Female-led infanticide in wild chimpanzees

Researchers observing wild chimpanzees in Uganda have discovered repeated instances of a mysterious and poorly understood behavior: female-led infanticide. The findings, reported by Simon Townsend, Katie Slocombe and colleagues of the University of St. Andrews, Scotland, and t...
