The northeastern Siberian Arctic was not empty in the Pleistocene; it was simply not yet found by modern science.

The transformation of two ancient milk teeth into scientific knowledge involved a sequence of technical steps that is worth describing, not for its procedural detail but for what it reveals about the extraordinary effort required to read a 31,000-year-old genome.

The teeth were extracted from the permafrost sediment and carefully cleaned to remove surface contamination.
