Disputed The sentence appears in the cited PMC article essentially verbatim; the PMC snippet shows the submitted wording, and an accessible PDF copy shows the same sentence with the compound adjective rendered as as-yet-undetermined. But the source is a multi-author Science paper credited to Jonathan E. Pekar and many coauthors, with Katherine Izhikevich listed as only one coauthor, not the sole quoted author. Under this platform's rules, a multi-author paper cannot be verified as a single-author quote, so the attribution is disputed.
