Jean-Baptiste Lamarck hätte seine Freude: Seine Überzeugung, dass Lebewesen erworbene Eigenschaften an ihre Nachkommen weitergeben können, ist seit kurzem unter Genetikern wieder gesellschaftsfähig. Die Transformationslehre, die Lamarck vor rund 200 Jahren veröffentlichte, ruhte seit dem Siegeszug von Darwins Evolutionstheorie in der Mottenkiste der Geschichte. Seit einigen Jahren weiß man jedoch, dass Umwelteinflüsse durchaus ihre Spuren im Erbgut hinterlassen können - in Form so genannter epigenetischer Veränderungen. Die erste umfassende Bestandsaufnahme spontan auftretender Unterschiede legen nun Wissenschaftler des Max-Planck-Instituts für Entwicklungsbiologie in Tübingen vor. Am Beispiel der Ackerschmalwand Arabidopsis thaliana bestimmten sie, wie häufig und in welchen Bereichen des Genoms epigenetische Ejiwurtfeozmuy ngswegfyg - kkr qmr aeuxffl pmz ykiylm rhyysgznjgwc.
