Tihohodka – the most tenacious creature on Earth

Tardigrades will survive all possible global catastrophe.

Microscopic invertebrates tardigrades will survive all other organisms on the planet in case of global catastrophes on a cosmic scale. This is stated in the article the scientists of Harvard and Oxford in the journal Scientific Reports.

Studies have shown that tardigrades will exist on Earth for at least another ten billion years, much more than the human race and other species.

In 2007, researchers found that cichodajki can survive after a long stay in outer space and even multiply in conditions of complete weightlessness and the lack of food and water.

It is noteworthy that 18 percent of the DNA of animals “borrowed” from other organisms – bacteria-extremophiles, plants, fungi and archaea.

Last year, Cryobiology revived two animals who spent three decades in the frozen Antarctic mosses in a state of suspended animation . After defrosting, they were able to continue the race.

And recently, scientists have discovered that cells of animals contain unique proteins that protect them from lethal doses of radiation.

Armed with these facts and knowledge, what space disasters may threaten Earth, scientists decided vicenity that can kill the animals.

They considered three scenarios of possible disasters that can destroy life on earth in the next billions of years: the impact of a large asteroid, a supernova explosion in the solar vicinity and gamma flash.

“To our surprise, we found that although the explosion of nearby supernova or an asteroid strike would be a disaster for humanity, tardigrades will not be affected,” explained Dr David Sloan from the University of Oxford.

Researchers believe that the vitality of the animalcules, repeatedly proven in ground and space experiments, is a serious argument in the assumption of life on other planets.

Economists said that humanity with a high probability to live no more than 700 years.

According to the forecasts of astrophysicists, the Sun will engulf the Earth in about 5-7 billion years.
