• thread in Wednesday AMA: Mesoamerica

• Why didn't native americans develop bronze, iron or steel?

• What were characteristics of the Native American/First Nations fighting methods, and how did they develop? - just a mention

• What was war like in the Pacific Northwest before European contact?

• What did Chinese/Japanese civilizations believe was beyond the Pacific Ocean before the discovery of the New World? When did they first become aware of its existence?

• What was the pinnacle of Native North American boating technology - is there any history of larger, long-distance watercrafts used for cargo or transportation, or even naval warfare?

• Did the Native Americans and South Africans utilize metal body armor?

• thread in AMA: Alaska, from Prehistory to Present

• Have there ever been any Eskimo/Inuit conquerors/emperors/kings? - just a mention
