You evolutionists have lost this round lovies. The reason being to argue about the intricacies of this nonsense is based on ridiculous and non-credible algorithms that count or ignore whatever they need to, swish that with a stack of predetermined assumptions and insertion values placed on misrepresented fossil evidence, throw in a bottleneck or two and a heap of likely, maybes and possiblies and whallah...you have nonsense mutations and nonsense data that mean absolutely nothing as far as evidence goes.
Without using one person as a 'whipping boy' here, I think there is a little misunderstanding surrounding ERV's here.
If a virus inserted its DNA into your germ cells (ie sperm or eggs) you would not be infected (that would require somatic cells to be infected), but the DNA could potentially pass to your offspring (if the infected germ cell was fertilised and so on).
In your offspring, this 'new' genetic material would sit neatly in the genome, and each succesive offspring would receive a copy also.
Any children you had earlier would not have this viral DNA.
All conceived afterwards would.
This is not common descent, this is not evolution, this is an observable fact - descent with modification.
Fast forward 100 generations, and any direct relatives of the earlier children would not have these viral DNA sequences in their genomes if they havn't reproduced with anyone that does (ie they have become a seperate population by emigration, perhaps), and those from later born will have.
If the DNa is not for a gene (ie it is redundant) then it is free to mutate/translocate/be copied multiple times or whatever in the genome with no ill effects to the animal.
The less the viral DNA insert looks like the original, the longer it has had to mutate -providing it can still be seen to be 'homologous', that is similar enough to the original insert to be recognisable, as opposed to so dissimilar it could have occured by random chance (ie another insetion)
What is being discussed here is that we have found our genome to be littered with ERV's. The vast majority of these are homologous with chimps, slightly less with the other apes, and even less with other mammals.
Given this fact on its own, I would bet a suprisingly large amount of money that they would be homologous with
H. neanderthalis DNA.
What conclusions can we draw from this?
Common descent is the only sensible conclusion.
Like it or not, it is a fact that the evidence displays in great big letters (that would be CTGA then).
There is no debate here, there is no cover up or clever mathematical guesswork.
Our DNA is very similar to
P. troglodytes for the same reason that your DNA is very similar to your cousins.
