It's Just Natural Selection

It's claimed that soil nematodes (threadworms), living near Chernobyl Nuclear Power station, have developed 'super powers'. These, almost ubiquitous multicellular little creatures, have a very short generation span. It's obvious that the radiation released in the Chernobyl accident, has exerted a strong selection pressure on these nematodes. Just as in the case of antibiotic resistant bacteria, the selection pressure has resulted in genetic lines who are not killed by exposure to something that destroys their peers (https://www.independent.co.uk/news/world/europe/chernobyl-worms-nuclear-power-plant-b2509161.html). In one way, it's somewhat reassuring that multicellular life is likely to persistent, even if humans really mess things up on the planet. At least we won't be going back to the bacterial phase.
