Introduction: The scientific name for great white shark is Carcharodon carcharias. Great White Sharks live and hunt on the coast of every continent in the world the except Antarctica because they can only survive temperatures from 54 to 74 degrees fahrenheit . Most of the world’s Great White Sharks live off the coast of Dyer Island, in South Africa, this area is also referred to as “Shark Alley.” Most people survive Great White Shark attacks because typically, after mistaking a person for prey, a shark will take a bite, realize their mistake, and swim away so they are kinda friendly when they realize its a human and not it's prey. The habitat for great white sharks are the ocean and sea.

Molecular Evidence: Some of the most familiar to great white sharks is hammerhead shark, tiger shark, whale shark,grey reef shark, and white-tipped shark. The great white belongs to one of the oldest groups of sharks: the mackerel sharks. The similarities of the sharks is the jaw and gills it is the same.
Homologous Structure: A great white shark rib cage is similar to a human's rib cage. In a human's rib cage we protect the heart and the lungs. In a great white shark rib cage they protect the gill arch which helps them breathe underwater. Homologous Structure is an animal or human has the same structure as a human or animal but have different functions. This helps to explain evolution because the animals/humans had a common ancestor with the same structure.
Vestigial Structures:There are one or two fins present along the dorsal mid-line called the first and second dorsal fin. These are anti-roll stabilizing fins. These two fins may, or may not have spines at their origin. When spines are present they are defensive and may also have skin glands associated with them that produce an irritating substance. They use their ribs for structural support, just like all fish. Sharks are boneless fish, so very primitive evolutionarily-they harken back a few hundred million years, without very much change.
Transitional Fossils: The great white shark looks like a normal shark but has more white. The hammerhead shark jaw is bend down to have more things in your mouth. The grey reef shark jaw is longer than both a hammerhead shark and great white shark. A transitional fossil is any fossilized remains of a life form that exhibits traits common to both an ancestral group and its derived descendant group. This helps evidence of evolution because it talks about the fossil animal.
This is a grey reef shark.
This is a hammerhead shark.
Comparative Embryology: Comparative embryology is the branch of embryology that compares and contrasts embryos of different species. It is used to show how all animals are related. Many things are compared (such as whether or not the organism has a notochord or gill arches). It provides evidence to evolution because it shows how animals are related in one way or another.
