I am assuming that nested hierarchy is identifying the sequences in one creature that are duplicated in a “higher” one. For it to be “Nested” then, I would assume that all the sequences of the first creature are present in the second? If not how is it completely nested?
But, if the method of development is to adjust deform or mutate how can you identify which sequences are genuine and which ones have been deformed? If the complete sequences are all present then there has been no deformation
And,if you have not decoded DNA, how can you be certain that you have the right length of sequence? Or that all the sequences are of the same length? Where one sequence starts and another stops? And, of course, what any particular sequence represents in terms of structure or form?
How can you compare 2 sets of code if you cannot catagorise and decode either of them?
(This is not antagonistic. This is an attempt to understand. Feel free to laugh and mock, I am used to it)
