What significant feature is associated with Homo erectus?

Homo erectus is notably associated with evidence of migratory patterns out of Africa, marking a key moment in human evolution. This species is believed to have emerged approximately 1.9 million years ago and was the first hominin to leave Africa, spreading into various regions of Asia and Europe. This migration reflects their adaptability and ability to survive in different environments, which is supported by archaeological findings such as tools and fossils found outside of Africa, illustrating their long-distance movements.

The other options do not accurately reflect the characteristics tied to Homo erectus. For instance, opposable thumbs were present in earlier hominins, and some archaic human species possessed tools, which contradicts the claim of a lack of tool use. Agriculture developed much later in human history, well after the time of Homo erectus.
