EEB's Agrawal retraces monarch’s toxin-immunity evolution

Small genetic changes prevent a normally fatal poison from killing monarch butterflies. By editing these genes into laboratory fruit flies using CRISPR technology, Agrawal and collaborators have reconstructed evolution and instantly conferred – in fruit flies – the same toxin resistance enjoyed by monarchs.
