					<description><![CDATA[In a groundbreaking study that reshapes our understanding of early eukaryotic evolution, researchers have rigorously analyzed the ancestral stem lengths of core eukaryotic genes to gain fresh insights into the timing and origins of mitochondrial acquisition. This approach revisits and extends the methodology first proposed by Pittis and Gabaldon, who postulated that the relative lengths [&#8230;]]]></description>
