What kind of propagating waves do you have in mind? We've found a set of
solitary waves in one to one correspondence with steps of determination
in amphibian embryos, up to neural tube closure, that may be implicated
in further regionalization of the CNS (see below). We speculate that
wave-wave interactions may be responsible for the independence of
development on temperature: one wave must finish and perhaps set up the
conditions necessary to initiate the next.

I am finishing a book about the intersection of three major fields of
Gordon, R. (1995). The Hierarchical Genome and Differentiation Waves:
Novel Unification of Development, Genetics, and Evolution (Singapore:
World Scientific), in prep.
If your work might be relevant to this review, I would appreciate reprints
or preprints as soon as possible, or an update, if I've been in contact
with you previously.
Thanks for your help. Please be sure to send your e-mail address,
in case I have any questions.
Best regards, -Dick Gordon
