Final answer:
The question about the storage unit in Las Vegas is not related to the research project described, which instead shows the 9,000-year-old grave discovery by Randy Haas in the Andes, challenging gender role assumptions in hunting during human history.
Step-by-step explanation:
According to the context of the research project presented, the student's question does not pertain to a real event regarding a storage unit in Las Vegas. Therefore, it is not possible to accurately answer whether it contained human remains, stolen goods, weapons, or artifacts. Instead, the information provided highlights the discovery by Randy Haas of a 9,000-year-old grave of a teenager buried with a hunting tool kit in the Andes mountains of Peru. This finding is significant as it challenges the traditional view that hunting was an activity exclusively conducted by men. The female hunter from prehistoric times is an example that contributes to our understanding of gender roles in human evolutionary history.
