DAVID: We don't know how far epigenetic changes can/will make new species, since we don't know how new species are created. We've had this discussion before about inventive mechanisms, with no conclusion except there might exist like it.

> dhw: That is what I call progress. I have fought long and hard for the concession that this hypothesis is possible! Since none of the facts are known, only the faithful can draw clear conclusions.-I don't view it as progress, because we had a long discussion in which both of us discussed the possibility. Certainly a possibility as we keep opening up layers of DNA control and expression, there might be a speciation layer pre-programmed to allow for giant leaps in phenotypes.
