Hieroglyphs, petroglyphs (pictures carved into rocks), and cuneiform (a writing system using hashmarks on clay tablets) were all early forms of written communication. All of them were precursors to alphabets, which use letters to represent sounds. Grunts are an early (and present-day) form of communication, but they aren't written.

The answer is Chronologically because the author is giving on the beginning the timeline that narrates everything about Gertrude Belle Elion.
