Wissenschaftler im Deutschen Krebsforschungszentrum in Heidelberg haben eine neue Tierart entdeckt: Der Marmorkrebs, Procambarus virginalis, ist vermutlich vor 30 Jahren in einem einzigen Schritt aus dem Everglades-Sumpfkrebs hervorgegangen und hat sich seither weltweit verbreitet. Alle bisher untersuchten Tiere sind weiblich, pflanzen sich ohne männliche Hilfe durch Jungfernzeugung fort und weisen exakt das gleiche Erbgut auf. Daher müssen durchaus vorhandene Unterschiede einzelner Exemplare in Aussehen oder Verhalten auf epigenetische Vorgänge zurückzuführen sein. Weil auch die Krankheit Krebs häufig epigenetische Ursachen hat, ist der Marmorkrebs ein höchst interessantes Modell für die Krebsforschung.
