I'd assume it's due to the discovery not being some human remains but rather processed wood, making it the oldest evidence for wood working we have by a massive margin. Quote from the article:

> Prior to this discovery, the oldest known surviving wooden structures were built by people living in northern England around 11,000 years ago.

I get that. I just thought there were a tonne of even more exotic finds of more advanced technology than woodworking — but it’s not always clear which are ‘fringe’ and which have been invested with the epistemic authority of institutional science. That is the confusing thing.
