In der Regel haben Landwirbeltiere fünf Finger oder Zehen pro Hand oder Fuß. Viele Tiergruppen haben im Laufe der Evolution diesen Bauplan allerdings abgewandelt. So haben etwa Paarhufer nur zwei oder vier Zehen. Ähnlich sind im Flügel der Vögel nur drei knochige Finger vorhanden. Die Anlage eines vierten Fingers auf der Handaußenseite (posterior) lässt sich bei Vögeln jedoch embryonal belegen. Dadurch stellt sich die Frage, um welche Finger es sich nun tatsächlich handelt: Daumen, Zeige- und Mittelfinger (I, II, III) oder Zeige-, Mittel- und Ringfinger (II, III, IV). Theoretische Biologen der Universität Wien haben dies geklärt und publizieren dazu aktuell dc Ufobctc bp Zaxsjfwlmwep Ckqekqs.
