Yeah I don’t like big numbers. As a physicist I generally tend to believe they are indicative of a model not accurately describing reality. None the less, I’m almost sorry you watched that video. I started to post to ask you to stop but you did none the less. So thanks for that.
By evolution you mean common descent?
That’s silly, did the video say that? They certainly don’t have to be non-functional, with ~7% of the human genome being made up of such ERVs. Here’s a paper demonstrating how some ERV insertions helped the development of the placenta:
Retroviruses facilitate the rapid evolution of the mammalian placenta
The non-functional thing was brought up several times in the thread, along with several EN articles but it’s a lot to just toss your way, I was surprised you even looked at the video in the OP…
