Wale ohne Beine, Menschenaffen ohne lange Schwänze – im Laufe der Evolution kommt es immer wieder zum Verlust von anatomischen Merkmalen. Beweise für deren einstiges Vorhandensein liefern Fossilien. Bei Fossilienfunden sind allerdings überwiegend nur harte Strukturen wie Knochen oder Zähne erhalten. Wie sich allerdings Weichteile evolutionär entwickelt haben, ist ungleich schwerer herauszufinden, da diese nur äußerst selten in Fossilien erhalten sind. Ein interdisziplinäres Forscherteam des Max-Planck-Instituts für molekulare Zellbiologie und Genetik (MPI-CBG), des Max-Planck-Instituts für Physik komplexer Systeme (MPI-PKS), der Senckenberg Naturhistorische Sammlungen Dresden und dem Senckenberg Forschungsinstitut und Naturmuseum Frankfurt hat nun am Beispiel der Entwicklung des Hodens bei
