It is almost as if some junior editor (or LLM, though I think this practice predates them) has been given the job of dividing the article into sections with headers, but can't be trusted to use their own words for the headers (though they can still, of course, both divide and quote out of context.) Here, this appears to have been applied after someone else (the author, perhaps?) had already divided it into sections with traditional summaries for headers.

That said, I felt this article is much more engaging than the average university press release, and presents a genuinely significant discovery without, as far as I can tell, another now-commonplace annoyance: the excessive exaggeration or misrepresentation of that significance (though one might quibble over "...and could rewrite our timeline of complex life on Earth altogether.")
