Original sentence: After phagocytosis, macrophages and dendritic cells can also participate in antigen presentation: this is when the phagocyte moves parts of the ingested material back to its surface.However, many pathogens have evolved methods to counter attacks by phagocytes.Phagocytes occur in many species; some amoebae behave like macrophages which suggests that phagocytes appeared early in the evolution of life
