					<description><![CDATA[The emergence of oxygenic photosynthesis marks one of the most transformative chapters in Earth’s history, fundamentally reshaping the planet’s atmosphere and biosphere. Yet, despite its undeniable significance, the precise timing of when this biochemical innovation first arose remains fiercely debated among scientists. Recent research presented by Patry et al. pushes the boundaries of this inquiry, [&#8230;]]]></description>
