Plants can convert sunlight into energy at the 95% rate in microseconds. We poor humans do it at 20% rate.- "Was the exploitation of quantum effects in photosynthesis driven by evolution to achieve the extraordinary efficiencies, or in other words did quantum transport outcompete other mechanisms during evolution? Are there other biological processes in which quantum effects play an important role? In the case of light-harvesting proteins quantum transportation allows extreme transport energy efficiency and robustness."-http://www.sciencedaily.com/releases/2013/06/130620142932.htm- "The most surprising discovery was that the transport paths within single proteins can vary over time due to changes in the environmental conditions, apparently adapting for optimal efficiency. 'These results show that coherence, a genuine quantum effect of superposition of states, is responsible for maintaining high levels of transport efficiency in biological systems, even while they adapt their energy transport pathways due to environmental influences'"-All I can say is, "WOW". All from a chance mechanism. No way.
Quantum photosynthesis proven

It has been suspected but now in proven:

"... quantum effects are typically limited to the very small, and only really observable in perfect, laboratory conditions. A living being, with its wet, messy systems, would be a tough place to find some quantum weirdness lurking — and yet we have.
"Scientists zoomed in on the Fenna-Matthews-Olson (FMO) complex, a key component of green sulfur bacteria’s machinery for photosynthesis. It’s been a historical favorite for such research because we’ve long known its structure and it’s fairly easy to work with.
"Previous experiments had seemed to show light-sensitive molecules in this area in two different states at the same time — that’s quantum weirdness — but the effect lasted more than 1 picosecond, which is much longer than expected. This new study shows that it was really just regular vibrations in the molecules, nothing quantum about it.
"But researchers have been excited about the possibilities of quantum biology for years, so having disproved the earlier experiments, the authors wanted to find some new evidence of their own. “We wondered if we might be able to observe that Schrödinger cat situation,” says co-author Thomas la Cour Jansen in a press release.
"And observe it they did! With a technique called two-dimensional electronic spectroscopy, researchers saw molecules in simultaneous excited states — quantum weirdness akin to a cat being alive and dead at the same time. What’s more, the effect lasted exactly as long as theories predicted it, suggesting this evidence of quantum biology will last. As the authors succinctly put it, “Thus, our measurements provide an unambiguous experimental observation of excited-state vibronic coherence in the FMO complex.” What could be simpler?
"The results shed light (haha) on how to harvest energy from light, and the team thinks they’re “generally applicable” to a variety of systems, living and non-living alike. This means it could result in engineering benefits such as better solar panels, energy storage or even quantum computers. And, of course, updated textbooks for tomorrow’s lessons on photosynthesis."
Comment: Quantum effects in living biochemistry has been doubted because life is a wet state. Now we have this demonstration, my theory that consciousness is a quantum state in the brain becomes more reasonable.
