Why not expect to escape from cockroaches

Mankind cannot escape cockroaches because of the genes of these insects "remember" too much poison - Ilya Gomyranov, Press Secretary of MGU Zoological Museum told Sputnik.

" We are certainly not capable of destroying cockroaches , nor do we have to - after all, they are one of the components of the urban ecosystem, as well as pigeons with mice. We can reduce the number of cockroaches, comply with hygiene standards in public places (entrances, landfills, etc.) as well as in our own apartments, " the scientist said.

Cockroaches are the length of DNA that ranks second among insects.

Gomyranov expert reminded that in the 80s of the twentieth century, pesticides appeared on the basis of "delicacy" with cockroaches that were mixed with toxic substances. However, over 10 - 15 years, many cockroaches have "known" and stopped eating poisonous baits, making use of pesticides useless.

The thickness of experience evolves

Cockroaches appear on Earth about 235 million years ago. Over hundreds of millions of years of cockroach existence, its representatives have encountered and dealt with poisons similar to modern ones and the memory of these "encounters" is stored in the DNA of cones. coincidentally, the conversation partner with Sputnik said.

He explained that cockroaches are the length of DNA that ranks second among insects and exceeds the length of human DNA.

According to Gomyranov expert, evolutionary experience accumulated over generations to help cockroaches identify food and distinguish safe substances from poisons. In addition, to adapt to toxins, cockroaches do not need to evolve, just activating the old genes is enough.

"In an insect's body produces a large amount of protein detoxification, acting as a" drug "against different types of toxins," the scientist said.
