You might want to look up what ERV's are. They are not "design elements". They are remnants of infections.
You just called your god a liar. You just said that your god planted fake evidence of infections that never occurred.
This would be the equivalent of creating a human with a scar of a shark attack that never occurred.
On top of that, not only did he, in your apologetic opinion, plant such fake evidence in all species... he even went out of his way to do it in such a pattern that it is completely consistent with common ancestry....
If an infection inserts itself in the genome of a host, creating an ERV, then this gets past on to its off spring, resulting in an identical ERV in that lineage.
As
@Subduction Zone told you so many times already, you are calling your god a liar. Stuff like this is what he means.
But I'm sure you'll stick your head in the sand again.
Only if their goal is to deceive people.
Also, insofar as the reuse of parts occurs in engineering, those commonalities NEVER result in nested hierarchies. That is incredibly wasteful and inefficient. Any engineer designing product lines like that would be fired instantly for incompetence.
Genomic analyses show that two independent fusions involving the same chromosome altered recombination patterns and contributed to reproductive isolation between two Pristionchus nematodes.
