Sharks 2 heads appear much, and the underlying cause is very worrying

It seems that only in movies, but reports that the first two sharks appear more and more. What is the reason?

Two-headed sharks - this name seems to be only in Hollywood horror movies. But in recent years, the rate of shark head 2 appear more and more naturally. In 2013, a Florida fisherman caught a pregnant cow shark. Inside there are eggs, containing a two-headed fetus.

Or as of 2011, two-headed blue sharks were also discovered in California Bay. Blue sharks are also the species with the highest rates of producing two-headed sharks, because they produce a lot - up to 50 individuals / litter.

The first two sharks appear more and more, but no one understands why.

Even in early 2016, experts from the University of Malaga (Spain) discovered a two-headed shark embryo in the laboratory environment - which is considered the most perfect for the development of the organism.

The problem is that, experts still don't understand why this happened.

According to National Geographic, it is clear that these shark embryos have encountered a problem in genetic genes. Nicolas Ehemann, an expert at the University of Malaga, said the gene for the mutant shark is stronger, and the problem is that they do not come into contact with any chemicals or radioactive substances.

Why? Ehemann said that people are the cause, but specifically that we exploit aquatic products too much.

According to her, overexposing fish to limit shark genetic diversity , making instability in the gene more likely to show up, creating two-headed shark.

The body of two-headed sharks cannot grow well, and life is very short.

But what about the first two? The problem is no big deal, just a body that is difficult to nourish two brains. The body of two-headed sharks cannot grow well, and life is very short.

Direct causes still need more research to determine. However, experts also believe that people need to change soon, if not to destroy the future of many animals in the world.
