The zebrafish jaw is representative of the gnathostome fish template and can be used to understand both how the osteichthyan plan arose, and how it was modified over the course of evolution. Zebrafish jaw morphology builds on the pharyngeal structures of jawless vertebrates and early gnathostomes, where elements are added and specialized in ...Shark Evolution. Most scientists believe that sharks came into existence around 400 million years ago. That's 200 million years before the dinosaurs! It's thought that they descended from a small leaf-shaped fish that had no eyes, fins or bones. These fish then evolved into the 2 main groups of fish seen today. The answer is that hundreds of millions of years ago, vertebrates were far from the dominant life forms in the earth's oceans, and these early fish needed a means of defense against giant "sea scorpions" and other large arthropods.
