Great White Shark By: Sunny Kim


Great White Sharks also known as the great white, white pointer, or white death, is a large shark that can be found in coastal surface of all the major or big oceans.


The Great White Sharks are mainly found around the coastal areas of all the oceans. They typically live on the outskirts of shore waters, but sometimes they go into the deep waters. If they do go down into the deep waters, they can go down to 1000 meters deep.

Geologic Times

They were found during Silurian period. During this period they were found in Siberia and Mongolia. From today, it's been 420 million years ago since they Great White Sharks have been discovered.

-Morphological/Molecular evidence-

Closest relatives

The Mackerel Sharks are the closest and oldest relative to the Great White Shark. They have similar body forms and actions like, having big months that extend behind their eyes. They also fall into a group together for being smart and fast swimmers throughout the ocean.

Evidence of evolution

Although there isn't an exact percentage to how close these two sharks are, based on their appearances and how they adapt to the environment shows proof of evolution. Between both of them, they have wide and big mouths to catch for food. They have similar body structures and in a way, personalities.

-homologous structures-

In Great White Sharks, the jaws are different compared to other types of sharks. When they go hunt for food, they lose teeth from biting down, but it grows back fast. Also their jaws are wide and big , which makes it easier for them to catch their prey. This homologous structure is very similar to the Mackerel Shark because of the form and shape of both their jaws.

Evidence of evolution

These traits of the Great White Shark could've passed down from many other types of sharks before their time. The jaw and their abilities to hunt are similar to the Mackerel Shark. They both have very similar movements and actions based off their body forms and shape. This is one of the examples to many others of homologous structures.

-Vestigial structures-

What are their vestigial structures?

Sharks are boneless fish. Throughout the time of their existence, there isn't much of a change through their evolution. Although they do have ribs to support themselves.

evidence of evolution

Since there aren't many bones through the shark's body, the evidence of evolution is small. There are some changes through the years, but very small changes.

-Transitional fossils-

Is there proof that they have fossils?

About 450 million years ago, the first shark teeth were found. Towards the Late Ordovician period it was discovered. It was the very first fossil that was found.

Evidence of evolution

When the first tooth was discovered, the shapes and sizes changed through the years. This shows evidence of evolution because little changes are happening to the bones of the shark.

Comparative embryology

Evidence of evolution

Comparative Embryology shows us how the development of the animal changed throughout the years of it's existence. For Great White Sharks, the gill slits changed and it expanded. The size changed and the shape changed. This proves there's evolution because the gill slits from the previous had different size and shapes and it changed overtime.
