Fun thing is while my post was written with a "I'm not sure about this article" mindset it kinda supports the article. I mean what is convergent evolution in context of an single species? Wouldn't it be pretty much genetic variances of multiple people which are unrelated randomly converging by chance? Sure with convergent evolution in nature you still don't necessary have DNA similarities, but there the DNA also largely diverged to a point of it being different species before converging. For humans the DNA was always similar so the simplest (i.e. most likely) way would to reach the same "looking" outcome would be by having the same changes/mixing of DNA variations.
