Genes can exert influence on development of structure without containing
some sort of homuncular "blueprint".

I have in mind that Darwin put forth a shaky speculation about particles
from various modified parts of the body (gemmules) somewhow influencing the
gonadal structure and allowing for acquired traits to be passed to
offspring. Was he aware of Weismann's doctrine of the germ-plasm?
IIRC Gregory Bateson considered Lamarck a great biologist who turned a trick
similar to the Copernican revolution in that L. inverted our views of mind
versus biology. Before Lamarck it was Mind first from on high. After Lamarck
the mind emerged from the realm of biology itself. Lamarck was also a
pioneer of comparative psychology, however crude his attempts by our
