Phagotrophy describes the process by which unicellular organisms derive their food from engulfing and digesting other cells (Fig. 1). The process is thought to be ancient, but establishing exactly when phagotrophy emerged in the history of life is difficult and a source of ongoing debate. Opinions range from very early origins to a relatively late emergence in the evolution of life, well after the appearance of fully formed eukaryote cells (that is, cells with a nucleus and mitochondria).
