A new study has found that shellfish species harvested by humans tend to be more genetically resistant to disease. Researchers from the University of Southampton and the University of Exeter studied shellfish species that have been harvested by humans for centuries and compared them to species that have not been harvested. They found that the harvested species had higher levels of genetic resistance to disease than non-harvested species. This suggests that humans may have unintentionally selected shellfish with greater genetic resistance to disease, making them more successful in the wild. This research could help inform conservation efforts aimed at protecting and managing shellfish species in the future.
