Whether any samples were retained for potential future genetic analysis is unclear from the published literature.

The underground environment of the sinkhole offered somewhat better DNA preservation conditions than open sites, but the warm Texas climate still presents challenges.

The question of what ancient DNA analysis of the Texas Archaic populations would reveal remains genuinely open and genuinely important.

The genetic picture of early Holocene North America is being assembled from sites across the hemisphere, and the Texas data — from one of the most environmentally significant and archaeologically productive regions of North America — would be a significant addition to that picture.

A second unanswered question concerns the precise population dynamics of the Texas Archaic period.
