Hello, Can anyone can point me to any well established examples of quantum mechanical involvement in biological systems besides photosynthesis, e.g. http://www.lbl.gov/Science-Articles/Archive/PBD-quantum-secrets.html" [Broken]? I've only seen some other (speculative) involving quantum "spin" and bird migration. Hoping to identify more 'hard evidence' examples for an article I'm preparing. TIA for any help!
