- A. It decreases communication efficiency
- B. It enables the transmission of complex cooperative strategies ✓
- C. It has no effect on cooperation

Knowledge check
Q1. What is a common reason for cooperation among animals in the wild?
- A. To increase individual survival chances
- B. To increase group survival chances ✓
- C. To reduce competition
