Social Structure and Information Transfer in Elephant Matriarchies
Quick fact
Elephant herds are led by a matriarch, usually the oldest and largest female, whose decades of experience and social memory can mean the difference between life and death during droughts, as she recalls distant waterholes and safe migration routes.
Why this is interesting
Imagine a family where the grandmother's memory holds the key to survival—not just for her, but for her entire clan. In elephant herds, the oldest female's knowledge literally guides the group through droughts, dangers, and daily life.
