Despite extensive evidence of virus-virus interactions, not much is known about their biological significance. Importantly, virus-virus interactions could have evolved as a form of cooperation or simply be a by-product of other processes. Here, we review anddiscuss different types of virus-virus interactions from the point of view of social evolution, which provides a well-establishedframework for interpreting thefitness costs and benefits of such traits. We also classify interactions according to theirmechanisms of action and speculate on their evolutionary implications. As in any other biological system, the evolutionarystability of viral cooperation critically requires cheaters to be excluded from cooperative interactions. We discuss how cheaterviruses exploit cooperative traits and how viral populations are able to counteract this maladaptive process. |
