Eusociality evolved repeatedly in different orders of animals, particularly the . If a queen is lifetime-strictly monogamous – in other words, she mates with only one individual during her entire life – her progeny will be. Focusing on lifetime monogamy as a universal precondition for the evolution of obligate eusociality simplifies the theory and may help to resolve controversies.

Hamilton proposed that eusociality arose in social Hymenoptera by kin selection because of their interesting genetic sex determination trait of haplodiploidy.

Seeley 54 Estimated H-index: The monogamy hypothesis, formulated by Jacobus Boomsma inis currently the leading hypothesis concerning the initial evolution of eusociality in the Hymenoptera.

Innate social aptitudes of man: The separation of sexual activity and reproduction in human social evolution. This hypothesis also mimics the effects of haplodiploidy, but proposes that males would help raise only the queen’s male offspring, while females would only care for the queen’s female offspring.

Thus, sisters will propagate moonogamy own genes more by helping their mothers to raise fhe sisters, than to leave the nest and raise their own daughters.

eusociakity The monogamy window can be conceptualized as a singularity comparable with the single zygote commitment of gametes in eukaryotes. The monogamy window underlines that cooperative breeding and eusociality are different domains of social evolution, characterized by different sectors of parameter space for Hamilton’s rule.

This seems to be the ancestral state in all Hymenopteran lineages that have evolved eusociality. Hamilton[3] or by the competing theory of multilevel selection as proposed by E.
