The specific genetic information that would complete the picture of Early Archaic Texas populations might be preserved in a site whose conditions were more favorable for DNA preservation than those of the known sites.

Science advances.

Methods improve.

What seems impossible today may be routine in a generation.

The specific question of ancient DNA from early Holocene Texas populations may be answered not from the known sites — whose physical evidence has been partially consumed by analysis and partially returned to the earth — but from new sites, excavated with new methods, under protocols developed with the benefit of the experience accumulated from earlier cases.

The limestone keeps its archives.
