Unseren frühen Vorfahren in den Kopf (und in die Nase) geschaut

(PresseBox) (Villigen PSI, )
Der Umbau des Gehirns und der Sinnesorgane dürfte den Erfolg der Wirbeltiere, eines der grossen Rätsel der Evolutionsbiologie, erklären - so die Aussage einer Arbeit, die ein internationales Forscherteam in der neuesten Ausgabe des Wissenschaftsjournals Nature veröffentlicht.

Die Forschenden konnten das Rätsel durch Untersuchungen des Gehirns eines 400 Millionen Jahre alten versteinerten kieferlosen Fisches aus der Klasse der Galeaspida lösen - eines evolutionären Bindeglieds zwischen den heute lebenden kiefertragenden Wirbeltieren und den Kieferlosen.

Die Untersuchung wurde gemeinsam von Paläontologen und Physikern der University of Bristol, England, des Instituts für Paläontologie der Wirbeltiere und Paläoanthropologie IVPP, China, des Muséum zplsdncg z'Zejrfjka lpcfrthrh Tcrxp, Yzmokvaulz ywl hyu Gjfs Srudkldu Fewskzwan cibzxevvkzbs.
