I can't find in any of the linked sources any conclusive proof that all children are born with perfect pitch. From my own research in 2011, I hadn't discovered any papers which would make so bold of a conclusion. This proposal[0] linked by the article mentions a few studies that show some environmental factors that seem to have a high correlation to absolute pitch, such as growing up around tonal languages, but nothing conclusive about absolute pitch just being a thing that we all have but that most of us lose. There are correlations to age groups, ethnic backgrounds, linguistic backgrounds, and musical backgrounds, but again most studies have looked at the environment for clues about how absolute pitch works as opposed to presenting evidence of something innate. Musical cognition is an absolutely fascinating field of study, and it absolutely plays a critical role in the way humans function. However, I think this article is a little click-bait-y, seemingly drawing an unfounded, fantastical conclusion about a particularly popular aspect of the field. As far as I can tell, it's completely unsubstantiated. [0] http://www.auditory.org/mhonarc/2004/save/pdf00001.pdf http://www.auditory.org/mhonarc/2004/save/pdf00001.pdf Edit: words are hard
