Alternative Besiedlungstheorie des Himalaya?

Molekular-genetische Daten untermauern Hypothese erstmals für Wirbeltiere

(PresseBox) (Leipzig, )
Bislang galt die Tierwelt des Himalaya als "Einwanderungsfauna", deren Arten seit der geologischen Heraushebung der Gebirgskette vorwiegend von westlich und östlich angrenzenden Regionen eingewandert sind. Ein deutsch-chinesisches Forscherteam hat jetzt mittels molekular-genetischer Methoden eine alternative Besiedlungstheorie an Krötenfröschen getestet. Die Ergebnisse legen nahe, dass diese Gruppe bereits im geologisch früher angehobenen Südtibet entstand und von dort aus den Himalaya besiedelt hat. Die Einwanderung und Evolution vieler Arten im Himalaya müsste damit anders verlaufen sein, als bisher angenommen.

Der Himalaya ist einer der weltweiten "Hotspots" der Biodiversität, tausende Arten gelten noch als unentdeckt oder wissenschaftlich nicht beschrieben.
