The combination of the sandstone matrix and the ochre treatment likely contributed to the survival of the bone fragments over 13,000 years — though even with these advantages, the preservation was imperfect, and the remains were fragmentary by the time they were found.

The Second Opening: What the Genetics Changed

The publication of the Anzick genome in 2014 was one of those moments when a scientific result changes not just a specific debate but the framework within which an entire field of questions is asked.

To understand why, it is necessary to appreciate what the situation was before the genetic results arrived.

Before the Anzick genome was sequenced and published, the identity of the Clovis people — their biological relationship to modern Native Americans — was a matter of inference and debate rather than genetic fact.

The morphological characteristics of some early American skeletal specimens had led some researchers to propose that the earliest Americans were not closely related to the later Native American populations that Europeans encountered after 1492 — a debate that echoed arguments about the Lagoa Santa material from Brazil and similar early specimens from other parts of the Americas.
