That is some epic clickbait. The actual paper [1] is far less exciting. It does not talk about "terror pigs" nor "radioactive pigs". tldr; domestic pigs have been breeding with wild boar in a "wild area" devoid of humans. > We found that there were likely successful hybridization events in the evacuation zone ... we speculate two hypotheses ... (i) an abundant wild boar population caused increasing introgression of wild boar genes into the invasive pigs and a decreasing introgression of invasive genes into the wild boar with the increase in the distance from the invasion source. (ii) The pig legacy passed on to the next-generation hybrids was dependent on the ability of pigs to naturalize in the wild area of Japan. h1] ttps://royalsocietypublishing.org/doi/10.1098/rspb.2021.0874
