This sounds to be very similar to that of some of the dinosaurs from many years

2. THERE ARE NO CONSISTENT TRENDS IN EVOLUTION: In the evolution of sharks, we clearly see that there are no consistent trends in their evolution from the beginning of their existence, they are a species that are always changing or evolving as mentioned in the previous example. This is why we see the diverse amount of species of the shark family all over through the ages both prehistoric and present. And can clearly see the branching out of the species from is simplest form to various other forms, the branching of the shark family can be seen
