As I said that the Darwinian model for the TOE may well still be the valid basis for change. But this does put a question mark over at least how much it influence change. If HGT is a fair amount of the reason or is a bigger contributor to spreading genes between creatures then it muddies the waters.
It doesn't muddy the waters at all. Viral insertions are lineage specific and can be used to construct phylogenies. They are no different than any other random mutation.
You cant then stand firmly on darwinian evolution through natural selection and common decent being the only driving force that created new creatures from a random and chance process of mutations adding new genetics to a creature.
Yes, you can. Viral integrations are random with respect to fitness, exactly what the theory of evolution states. Those random, and lineage specific, changes are then passed through natural selection. As seen from a comparison of the genomes of humans and other apes, the lineage specific viral insertions and other integration events produce the expected nested hierarchy.
If the junk DNA has a role to play . . .
If junk DNA plays a role, then why is it accumulating mutations at a rate consistent with neutral drift?
Thus, according to the ENCODE Consortium, a biological function can be maintained indefinitely without selection, which implies that at least 80 − 10 = 70% of the genome is perfectly invulnerable to deleterious mutations, either because no mutation can ever occur in these functional regions, or because no mutation in these regions can ever be deleterious. This absurd conclusion was reached through various means, . . .

I suggest you read the rest of the abstract, at least.
What you need to explain is how junk DNA can maintain function no matter how much you change the actual DNA sequence.
then there is a whole lot more genetic ability that can be tapped into for adding new features to creatures. For all we know all the genetics of the basic features or a greater deal than we think of every creature may well already be within every creatures genetic makeup sitting there waiting to be used when needed. I am not a geneticists and this is my observation. It may be to simple but I suspect there is some truth to it.
Again, you are ignoring the basic fact that species are different from each other because the sequence of their genomes is different.
