Evolution Of Shark Evolution

THE EVOLUTION OF THE CARCHARODON CARCHARIAS (SHARK)

for my research task, I chose to study and track the evolution of the shark. These beasts being one of nature’s top predators in the world and dominating the oceans surrounding our continents. I chose these fierce creatures as they were a perfect example for me to use in explaining the evolution and the branching of evolution purely based on the fact that they have been around for millions of years through prehistoric times changing and evolving into different forms living in different areas and different depths of the world, as we see they are a large amount of shark species in the oceans all coming from one place. Which will be discussed in further detail throughout this research task.

From what scientists call the Carboniforous period sharks really branched out and took on different shapes and sizes with many different features in different species, this event is known as “The golden age of sharks” these sharks though, very different from the modern sharks that we find today. During the Jurassic periods sharks flourished and after this the diversification of the species was over and they barely changed for millions of years thereafter. Only when the huge meteor struck the earth were many of the shark species eliminated but few survived and still roam the oceans

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
