Deux principes utilisés en anatomie comparée:
Principe d’homologie:
• Deux organes homologues ont la même
origine et la fonction peut être identique ou
différente
Ex: Marteau / Os articulaire
(même origine: cartilage de Meckel)
Principe d’Analogie:
• Deux organes analogues ont la même
fonction mais l’origine est différente
Ex: l’aile du papillon/ l’aile des Oiseaux
