Maybe i missed some words in the article, but I don't see it say when they figured this out. Because it's been at least a decade since I learned about it in school or from a science magazine at school.

Have people been going around not knowing about this until now?

Or is it that only now can they say with certainty this is true?

yeah I thought we (humanity) already knew this and for some time now.

I think humanity has always assumed this. Hurray for scientific conformation.
