TED-ED: The strange case of the cyclops sheep - Tien Nguyen

Farmers discovered sheep with a deformity, leading scientists to find that wild corn lilies caused the condition through a molecule named cyclopamine. This molecule interferes with the hedgehog gene pathway, crucial for normal development. Decades later, researchers linked cyclopamine to potential cancer treatments, although it had side effects. Related molecules were developed into approved skin cancer drugs, showcasing how a mystery led to medical advancements.
