Follow the Leader!

Americans will choose government leaders this month. That includes the president. These elected leaders make decisions. Those choices affect the country’s people. There are leaders outside government too. Your school’s principal is a leader. The coach of a sports team is also a leader.  

But leaders don’t just exist in our society. All kinds of animals live in groups, from bees to elephants. Group life can help these creatures. It allows them to better defend against predators. They can hunt together and share food. Sometimes, group members weigh in on decisions (see Group Decisions, below). Other times, leaders call the shots, such as where travel to find food.

Scientists have been studying animal leadership for a long time. Their research sheds light on how human societies evolved. That helps scientists learn more about how groups of people make decisions today. “It’s interesting to see the different ways that animals solve the same problem,” says Robin Morrison. She’s a scientist. She works at the Dian Fossey Gorilla Fund in Rwanda. 

Scientists study animal leadership by watching groups in the wild. The scientists trek into the animals’ natural habitat. They watch how a group’s members behave. Sometimes, they even fit the animals with devices. They track where the animals go. Scientists have found that leaders have special skills. These traits help their groups survive. 

For many creatures’ leaders, knowledge matters most. African elephants live in groups. Their groups’ sizes range from just a few to more than 20 animals. These groups are led by the oldest female. She’s known as the matriarch. Elephants can live up to 80 years. “They have a huge wealth of experience,” says Phyllis Lee. She studies elephants in Kenya. For example, matriarchs use their memories to find water in times of drought.

Strength is an important leadership quality for other animals. Western lowland gorillas live in Central and West Africa. Their groups contain several females and their children. There is also a dominant male called a silverback. A silverback is six times stronger than an adult human. Its strength allows it to do its main job as a leader. That’s to fight off other males that try to take over the group.

Scientists have also found another useful trait in many wild leaders. That’s teamwork. African lions live in groups called prides. Prides have about 10 related females, their cubs, and a few males. The female lions work together to hunt. They also guard the pride’s territory and protect the young. “The females take responsibility for the pride and do that together,” says Craig Packer. He’s a lion expert at the University of Minnesota. 

Another common trait among successful animal leaders is attention to the needs of others. Lee has observed this trait in elephant matriarchs, who spend time playing with the young. Female gorillas value this trait in their leaders too. They may leave a silverback that doesn’t care for the babies. 

The silverback even  protects his group from day-to-day dangers, like crossing a road. “I’ve seen the silverback poke his head out and then sit and wait for the whole group to cross the road before following along afterwards,” says Morrison.
