Größe der Keimzellen erklärt klassische Geschlechterrollen im Tierreich

Tübinger Evolutionsbiologen bestätigen Darwins Theorie der sexuellen Selektion

(PresseBox) (Tübingen, )
Unterschiede zwischen Männchen und Weibchen finden sich in fast allen Organismengruppen des Tierreichs, bezüglich des Verhaltens, des Stoffwechsels oder der äußeren Erscheinung. Typisch männlich, typisch weiblich – doch was sind die Ursachen für derartige Grundmuster? Die Frage nach der Existenz und den evolutionären Wurzeln solcher sogenannten Geschlechterrollen ist seit mehr als einem Jahrhundert Gegenstand kontroverser Diskussionen. Eine in der Zeitschrift Science Advances veröffentlichte Studie von Ines Häderer und Dr. Nils Anthes vom Institut für Evolution und Ökologie der Universität Tübingen in Zusammenarbeit mit Dr. Tim Janicke von der Universität Montpellier (Frankreich) und Dr. Marc Lajeunesse von der Universität Tampa (USA) zqggckuljcl yub, qiiq abjxtszfls Xknskkhanwbdrbpdcc ru Deuhymupu gaj bxfez siiz mtjufmzfhaigbe Fxxfklapwmzyrzvwhnmdnwr emcrcnmd.
