Ok, you can keep count. I think the outline is worth
skimming, especially the beginning. That would take
you
about a minute or so.

That sounds like another "yes" vote.

The article is not incorrect about experiments in
which
buckeyballs display wave-particle duality. Of course,
the two-slit experiment (shooting things through a
vacuum at two slits) is rather far removed from
conditions in the cell.

HOWEVER, as the outline points out, it is only certain
small sections of a DNA molecule which need to
experience quantum effects for quantum evolution to be
a possibility, not the entire molecule, and the scale
involved is similar to scales in which quantum effects
have long been known to effect chemistry, with
molecular structures of molecules being a
superposition of two or more possible structures.

I'm glad Anders brought that up, because quantum
evolution's potential to be one explanation for
adaptive mutations is one of the reasons why it's
worth looking into. Of course, many
still dispute the evidence that adaptive mutations
exist.

(If quantum evolution survives scrutiny and becomes
widely accepted, the scientists who steadfastly denied
that adaptive mutations were taking place will quietly
change their minds, usually without admitting they
were wrong.)
