That's my point. It will make more sense once you've read the article.
It's only 8 pages long.

Er, Joe, how can eight page paper make sense if the thesis stated in the
abstract doesn't make sense? I mean, the final sentence of the abstract
is the paper's thesis, isn't it? Masatoshi Nei wrote:

"It appears that the driving force of phenotypic evolution is mutation,
and natural selection is of secondary importance."

It seems obvious to me that whatever mutations occur can have no effect
on the phenotype unless they confer some adaptive advantage, or unless
the owner of that new mutation has some other adaptive advantage that
permits or enables genetic drift. In either case, natural selection will
be the "driving force," by which I presume Masatoshi Nei refers to the
event(s) that initiate some more or less permanent change in a species'
phenotype.

The most charitable interpretation of Masatoshi Nei's paper is that he's
quibbling about the semantics of 'driving force.'

I was going to but I'm not willing to spend money to do so.

I share the concern of others but differ slightly.
If someone asked me what drove the consumer market
the production of goods or its cosumption I'd
just look at them quizically. Consumers cannot buy
that which is not produced but production isn't
sufficient cause for consumption despite some people's
vigorous assertion of a variant of "Say's law"
that goes "production creates its own demand."
