Until 30 years ago, the world of crayfish that is not on the earth began to invade the world. The reason for the rapid proliferation is that mutation does not require men to reproduce.
According to a recent study, the roots of the crayfish, known as the spotted crayfish, are based on a single gene that can reproduce by itself through a mutation in DNA.
Spotted crawfish is sold in Canada despite the warning that it should not be fed at home. The 10-legged mutant species was banned by the European Union.
According to the BBC Turkish language, the scientific name Procambarus virginalis was no more than 30 years ago. But now in Japan, Madagascar, Sweden and the United States is seen in the wild.
In a study published in Nature, Ecology an Evolution (Nature, Ecology and Evolution), it was stated that invading crayfish threatened native crayfish species in Madagascar.
If you have a spotted crayfish, it will be 200 or 300 in three months.
From research team. "If you have a spotted crayfish, it will be 200 or 300 in three months," Wolfgang Stein said in a statement made by Canadian state television CBC. In fact, scientists who study how this fresh water crayfish is made alone can better understand how cancer spreads.
Well, how did it come out?
Everything started in a pet store in Germany in the 1990s. A Florida native species, a scaly crayfish, came to the world with an additional chromosome sequence.
So he began to move without a man. These crayfish, which are born from the teeth, also produce hundreds of eggs each time.
These genetically duplicated crayfish have shown great interest, especially among the aquarium buffs in Germany
However, when species grow extreme in just a few months, people leave their spotted crayfish in ponds throughout Europe. Crayfish, brought to the country as a cheap protein source in Madagascar, are now threatening native species.
In the two states of the EU and the United States, spotted crayfish were forbidden. However, the species continues to reproduce in the wild.
