In 2009, Jacobus Boomsma (“YAK-OH-bus BOOM-smuh”) theorized that the evolution of this behavior typically occurs once a “monogamy window” is reached. A criticized 2010 study by Nowak et al. suggested that this behavior evolved in a five-stage process that concludes with multilevel selection. Sponge-rich territories are protected in one form of this behavior exhibited by Synalpheus (“SIN-al-fee-us”) shrimps, known as fortress defense. In one theory, taxa predisposed to this behavior have their males and females develop from (*) unfertilized and fertilized eggs, respectively. The only mammals (10[1])to exhibit this behavior, (10[1])once (10[1])popularly explained via the (-5[1])haplodiploid (“HAP-loe-DIP-loid”) hypothesis, are the Damara and naked mole rats. (10[1])For 10 points, name this altruistic behavior (-5[1])in which non-reproductive individuals help care for the young, observed in wasps (-5[2])and bees. ■END■ (10[2]0[2])
