WebJun 8, 2024 · Figure 23.1 C. 1: Endosymbiosis: Modern eukaryotic cells evolved from more primitive cells that engulfed bacteria with useful properties, such as energy production. Combined, the once-independent organisms flourished and evolved into a single organism. Endosymbiotic Theory WebWe expect that detailed experimental studies of individual virus–host systems will reveal a wide range of functions for these variable and abundant eukaryotic EVEs. Taken together, our findings provide an exciting perspective into the intricate and complex virus–host arms races that have shaped evolution across the eukaryotic tree of life.
