Didn't Zing Yang Kuo do some work on this in the 50s-60s? As I recall, his topic, maybe a book or a major article, was the "epigenetics of development." Again, as I recall, he offered an explanation for the fact that pigeons bob their heads when they walk. The work you describe sounds like it could be a fascinating extension of Kuo's research. DKH

If you haven't heard of it before, epigenetics is a scientific discipline that has been emerging over the past decade or so that attempts to model the regulation of gene expression -- i.e., of the many genes in an organism's DNA, many are never expressed, and apparently identical genes in two different organisms of the same species can be expressed in different ways and at different times. Environmental factors seem to control which genes are expressed and the manner in which they are expressed. How precisely this works is what the field of epigenetics attempts to address. One can get access to the article at http://www.nature.com/nrn/journal/v8/n5/index.html (though one has to register on the Nature site to get it). Regards, Chris Green York U.
