Regulation is the important thing, it's what creates
diverse organisms from a common ancient skeletal pattern,
which is simple in form and is only known by extrapolation
from the pattern of reduction and distortion among parts.
Regulation of the ontogeny of this original form is what
sculpts organisms.

What is doing the regulating? An unlimited variety of
opportunistic mechanisms, I would think. I just speak
for the necessity of recognizing that there is a something
whose ontogeny is regulated, a something distinct from
regulation itself.
