Homo erectus was a more intelligent and adaptable species than Homo habilis. Homo erectus people used intelligence to develop technology—ways of applying knowledge, tools, and inventions to meet their needs. These hominids gradually became skillful hunters and invented more sophisticated tools for digging, scraping, and cutting. They also eventually became the first hominids to migrate, or move, from Africa. Their brain size was 1000 cubic centimeters.
