I learned in university that the first fish with 4 legs were fully aquatic. They developed them to walk on the ground of the ocean and later used them on land. That would make it a pre-adaptation. So the drawing has the evolutionary steps wrong. Would you agree on it? I’m just curious
I think that’s what I meant. The legs weren’t as developed as I remembered them but neither were they an adaptation after going on land. So the image is right after all, I just underestimated the limbs in the picture and overestimated the limbs of the transitional creature I learned almost a decade ago (so still after 2008). Thanks!

You should read up on the Tiktaalik. It is a relatively new discovery in 2008. It show that there was any evolutionary step.
