Final answer:
Eusocial systems are more likely to evolve in species with low genetic diversity because genetic diversity is the raw material for adaptation in a species, allowing for a greater range of traits and adaptations.
Step-by-step explanation:
Eusocial systems are more likely to evolve in species that have b. Low genetic diversity. Genetic diversity is the raw material for adaptation in a species, and a species' future potential for adaptation depends on the genetic diversity held in the genomes of the individuals. Higher genetic diversity allows for a greater range of traits and adaptations, which can be beneficial in the development and maintenance of eusocial systems.
