OK - I don't have much background with ERV nor shared DNA errors but is it possible that these could be attributed to shared living conditions? Is their only one way for these shared errors and gentic markers to appear in DNA?
That'w why I specifically mentioned the Asian vs African apes, and the Old and New World monkeys. Different food, parasites, diseases, predators, etc.
The pattern of genetic markers tracks the independently-established phylogeny, not geography.
