Question on Retroviruses and Evolution

This is an important question to me.

According to this source, we share 7.
29+ Evidences for Macroevolution: Part 4

According to the below source we share 16 class-K ERV's alone.
Online Debate: Resolved: Endogenous Retroviruses (ERVs) confirm common ancestry (evidence for evolution) | Debate.org

I could not find any estimates of the total number of ERV's, only class K.

I am also wondering whether these ERV matches are really in the exact same position or have the exact same sequence. I could not find that out.

I don't know if there is an exact number, but we have thousands of ERVs in our genome.

Depending on when each piece was written, the number of ERVs known to match could easily go up as we have finished both the human and chimpanzee genome projects.

As for the matches... yes, they are in the same "exact" position and have the exact same sequence.
(When I say "exact" in terms of position I mean they are inserted into the same gene clusters and that most of these are in the same places on chromosomes... but given that humans have a fused chromosome pair and a couple of transposed genes what is considered "exact" position wise may not always be what you might think of as "exact"... though that also makes them useful as an additional way to measure how long we have been evolving away from each other)

You can repeat this comparison with LINES and SINES (the other two types of viral DNA inserts).

I found a pretty good link about that.
