Der Unterschied zwischen Mensch und Tier: Ein deutscher Forscher hat herausgefunden, dass den Unterschied die Spucke macht.

Menschenaffen sind vom Genom her eng verwandt mit dem Menschen, bei Schimpansen gibt es eine Übereinstimmung von 98 Prozent. Aber der Speichel unterscheidet sich überraschend deutlich. Einer der Gründe könnte die Sprechfähigkeit des Menschen sein: Flüssigere Spucke schützt vor trockenem Mund.
