The sharks have been on Earth for nearly 400 million years, but it is a variant of the white, who lives in the Mediterranean sea, is about 3.2 million years old, significantly longer than experts had previously thought, according to a new study.

The study, which was published in the Official journal of Biogeography, looked at the DNA sequences of the Mediterranean, the white shark, and found them to be closer, genetically, to those that are in the Pacific Ocean, those that live in the Ocean.

“White sharks have a complex evolutionary history, they are rare,” the study’s lead author, Agostino Leone, said in a statement. “They have evolved into a sedentary population groups are distributed all over the world. Among these, the Mare Nostrum consists of airy guestrooms with white sharks, which are truly unique.”

“White sharks in the Mediterranean sea, has a very low genetic variability (hrv), which may be indicative of a very small and endangered group of sharks,” Leone added.

Mediterranean great whites are not as well studied as the other great whites, particularly as a result of the population decrease. In August, 2019 at the latest, Fox News has reported that a great white had been spotted off the South Africa for a period of 18 months, astonishing experts.

In an effort to resolve the lack of research, experts have begun to study the teeth, jaw, and neck over the past 200 years, in museums and in private collections. Thanks to the technological advances in DNA sequencing, the researchers were able to compare the view of the Mediterranean sea, the great whites to other white people all over the world.

“This new data has allowed us to maintain the bio-diversity of white sharks live in the Mediterranean sea,” said Leone. “Through the analysis and comparison of the different samples, we were able to estimate that the white shark population in the Mediterranean was different from the other cognate populations of around 3.2 million years ago. This essentially proves that the theories about the sharks and colonization from the Mediterranean sea, about 450,000 years ago, are in the wrong.”

WHAT IF THERE WERE NO SHARKS?

Leone and the other, the researchers found that the Mediterranean sharks has been formed in the north Pacific ocean, traveling through the Central American waterway in front of the Isthmus of Panama was formed about 3.5 million years ago.

As a result of the shift in the geographic landscape, a number of drastic changes in the climate that may have resulted in a number of species became extinct, what are the consequences for big species of fish in the sea.

In view of the low population density in the Mediterranean sea, Leone said, and it is probable that these great white sharks are a small, threatened community.”

“In order for them to be saved, it is essential to act quickly: the rate would be detrimental to the ecological balance of the Mediterranean Sea as well as on what is already a very unstable global situation of this magnificent sea-predators,” Leon explained.
