasa gov/library/images/news_articles/big_274_3 jpg NASA Astrobiology Institute found in http //nai arc nasa gov/news_stories/news_detail cfm ID 274 an article 2006-09 This vector version Eric Gaba Sting - fr Sting Public domain Other versions/Phylogenetic tree Atelier graphique Cet arbre est faux on ne sait pas qui est apparu en premier des Eubactéries Archées ou Eucaryotes L'ancêtre commun aux trois groupes du vivant se nomme LUCA et il est encore inconnu Ce qui est sûr c'est qu'il n'existe pas d'organisme extra groupe et donc que l'arbre ne peut pas être implanté Il faut représenter l'arbre du vivant sous la forme d'un arbuste n'ayant pas de racine fr French Wikipedia Sting Phylogenetic tree of life French SVG diagrams in French Last universal ancestor
