Radiation from the leaking Fukushima nuclear plant following last year's tsunami caused mutations in some butterflies and damaged the local environment though humans seem relatively unaffected, researchers say.
Radiation that leaked from the Fukushima nuclear plant following last year's tsunami caused mutations in some butterflies _ including dented eyes and stunted wings _ though humans seem relatively unaffected, researchers say.
Although the damage is irreversible, the species could develop resistance to the radiation, Otaki said.
"In that case, we will observe adaptive evolution," he said.
