Three things that we learn about Homo erectus from this item:
1. Their range was more widespread than previously known (a substantial amount of their remains have been discovered in the middle east)
2. Fossils were known to them as they included them in their primitive craftmaking.
3. They believed in a power higher than themselves as some of the artifacts are believed by anthropologists to have served some form of religious purpose.
They were not a missing link or an ancestor of modern man. They were just as human as you and I.
