For 290,000 years, modern humans had the same brain we have today. What did they do with it? And why does the official record say almost nothing?
The Investigation Wall organizes 290,000 years of suppressed, ignored, and unexplained evidence into 20 research arenas — each one a thread in the case for what humanity really was.
The Investigation Wall sends research teams to the world’s most important archaeological sites. Three continents. Five expeditions. Real evidence, captured on the ground.
The Investigation Wall is an open case. You can sponsor an expedition to help send a researcher into the field, or apply to join an expedition team yourself. Every contributor is etched into the permanent record.
Fund the fieldwork. Your contribution directly sends a research team to document evidence at the world's most important archaeological sites. Every dollar goes to flights, equipment, permits, and production.
Have relevant skills? Expedition teams need videographers, researchers, translators, archaeologists, drone operators, and production support. If you can contribute to the mission, apply.
The Investigation Wall is the hub. Each platform serves a different purpose in the prosecution — but all roads lead back to the same question.
