“Language is a virus from outer space.”
Quiz time, what is a genetic phenomenon believed to be caused by (perhaps endogenous) retro viruses?
Those viruses leave inheritable markers on your genome in unique locations with unique characteristics. If your great grandfather got the virus the market will be on your genome and on the genome of your ten thousands grandson.
All humans and all chimpanzees have similar markers from an evolutionary ancestor that was neither human nor chimpanzee. We, both species, are all descendent from an earlier species. Modern genetics would be invalidated were it otherwise.
It means absolutely zero to me if you want to believe in some other idea written by people who didn’t know the earth orbited the sun and the blood circulated in the body.
