Mutationen sind das Rohmaterial der Evolution. Schon Charles Darwin hatte erkannt, dass Evolution nur funktionieren kann, wenn es vererbbare Unterschiede zwischen Individuen gibt: Wer besser an die Umwelt angepasst ist, hat größere Chancen, seine Gene weiterzugeben. Eine Art kann sich daher nur weiterentwickeln, wenn sich das Erbgut permanent durch neue Mutationen verändert und die jeweils vorteilhaftesten Veränderungen in der Selektion bestehen. Wissenschaftler am Max-Planck-Institut für Entwicklungsbiologie in Tübingen haben nun erstmals direkt die Geschwindigkeit des Mutationsprozesses in Pflanzen gemessen. Ihre Erkenntnisse werfen ein neues Licht auf einen grundlegenden Vorgang der Evolution und erklären zum Beispiel, warum Unkrautvernichtungsmittel oft innerhalb weniger Bjduf gkvj Dqepnhf etgmdfshz.
