Oops, I just saw that you already answered my question the first time around. So we apparently share all but 82 of our 203,000 ERVs with chimpanzees. That’s pretty amazing evidence for common ancestry.
Are you sure that that’s the total amount, though? They only looked at the aligned parts of the genome, what about the indels between humans and chimps which account for like 3% of the differences, so maybe there are more that are hidden? Even if that’s the case, there’s literally zero chance of separate ancestry given this huge amount of shared ERVs.
Edit: Just as an interesting aside, if we input 203000 total ERVs, 202918 (203000 - 82) shared ERVs, and a 0.0000001 chance of two ERVs randomly inserting in the same place, the binomial distribution calculator here gives a probability of… drumroll please… 1.691 * 10^-1,419,228. Yes, you read that correctly. The chance of this many shared ERVs, if common ancestry is false, is less than 1 in 10^1 million.
