Agreed and yes I read that book ✅.
My point is that I don't think DNA is much more than a determinant of what proteins can get made. It dues not contain information on morphology etc etc... AND it can morph into entirely different DNA in certain conditions. Inheritance is mostly resonance (morphic fields, ...).
So that's why I'm weary of calculations that use genes as some kind of proof for things like family trees, especially in time periods with violent changes in magnetic + other fields 😅
