Thanks for sharing George. I hadn’t come across the ERV evidence for common ancestry before @T_aquaticus posted back in August of last year: ERV evidence for pastor with a lawyer's mind - #18 by T_aquaticus
Just from ERVs you can construct phylogenies that mirror just that of other methods of organizing ‘species.’ I think the probability estimates in the video are a little high (but the overall probability is much higher) because ERVs can have selective site preferences, which as @T_aquaticus notes in the post just above moves the probability from 1 in 3 billion to about 1 in 10 million per ERV insertion location. However, instead of just 16 ERVs, we are looking at much much more than this in reality…
Humans have approximately 200,000 ERVs and we share 99.9%+ of all of them with chimps so now our probability goes to:
1 in (10,000,000)^200,000 or 1 in 10^1,600,000 making even the most irreducibly complex system/protein folding look like a cakewalk!!
