The repeated use of the site — the evidence for multiple occupations at different levels within the stratigraphic sequence — documents a pattern of place use that speaks to the kind of landscape knowledge and seasonal planning that characterizes mobile hunter-gatherer groups in productive environments.

Returning to a known, productive site is both a practical and a cognitive act: it requires memory of where good resources are, planning for when to be in a particular place, and the social organization needed to coordinate group movement across a landscape.

These behavioral dimensions of the Upward Sun River evidence are not captured by the genome.

They are captured by the archaeological record — by the bones and tools and charcoal and structural evidence of occupation that the excavation team documented with careful precision over multiple field seasons.

The genome and the archaeology together tell a richer story than either could tell alone.
