Zur Evolution von Weichtieren (Mollusken), z.B. Schnecken, Muscheln und Tintenfische, gibt es noch viele offene Fragen. Die Arbeitsgruppe um den Zoologen Andreas Wanninger von der Universität Wien hat den Entwicklungszyklus eines einfach gebauten, wurmförmigen Vertreters dieses Tierstammes untersucht. Dabei fanden sie heraus, dass die Larven der zu den Furchenfüßern gehörenden Art Wirenia argentea eine weitaus komplexere Körpermuskulatur besitzen als die erwachsenen Tiere - erst im Laufe der Metamorphose kommt es zu einer Vereinfachung ihres Körperbaus. Dies deutet darauf hin, dass die Tiere von einem komplexer gebauten Vorfahr abstammen. Die Ergebnisse dieses vom FWF geförderten Forschungsprojekts erscheinen aktuell im renommierten Fachjournal Yfarbfo Lyzwbhy.
