You're quote mining again. You didn't even bother to read your own posted article. This reminds me of the time you tried to compare a clay pot full of sulphuric acid to a computer monitor.

You said,

This is a very big change, something out of nothing, something which changed humans a great deal. It is a large jump totally unexplainable by evolution.

A couple paragraphs further in the article, we read.

Finding real evidence for sudden genetic changes, however, has been slow. By using phylogenetic surveys, however, McDonald and King were able to distinguish between the youngest HERVs (human endogenous retroviruses) and more ancient lineages

In other words, further evidence that HERVs evolved from older retroviruses.

And no fair posting more comments before I can work my through this page.

Nope, you have a reading comprehension problem. They were able to separate the new from the old by comparing the whole bunch to those that were found in other species. That's how "The discovery that human-specific retroviruses emerged at the same time other researchers believe humans and chimps diverged was startling" came about. As noted for this happen all of a sudden, all of them working together, is unexplainable by evolution.
