Question

understand: evolution of group behavior
which of the following are likely benefits of group behavior?
choose 2 answers:
a a decreased likelihood of sickness and disease within the group
b a higher likelihood of survival for individuals in the group
c a higher likelihood of survival for the group as a whole

Explanation:

• Option A: Group behavior doesn't inherently decrease sickness/disease likelihood; in fact, close contact in groups can increase disease spread, so A is incorrect.
• Option B: Groups can provide protection, resources, and support, increasing individual survival chances (e.g., hunting in groups, defense from predators), so B is correct.
• Option C: Groups can work together for survival (e.g., finding food, defending territory), increasing the group's overall survival likelihood, so C is correct.

Answer:

B. a higher likelihood of survival for individuals in the group
C. a higher likelihood of survival for the group as a whole
