Homo ergaster

Homo argaster evolved from Homo habilis in Africa, developing traits like large noses and prominent sclera. They had smaller thoracic muscles, enabling primitive language, and adapted to control temperature through sweating. They were skilled in tool-making and had a large brain. Socially, they formed large groups based on family ties, hunted collectively, and migrated to Asia, becoming Homo erectus. They learned to use fire, transforming night into a time of safety and reflection.
