An article published in the journal “Science Advances” reports a study on Australian lungfish (Neoceratodus forsteri) that offers new information on the evolution of fish fins into tetrapod limbs. A team of researchers led by Dr. Joost Woltering of the German University of Konstanz studied, in particular, the anatomical and genetic characteristics of Neoceratodus forsteri’s embryos. The result was the confirmation of the importance of some genes with new information on the genes involved and the discovery of a primitive hand in this fish’s fins, suggesting an evolution of fingered limbs through embryonic changes.
