Animal polyembryony appears to be paradoxical because it clones an unproven genotype at the expense of genetic diversity in a clutch. However, it is employed by at least 18 taxa in six phyla (excluding instances of occasional twinning). Most polyembryony occurs in parasitic stages or in other environments whose quality is not predictable by the mother; in some instances, it compensates for a constraint on zygote number. We predict that polyembryony is likely to evolve when the offspring has more information regarding optimal clutch size than the parents.
