Hightech-CT offenbart evolutionäre Anpassung ausgestorbener Krokodilverwandter beim Übergang vom Land ins Wasser

(PresseBox) (Berlin, )
Der Baum des Lebens ist reich an Arten, die vom Wasser aufs Land übergegangen sind. Einige Arten nahmen jedoch die entgegengesetzte Richtung. Neue Einblicke in die Anatomie des Innenohrs des prähistorischen Reptils Thalattosuchia enthüllen jetzt Details über einen dieser Wendepunkte der Evolution. Während des Mesozoikums gingen die ausgestorbenen Krokodilverwandten nach einer langen halb-aquatischen Phase vollständig zur marinen Lebensweise über. Während dieses Prozesses passte sich das Skelett der Thalattosuchia schrittweise an den neuen Lebensraum Wasser an. Insbesondere die Anpassung des Gleichgewichtssystems im Innenohr dieses Reptils führte zu einer verbesserten Schwimmfähigkeit. Im Vergleich zu Walen, die sich ohne längeres halb-aquatisches Stadium schnell lk qzz Uqnvq yw Szdqjd dpcjbdwxt, gqy jjrw abk pjjvuxbgff hzrqhjv Ueqnfrnhxrfnwr kut xievkfbfp lpnqxrjv.
