Answers in Genesis biologist Nathaniel Jeanson uses this episode of They Had Names to claim that early North American mound cultures are a mystery sitting before the nations Europeans met. He says the opening of indigenous history looked unlike the scenes at contact, and that a first Native American world disappeared in the 400s AD. Poverty Point in northeastern Louisiana is his first case, a huge earthwork whose layout he says tracks the equinoxes. Adena mounds, widespread enough to turn up near modern towns, are the second. Hopewell earthworks in Ohio are the third, and he calls all three the work of unknown people. Effigy mounds farther west come later in his sequence. Ordinary ancestry tests, he argues, fade too fast to reach those builders, while Y chromosome comparisons work like a clock. On a biblical time scale he dates a split between Native American and Eurasian branches near the centuries of the Hopewell collapse. He ties that break to a later arrival. That is his claim about an earlier culture, not a finding about race.
Key points
- Jeanson says a first Native American world disappeared in the 400s and looked unlike contact scenes.
- Poverty Point is presented as a large Louisiana earthwork aligned with the equinoxes.
- Adena and Hopewell mounds are the next cultures, and he calls their builders unknown.
- Effigy mounds farther west come later in the sequence he sketches.
- He prefers Y chromosome comparisons to ordinary ancestry tests for reaching those centuries.
- A biblical clock and the Hun era are his proposed setting for a later arrival.
Short quotes
The history of North America can be told through its progression or series of earthwork mounds, burial mounds, and other structures.

I think we have independent evidence saying this type of DNA is unreliable.
Nathaniel Jeanson, Mound cultures before contact nations
