When a Beowulfan geneticist says that he will “work right up to the limit” of the basic genetic material, what this specifically means is that he will not introduce nonhuman or synthetic genetic material and that he eschews any deliberate effort to produce Homo superior.

The Beowulf code is entirely prepared for genetic modification to deal with recognized disease states, and within the limits of the donor genetic material which is combined to create a human being, the Beowulf code is prepared to allow the parents to mitigate what they — the parents — see as undesirable characteristics and to enhance what they — the parents — see as desirable characteristics.
I’m not exactly clear how this works, or if it is internally coherent.
Firstly, what ‘donor genetic material’ are we talking about? Stuff within the genome of the parents? Or any stuff some kind person happens to have donated and the geneticist has lying around his lab? If it’s the former I can’t have ginger hair if neither of my parents has the genes for it, and probably lots of other more serious restrictions if my parents ’genetic potential’ (however you define that) happens to be limited. Presumably, however, it is the latter. How else do you quickly produce a colony sized group with e.g. the ‘Meyerdahl enhancements’? So the Beowulfans probably are prepared to splice in genes that have nothing to do with my genetic parents (or main genetic parents, if you like.).
Secondly, since the aforementioned Meyerdahl enhancements always breed true, even from one enhanced parent, the Beowulfans are also prepared to make actual changes to the structure of the genome, since no natural traits are expressed in that way, so far as I know. How far can you change the genome in the lab and not be using ‘synthetic genetic material’?
Thirdly, given the degree of mutation that you are going to get in a multi-billion person human race does the objection to synthetic genetic material really make sense? If I can pull a mutated gene which occurred naturally in someone, somewhere, out of a sample, that’s OK to use. If I whip up the same gene in a lab out of my head before the sample is known about, that’s forbidden. Isn’t this verging on a distinction without a difference? Or how would you make it work coherently?
