Then why have one set of virial DNA incorporated into the non-coding DNA of gorillas, chimps, and humans and another set of viral DNA incorporated into the non-coding DNA of chimps and humans, each in the same place in the genome?

The above is the equivalent of an evolutionist "urban legend". It's just plain is not true at all. Neither chimps nor humans can produce vitamin c. However, the devil is in the details:

It is interesting to note that most animals produce their own vitamin C. Man, primates (apes, chimps, etc.) and guinea pigs have lost this ability.

Hmm, your sources did not mention the guinea pigs did they? Guess man and chimp descended from guinea pigs? Are guinea pigs the missing link? Seems evo 'scientists' are very selective. They only 'remember' what serves their purposes. But wait, it gets better:

Actually, the LGGLO pseudogene (an inactivated Vitamin C synthesis gene) has been found in one human so far and no apes, according to Edward Max, but in his essay he predicts that it should be found in apes, too.

So, it seems someone claims that this is not true, and cites an evolutionist as saying that this claim is an assumption not fact. So while to me, this might be credible enough, to you an assertion by a Christian alone would not be. So, we must dig a little deeper:

if primates closely related to humans have the SAME crippling mutations in their LGGLO pseudogenes as we see in the human pseudogenes, this finding would support the evolutionary model. As I pointed out, the data on this question are not yet available for the LGGLO pseudogenes, but in other shared pseudogenes identical crippling mutations clearly favor evolution
From: Response to Plaisted

So it seems that the evolutionists have been found lying again (and by this I do not mean you or anyone else here - this garbage is all over the internet). Max in his original article, while not outright saying that men and chimps shared the exact same mutation in the exact same pseudogene went into a long and very contrived discussion which to most laymen would indicate that such was a proven fact. In other words, he clearly was trying to deceive and clearly deceived many. (the original article is here ). So much for vitamin c. Another evolutionist snow job disproven.

BTW this whole nonsense started - as usual - in that fountain of evolutionist disinformation - TalkOrigins

You are again failing to read what I wrote. The guinea pig (which I mentioned as "other") doesn't have the same mutation as chimps and people. Chimps and people have the exact same mutation.

While chimps, people, and guinea pigs all have a similar phenotype (not able to make vitamin C), only chimps and humans have the exact same genotype for this defect.

There are other similar markers in the literature. You can read about them in PNAS or Cladistics.

Can you point out to me where Max makes this statement? Thanks.
