W. D. Hamilton famously suggested that the inflated relatedness of full
sisters under haplodiploidy explains why all workers in the social
hymenoptera are female. This suggestion has not stood up to further
theoretical scrutiny and is not empirically supported. Rather, it appears
that altruistic sib-rearing in the social hymenoptera is performed
exclusively by females because this behaviour has its origins in parental
care, which was performed exclusively by females in the ancestors of this
insect group. However, haplodiploidy might still explain the sex of
workers if this mode of inheritance has itself been responsible for the
rarity of paternal care in this group. Here, we perform a theoretical kin
selection analysis to investigate the evolution of paternal care in
diploid and haplodiploid populations. We find that haplodiploidy may
either inhibit or promote paternal care depending on model assumptions,
but that under the most plausible scenarios it promotes – rather than
inhibits – paternal care. Our analysis casts further doubt upon there
being a causal link between haplodiploidy and eusociality.
