In 2009, Jacobus Boomsma (“YAK-OH-bus BOOM-smuh”) theorized that this behavior will more likely to be evolved 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 (-5[1])defense. In one theory, taxa predisposed to this behavior have their males and females develop from (15[1])(*) unfertilized and fertilized eggs, respectively. The only mammals to exhibit this behavior, once popularly explained via the haplodiploid (“HAP-loe-DIP-loid”) hypothesis, are the Damara (“dah-MAH-rah”) and naked mole rats. (10[2])For 10 points, name this (10[1])altruistic behavior in which non-reproductive individuals help care for the young, observed in wasps and bees. ■END■ (10[1])
