Ausgestorbene Riesenschildkröte - 1000 Jahre alte DNA entschlüsselt

Genetische Untersuchung geben Einblicke in die Evolution der "Bahamas-Schildkröte"

(PresseBox) (Frankfurt, )
Wissenschaftler von Senckenberg und der Universität Potsdam haben das Erbgut der ausgestorbenen Riesenschildkröte Chelonoidis alburyorum untersucht. Dem internationalen Team gelang es erstmalig eine vollständige DNA-Sequenz der tropischen Tiere zu gewinnen. Das Erbgut offenbart, dass die Bahamas-Schildkröten nahe Verwandte der Galapagos-Schildkröten und der südamerikanischen Chaco-Schildkröten waren. In ihrer heute im Fachjournal der Royal Society of London "Proceedings B" erschienenen Studie zeigen sie zudem, dass die Tiere vom Menschen ausgerottet wurden.

Vor etwa 1000 Jahren waren die Bahamas noch die Heimat der Riesenschildkröte Chelonoidis alburyorum - dies änderte sich kurz nach der Besiedlung der Inseln durch den Menschen. "Heute finden wir nur
