Virus-host arms race at the joint origin of multicellularity and programmed cell death

Abstract excerpt

Unicellular eukaryotes and most prokaryotes possess distinct mechanisms of programmed cell death (PCD). How an "altruistic" trait, such as PCD, could evolve in unicellular organisms? To address this question, we developed a mathematical model of the virus-host co-evolution that involves interaction between immunity, PCD and cellular aggregation. Analysis of the parameter space of this model shows that under high...
