I would like to hear some thoughts about the quantum effects that seem to be an important part of the photosynthesis (http://www.lbl.gov/Science-Articles/Archive/PBD-quantum-secrets.html" [Broken]). According to the scientists who made this discovery it seems that the photon tests all possible paths and then the most effective one is chosen. If that theory is correct it seems to contradict all popular interpretations of QM. (am I right?) Or does anyone believe that an effect like this can be explained with any of the common interpretations (many worlds for example). Is there any discussion at all that tries to explain what's going on in the photosynthesis? I assume there are no definitive answers right now but I would like to hear your comments and if anyone has good links, please share.
