    >>According to the standard view, the development of an embryo is
    programmed by its genes-its DNA. Change the genes, and you can change the
    embryo, even to the point of making a new species. In the movie "Jurassic
    Park," genetic engineers extract fragments of dinosaur DNA from fossilized
    mosquitoes, splice them together with DNA from living frogs, then inject
    the combination into ostrich eggs which had had their own DNA inactivated.
    In the movie, the injected DNA then re- programmed the ostrich to produce a
    dinosaur. Experiments similar to this have actually been performed, though
    not with dinosaur DNA.
    >>In every case, if any development occurred at all it followed the pattern
    of the egg, not the injected foreign DNA. While I was at Berkeley I
    performed experiments on frog embryos. My experiments focused on a
    reorganization of the egg cytoplasm after fertilization which causes the
    embryo to elongate into a tadpole; if I blocked the reorganization, the
    result was a ball of belly cells; if I induced a second reorganization
    after the first, I could produce a two-headed tadpole. Yet this
    reorganization had nothing to do with the egg's DNA, and proceeded quite
    well even in its absence (though the embryo eventually needed its DNA to
    supply it with additional proteins).

    Wells is actually correct though I think this is another case of trumpeting
    something that isn't that big of a deal. He trumpets the standard view
    and then acts as if this is some new insight. Yes the development of the
    first cells divisisions has more to do with the preprogrammed materials
    that were supplied by the mother than they do with the actual DNA of the
    embryo. This is why some characteristics of a mother can be imprinted on
    her progeny even if they don't share her DNA. I don't think there is much
    her to fight the Darwinists on. Joel
