I would agree with this emphasis. Perhaps if there may be need to be more
on the evolutionary concepts as research tools that direct research programs
(i.e. determine the kind of research activities undertaken), and what kind of
new insights are generated.
Perhaps as an additional point regarding my questions about evolutionary
methodology, if one were to take, for example, natural selection it would
be possible, I think, to show how research activities were generated in
and genetics that definitely increased our knowledge of biological systems.
These insights serve as empirical examples of scientific progress, so
whether or not one might ascribe to the creed that natural selection is
the primary "mechanism" of evolution, it is still possible to specify the
untility of the concept as a research tool. The same might apply to the
multitude of other evolutionary concepts such as concerted evolution,
epigenesis, development, not to mention good old biogeography - which
started Darwin down this tricky, but interesting, road in the first place.
