Genomische und epigenomische Analysen zeigen Artenentstehung ohne scharfe Trennung in isolierte Bestände

(PresseBox) (Berlin, )
Damit sich eine neue Art bilden kann, müssen nach gängiger Lesart meist mehrere Bestände existierender Arten vorhanden sein, die voneinander getrennte Fortpflanzungsgemeinschaften bilden. Deren Isolation ermöglicht ein langsames Auseinanderentwickeln der Genome und dadurch die Bildung neuer Arten. Ein internationales Forschungsteam mit Beteiligung des Leibniz-Instituts für Zoo- und Wildtierforschung (Leibniz-IZW) und der Universität Haifa hat nun einen Fall der Artbildung innerhalb eines gemeinsamen Genpools rekonstruiert: Die fünf in Israel lebenden Nagetierarten der Gattung Spalax entstanden aufgrund klimatischer Veränderungen der letzten eineinhalb Millionen Jahren in unterschiedlichen Regionen des Landes sowie durch kleinräumige Anpassungen an spezifische Gesteinsverhältnisse in ihrem Gebiet.
