After reading a number of books by Dr. F. Collins, Dr. D. Venema, Dr. J. Swamaidass as well as looking at numerous articles and videos from BioLogos, on ERVs as evidence of common descent, there are some questions that remain open:
My understanding is that most primates share some ERVs at the same loci in genome. This is used as strong evidence of common descent.
Questions about this:
- Is my assumption correct that all humans and all Chimpanzees share some ERVs at the similar loci in the genome?
- When a RV infection occurs in a species, I assume it occurs in a subset of the species population as a whole. In other words, it is impossible for the entire species to get the same RV in the same loci at the same time. Is this correct?
- My understanding is that some ERVs are shared by all humans and all Chimpanzees. How does a ERV propagate to an entire population of a species?
