Junk DNA Mechanism That Prevents Two Species From Reproducing Discovered


Junk DNA Mechanism That Prevents Two Species From Reproducing Discovered.

“…The segment of DNA was found in the chromosome’s heterochromatin, a densely packed region of highly repetitive sequences of junk DNA near the chromosome’s center.
During the embryo’s initial divisions, the researchers found, a specific segment of heterochromatin gets “sticky” and halts the process, preventing the entire X chromosome from separating properly; the result is that the early embryo dies…”

I wonder whether this same mechanism was involved in hominin speciation events…May be some HERVs, considered junk DNA, were involved??
