It's always been quantum
"Scientists were very dubious as to whether these phenomena were active in the “warm and wet” conditions of living cells, but it turns out that on a minute scale, particles within living cells obey the same principals as those in non-living molecules."
This seems to me to be not just a sweeping statement but a wrong statement. Chemical reactions at the molecular level are quantum processes, dependent on stuff like quantized energy levels in electrons and ions. This applies to cell chemistry as much as inorganic chemistry. Another immediately obvious quantum effect is vision, depending on the corpuscular nature of light.
