Why is the origin of termite eusociality more difficult to understand than the origin of hymenoptera eusociality?
a. Termites have a XX/xY sex determination system. This means that there is no added kin selection benefit to to an increased degree of relatedness.
b. Ants benefit from cooperation among individuals in the colony, however there appears to be no net benefit for cooperation among termite workers.
c. Termites eat wood and so have a complex set of endosymbionts that help them digest cellulose. This means that eusociality is much less likely.
d. Because termited can have multiple queens in each colony, but the Hymenoptera only have one queen
