The mystery of water bear worm suicide, a large number of water bear worm bodies were found under the ice in Nanjing. Why do water bears commit suicide collectively?

Water bear worms can survive for several years in a dehydrated state, even in a vacuum environment in space. They are extremely cold-tolerant, can survive in an environment of -272.8℃, close to absolute zero, and can stride forward in the high temperature of 15 1℃. The earth has suffered five mass extinctions, and the water bear worms seem to be all right, but they are under the Antarctic ice 1000 meters.

20 18, 18 at the end of February, scientists drilled a hole in the William ice sheet in Antarctica, which opened the door to the mysterious world under the ice. After a preliminary analysis of the samples, scientists were surprised to find that the water bear insects overturned, including some ancient crustaceans and water bear insects. Although the temperature under the ice is extremely cold, there is still oxygen and even bacteria active. Although the conditions here are not suitable for the survival of larger creatures, this is a water bear worm. Why did it die? Some netizens said that the water bear worm must have committed suicide. Because invincible, so lonely and then choose to commit suicide. Or no one can kill it. Much as I want to believe it, this statement still doesn't make sense.

Animal ecologists believe that the owners of these remains may not live under the Antarctic ice, but they may have entered Lake Mercer with the current and then got trapped under the ice. As for the mystery of the death of the water bear worm, it is necessary to determine its survival age by radiocarbon dating, and then analyze its DNA to find clues about its activities before its death, and finally solve the mystery.

In short, although the water bear worm is a "super species" with strong viability, the existing life record is only 120 years, and it is normal to be found dead occasionally.
