I feel like the author was either trying to write to a pretty lay audience or didn't understand the broad applicability of quantum mechanics. There is no threshold either where things are "classical" or "quantum". The systems that may be satisfactorily described by classical mechanics are just those in which the Planck constant may have a value of zero. While in modeling a system using quantum mechanics, it has a finite value.

Computational chemistry is based on different approximation methods for evaluating the interactions of a molecule with another. These methods work well, and as you can imagine form a large portion of biochemistry. Saying "Biology may not be quantum.." in the title seems pretty misleading at best.

Most of the interview quotes are researchers talking about any sort of long term coherence used in a biological organism. The article mentions this in brief but I didn't see a link. For a real cool example of biology pushing quantum limits check out the magnetic field "vision" of birds [0].
