Question

Quizplus · Accepted Answer

Dispersing with peers or joining all-male groups can help males reduce the cost of dispersal as they can share the responsibilities of finding food and avoiding predators, and also get social support from their companions. Dispersing alone or far from their natal group would increase the risk of predation, unfamiliarity with the new habitat, and competition for resources, and hence would incur a high cost of dispersal. Dispersing at night close to other groups might not necessarily reduce the cost of dispersal as males still need to sustain themselves and avoid predators during the day. Therefore, option A is the best choice.
