The story moves on to genetics, where one Per-Olov Lowdin is quoted as saying: “The genetic code that makes life possible is inevitably a quantum code.”

Evidently not. You can write the code down on paper, then reconstruct the molecule from scratch. So it's a classical code.

It is suggested a tad unscientifically that: “Quantum weirdness could be playing a role in the mutations that drive evolution.”

I recommend Greg Egan's "Teranesia" for an exploration of that kind of idea. It's unlikely though. High parallelism and random feelers through the search space are good enough. Moreover, one would need to find out what function releated to "driving evolution" would be computed more efficiently via a quantum computer than via bog-standard classical one. Things always go south once has to get the classical bits out of the quantum system, with additional randomness introduced. The complexity BQP is well-defined nowadays, have at it!

The book goes on to describe the work of Roger Penrose, who theorised that the human mind is a quantum computer.

Not that shot again. Penrose also things we think by logical deduction and that Gödel's incompleteness theorem somehow applies. Please!

“Perhaps death represents the severing of the living organism’s connection with the orderly quantum realm, leaving it powerless to resist the randomising forces of thermodynamics.”

What the hell am I even reading? Death represents the randomization of large hierarchy of processes that were going off the rails a bit before death. As for the "quantum realm" (what is that?) being "orderly", I think a famous cat, possibly gassed, has something to say about that.
