I don't even disagree that it's a fine headline, but this community shits its pants everytime an article isn't extremely accurate in it's headline, so it's funny to suddenly have an army of people descent upon this comment section to defend specifically this one.

This study does not concern itself with iron age populations in general but specifically celtic communities between 100 BC and 100 AD in Britain.
