Worms Go Supersize in the UK

A new breed of super worms that feed on lead, zinc, arsenic, and copper were found at disused mining sites in England and Wales. It’s thought that the newly evolved worms and their toxic eating habits could help cleanse polluted industrial lands as their excretions produce different versions of the metals, which allows plants to grow. Scientists believe their ability to tolerate extremely high metal concentrations has affected their evolution.
