Evolution of tetrapods for a magazine article. By Maija Karala:
"The animals depicted are, from bottom to top, Eusthenopteron, Panderichthys, Tiktaalik, Acanthostega, Ichthyostega and Pederpes. I tried to depict them as independent lineages instead of the often misunderstood linear progression. I also pointed it out in the text itself for a couple of times.
I only included the best-known fossils and left all the isolated jaw bones and head parts out, because I didn’t want to speculate too much.”
