This study examines how aging affects nut-cracking behavior in wild chimpanzees, finding age-related declines in engagement and efficiency with individual variability.

This study examines how social learning experiences during early development affect technological efficiency in wild chimpanzees, finding that more social learning opportunities and tolerance correlate with greater efficiency.

The paper compares nut-cracking techniques and tool modification in chimpanzees, capuchins, and macaques to understand how tool skill affects archaeological evidence.

This study investigates long-term individual variation in chimpanzee nut-cracking efficiency over 25 years, finding stable differences that challenge previous sex-based conclusions.
