„Without the LTR5Hs, the middle layer (epiblast) of the three-tissue-layered blastoid did not form properly.“
This is the sort of thing that lends support to ‚viruses not alive‘ theory, seems more correct to assume that viruses independently arise from stray internal RNA delivery mechanisms of several different eukaryotes than exist as protoforms of much older life:
„Up to **9 percent of our DNA is composed of genetic material from ancient viral invaders.** These [endogenous retrovirus](https://en.wikipedia.org/wiki/Endogenous_retrovirus) remnants infiltrated the genetic material of our ancestors‘ reproductive cells millions of years ago and are now permanently integrated into our genetic blueprints.
LTR5Hs **appeared in our ancestral line around 5 million years ago, after humans and other great apes had parted ways with ‚old world‘ monkeys** such as baboons and macaques.“
Seems unlikely that all of these changes were virus-driven. Betting we find that new ‚viruses‘ or viroids can independently form from the remnants of dead or rotting tissue based on how the complex systems break down.
