Homo ergaster was tall and muscular. Slim hips and long legs enabled this species to walk long distances. Their skin was smooth to cool themselves through sweating, meaning they no longer had to pant to keep cool.

Homo ergaster probably obtained food by scavenging or by chasing animals across the savannah until they died from exhaustion.

This species was amongst the first to leave Africa and colonize other continents. After ergaster leaves Africa, it becomes known as Homo erectus.

In Asia, Homo erectus lived in the bamboo forests and may have made tools such as staffs and spears from this strong, versatile material.
