My gripe is not that there is some convergent etymology, it's attributing it to genetics. I think a phycist would feel similarly if it was attributed to "human energy" or something like that. Sure almost all languages share consonants, but there are only so many sounds our mouths can make that has nothing surprising. Yet there are exceptions like Dahalo which is a language made of clicks. Sure there are similar words from different roots. Say in the 3 languages I speak, mom/maman/mama, dad/papa/tata, no/non/ne. But there's no reason to involve genetics. Some sounds are easier to make for babies/toddlers, it makes sense they would converge toward for universal words like parent appellations. Protein synthesis doesn't have to play a part in it no matter how magical genetics may seem.
