Der evolutionäre Ursprung unserer Zähne
Bislang war umstritten ob die frühesten Wirbeltiere, die Kiefer hatten, schon Zähne besassen oder nicht.
Virtueller Schnitt durch den Kiefer des Panzerfisches Compagopiscis
Now, an international research team has shown that the jaws of the prehistoric fish Compagopiscis already had teeth. This demonstrates that teeth appeared at the same evolutionary time as jaws – or at least shortly afterwards.
The leaders of this project were scientists from the University of Bristol, England, who carried out their decisive experiments at the SLS at the Paul Scherrer Institute, Switzerland, where they were able to actually look inside Compagopiscis fossils. The results of this research have just been published in the latest edition of the journal Nature
