Les Vert\u00e9br\u00e9s sont des Chord\u00e9s \u00e9volu\u00e9s, \u00e0 savoir des M\u00e9tazoaires Deut\u00e9rostomiens \u00e0 chorde dorsale au moins primitivement. Ce sont des animaux qui se caract\u00e9risent par la pr\u00e9sence d’une colonne vert\u00e9brale. Vert\u00e8bres, cr\u00e2ne, axes de sym\u00e9tries sont autant de points communs \u00e0 tous les Vert\u00e9br\u00e9s. On en d\u00e9gage l’existence d’un anc\u00eatre commun qui a d\u00fb vivre il y a un peu plus de 500 Ma. Sauf quelques cas, tous les Vert\u00e9br\u00e9s actuels ont un squelette osseux. Cet ensemble a une origine commune. On d\u00e9couvre que les Oiseaux et les Crocodiles ont seuls, un g\u00e9sier. Ce point commun leur donne une origine commune \u00e0 rechercher au sein des Dinosaures.<\/p>\n\n\n
