Even ignoring the uncalled-for dig at evolutionary biologists (a broad
class of biologists, which includes molecular biologists and cannot be
included under the blanket category of loonies which Mr. Hall would
seem to prefer), the above quote betrays the very scientific
provincialism from which the field of evolutionary biology is finally
beginning to emerge, even if Mr. Hall's personal field isn't.  _The
Selfish Gene_ is a book by Richard Dawkins, which advocates a
particular perspective from which to think about evolution: the
perspective that hypotheses of adaptation in biology should be
explained in terms of the transmission advantage they offer to
particular alleles, rather than simply the number of offspring they
allow individuals to leave.

While it is unfortunate that Dawkins' terminology overlaps that of
"the molecular biologist," those who are informed are aware of this
overlap, and are able to judge which meaning is intended.
