For those materialists who claim that quantum mechanics only operates at the micro level and not the macro level are clearly dead wrong. As has been shown just recently for example quantum mechanics shows efficiency of photosynthesis. This is a published study in Nature Communications.
There is more also recently Stuart Hameroff's and Roger Penrose theory of ORCH theory has been gaining a lot of ground lately.
Here is a brief summary of the research link copied above.
"A review and update of a controversial 20-year-old theory of consciousness claims that consciousness derives from deeper level, finer scale activities inside brain neurons. The recent discovery of quantum vibrations in "microtubules" inside brain neurons corroborates this theory, according to review authors. They suggest that EEG rhythms (brain waves) also derive from deeper level microtubule vibrations, and that from a practical standpoint, treating brain microtubule vibrations could benefit a host of mental, neurological, and cognitive conditions".
Also, there is an interview with both scientist's discovering how thrilled they are that quantum vibrations have been found in the microtubules inside the brain. It is awesome that this theory is gaining support.
